A character who really, really likes their sweets. Everything they eat could be classed as a dessert and if they drink tea it's got so much sugar in that the smell alone could kill a diabetic.
Sometimes identified as fuel for a hyperactive character. Another common version is for the Genius (see Gadgeteer Genius, Genius Ditz, Teen Genius) to require lots of sweets- they burn the sugars by thinking extra hard. Something of a Truth in Television: the brain uses glucose as its primary source of energy and not getting enough is bad. Real Life examples of the Sweet Tooth heed warning, however, because having too much sugar is also bad - not to mention the risk of cavities.
With adult characters, the same effect can be achieved with much lower doses—after all, most kids are nuts about the stuff to begin with. One frequent shorthand is to show someone adding huge amounts of sugar to tea or coffee (sometimes to the extent of an Overly-Long Gag), with a bystander looking on in horror. Another reason for an adult being obsessed with sugar can be to emphasise their immaturity (or more positively, "being in touch with their inner child").
May have some of the tendencies of the Big Eater. If they particularly enjoy lollipops, you may have an Oral Fixation on your hands. In kids' shows, may lead to An Aesop about tooth decay.
See also Genius Sweet Tooth, a subset of this Trope, which reflects the tendency smart people have for it.

Ranma Saotome is such an ice-cream lover that he's perfectly willing to use his much-hated Gender Bender curse to go with Akane to the local ice-cream parlor and gulp down all the parfaits he can without being recognized by others.
Nabiki, too. She's seen eating ice cream pretty often. And then there's the first season anime episode where she buys, and clearly intends to finish off in one sitting, a dish of pudding ala mode, a chocolate parfait, a serve of cheesecake, a strawberry tart and a slice of pumpkin pie.
On one hand, in Ranma's case, there's an implication (which is eerily plausible, given what we know of Genma) that he's actually never eaten ice cream before in his life until he came to Nerima. On the other hand, however, Genma also has a sweet tooth in the anime; in fact, he actually threatens to disown Ranma after Ranma eats some sweets that Genma was saving (he won't really go through it, though; he's just throwing a temper tantrum in hopes of intimidating Ranma into apologizing. It doesn't work, as Ranma knows Genma too well).
Hinako Ninomiya is seriously obsessed with candy while in her child form.
Count D (Petshop Of Horrors). Leon regularly gets information out of him by bribing him with chocolate.
In Death Note, one of L's many Bunny-Ears Lawyer characteristics is his fondness for an enourmous amount of sweets. He thinks so hard that his brain burns up all the calories and allows him to stay lean. Mello takes after him in this regard, but only for chocolate. His calling card is biting into a chocolate bar, which makes a snap like a thunderclap... To Memetic Levels.◊
In Futaba-kun Change!, Misaki has an extreme sweet tooth and when she switches from swimming club to wrestling club so her new friend "Futaba-Chan" won't be the only girl in it, there is a joke about how it turns out that none of the other swimmers actually know how to swim in regular water that isn't filled with dissolved sugar from Misaki's sugar-filled body.
Understatement. This is a girl who starts with a container full of sugar and adds tea.
He eats so inhumanly much without ever gaining weight that his younger brother was convinced he's sort of alien (though the lack to weight is probably because of how much energy he regular exerts).
By "inhumanly," we're talking three whole cakes for desert after dinner. And every week he eats several cakes as a sort of feast. Note that these are huge cakes that probably wouldn't be out of place in a wedding.
In fact, his obsession with sweets is such that:
He chooses keeping his cakes and other sweets over reconciling his differences with the aforementioned brother.
When he is forced to abstain from sweets due to a toothache, he shows the rest of the club EXACTLY why they must Beware the Nice Ones. *shudders*
Legato in Trigun. Eating cheesecake has never been so creepy.

Gintama: The first thing we see Sakata Gintoki doing is violently knocking an Amanto dignitary unconscious... because said dignitary tripped Shinpachi, who spilled Gintoki's chocolate parfait. Yep. The man has the word "sugar" on a plaque on the wall of his...office.
Ryoko Kurosaki in Kemeko Deluxe!! really has a thing for sweets. This becomes very clear when the squeals of delight and visual effects used to show her enjoying the sweets she's mooching off Sanpeita make it seem like she's in the throes of lovemaking.
While Mahoujin Guru Guru's Kukuri likes sweets as much as any youngster, she had never in her life eaten chocolate, due to her foster mother convincing her chocolate was deadly to children to keep Kukuri out of her private stash. When she realizes this and finally tries some, she becomes addicted to the point of spending all her and Nike's cash on chocolate treats and can be seen munching on it off and on from then on. To be fair, Guru Guru being a Role-Playing Game Verse, the chocolate has a practical effect of replenishing MP.

Xerxes Break from Pandora Hearts is a spectacular example: not only he can eat a dozen portions of cake at one scoop and never parts with his precious box of candies, but he steals sweets from other characters, and is capable of pushing into his mouth half of a saucer with cake remains on it - in order to lick it off.
Killua from Hunter × Hunter managed to spent several millions in sweets in DAYS. The chocolate shop couldn't keep up.

Yuusuke in Ame Nochi Hare, who asserts that lack of sugar slows down his mind.* Toru from Iris Zero, to the point of abandoning his main principle. Minimal exposure < Cake
Used as a clue to the murderer's identity on an episode of Case Closed. The victim was poisoned by his adoptive mother, and it was believed that the poison came from a chocolate bar given to him by one of his friends for Valentine's Day. The victim's little brother wasn't allowed to have any candy because his mother said he had cavities, but she let him have some cake after Ran let him try some of her coffee. Conan realized that the victim was poisoned by the coffee. When the mother pointed out that everyone had coffee, Conan retaliated that the victim was the only one who didn't have the cake, which probably had an antidote. As to why the victim, who didn't like sweets, had taken the friend's chocolate bar (which the mother replaced with one with poison in it), it was because the victim secretly liked the girl who gave it to him and would've eaten it anyway. (The girl who gave him chocolate reminded him of his dead biological mother)
In Kotoura-san, Haruka is one—this is the only thing she gave to the class when she introduced herself when she transferred in the manga. In the anime this trait was only alluded to and not stated as explicitly.
Kei Kugimiya from Ginga Kikoutai Majestic Prince. She enjoys (and makes) sweets that are intolerable by normal human standards. When she tries a normal cake out (that her teammates rave about), she actually finds the taste bland.
Keitaro's adopted sister Kanako from Love Hina averts this since she's always hated sweets. So of course she was adopted by a family of confectioners who kept feeding her their creations.

Changelings in general love chocolate as well.
A large number of Harry Potter fanfics present Lupin as a bit of a chocoholic, probably just in case the presence of a huge block of chocolate in his luggage at the beginning of the third book wasn't sufficiently explained by the fact he was the Defense Against the Dark Arts professor at the time, he knew that there'd be Dementors at Hogwarts and chocolate helps people who've been around Dementors, and he's almost always quite sensible.

Sloth eventually breaks free of the chains holding him to do so, causing Chunk to comment, "Gee, mister, you're even hungrier than I am!" Later, the two of them raid the freezer for ice cream.
Honor Harrington's genetically enhanced metabolism requires regular stoking, preferably with hot cocoa.
In The Nutcracker and the Mouse King (the original short story and not the ballet), Marie and the Nutcracker visit a kingdom where practically everything, from Marzipan Castle to Marmalade Grove, is made of sweets. The Nutcracker tells her the story of a giant named Sweettooth who nearly ate the entire kingdom. In the end the citizens made a deal with the giant: they would let him have part of the Castle and a good portion of the Grove without a fight and in return he would leave peacefully after he was done.
Carrying on from the Italian example noted above, Salieri of Amadeus has an obsession with sweets, especially marzipan, and after making his Faith Heel Turn, that's one of the first things he is able to indulge in to the fullest. As an example of stereotypes sometimes being Truth in Television, this aspect (unlike the killing Mozart one) was true of the actual Salieri as well.
And anyone who's been Dementor'd will seriously appreciate a chocolate bar.

The Beatles' "Savoy Truffle" was George Harrison's ode to Eric Clapton's notorious jones for sucrose (with a darker subtext, if you're aware that heroin addicts often seem to prefer sweets to real food). A bit sadistic, regardless: think of the bridge ("You might not feel it now...") BTW "Good News" is an English brand of chocolates; think Whitman or Russell Stover for an American equivalent.
All sweets despite the consequences in Sugar Rush by Anthony and Those Other Guys.
Calvin from the Calvin and Hobbes comic strip was a demonstratively very intelligent, uber-active (to a fault) little kid whose imagination knew absolutely no bounds. His favorite food was a breakfast cereal named, "Chocolate-Frosted Sugar Bombs". With a lot of added sugar. And chocolate milk. They make it with marshmallow bits but his mum won't buy that for him. He once tried it with soda instead of chocolate milk, but the bubbles went up his nose.
The was also the time that Calvin made sandwiches for himself and Hobbes as rations for an ill-planned journey to Yukon, Alaska. They were marshmallow sandwiches, with one containing honey and the other chocolate syrup.
All three of the Fox children from FoxTrot, but Paige moreso than her brothers. In one comic mother Andy catches the boys eating their chocolate Easter bunnies early and bawls them out, pointing out that Paige hasn't touched her hollow rabbit at all; the boys comment that the rabbits are solid chocolate. In the last panel, as Andy yells "Paige, get down here!", Jason wonders when she was alone with the candy for more than five seconds.
In another one with Easter bunnies, Peter and Jason are having an impromptu eating contest to see who can eat their bunny (a pound of solid chocolate!) the fastest. Andy chews them out for this and points out that she doesn't see Paige eating hers. Peter explains that Paige already won the contest — Peter and Jason are battling for second place.
In another strip, Andy sends her to the store for Halloween candy. She buys so much, the shopping cart breaks.
During one of her Pierre dreams, Paige receives two chocolate bunnies the size of mountains.
She loves ice cream too; in one summer strip, she buys the entire inventory of an ice cream truck.
Andy has this weakness too; she tries to suppress it, being a health food nut, but on Halloween and Easter, she occasionally loses it. In a 2013 strip, she stole from the kids' Easter baskets after giving up candy for Lent.

Ema Skye in Apollo Justice: Ace Attorney, and her Snackoo obsession.
And Tyrell Badd with his constant lollipop.
Tytti Noorbuck from Super Robot Wars likes sweets. Unfortunately, she lets her feelings override her preference (or sense) of taste, thereby turning her into a Lethal Chef and according to her teammates, logic gets thrown out of window when it comes to sweets. She thinks Cliana Rimskaya's Strawberry Jam Riceball is tasty and wouldn't mind more strawberry jams in it. And if she drinks her tea, she'd at minimum put six cubes of sugar.
Yuuki: E... eight cubes of sugar...?
Tytti: I thought I was being modest...

Classic computer Video Game star Commander Keen, might count. Pretty much every bonus-point item is candy, especially from Keen Dreams onward. In fact, the 5,000-point item in the fifth game is a plain 'ol bag of sugar.
In Castlevania: Rondo of Blood, the item that restored Richter's health was the classic meat. Maria, the other playable character and a twelve-year-old, restored her health with ice cream sundaes, lolipops, cakes, and ice cream. She actually has more variety of health power-ups than Richter does!
Laharl and Etna from Disgaea both have enormous sweet teeth, and the former's confiscation of the latter's expensive snacks is a frequent point of contention between the two, particularly in Disgaea Infinite.
Professor Rowan from Pokémon Diamond and Pearl, although it isn't obvious. You first find out that he has a thing for candy if you check out the refrigerator in his lab at the beginning of the game. (It's full of sweets.) Later, when after you beat the game, you can find him in the lower floor of the Veilstone City Department Store; if you speak to him, he complains about the Rage Candy Bars still being out of stock before he speaks to you.
For that matter, Pokémon in general. Lots of Power Ups you use on them are sweet foods, like Soda Pop and Lemonade in all the games, which restores their hp, along with Lava Cookies, Old Gateau (sponge cake), Casteliacones (ice cream), and Lumiose Galettes (cookies again) which cure Condition, each one unique to a certain Generation. Rage Candy Bars and the chocolate Sweet Hearts can restore a little HP for a Pokémon in most versions (but they usually have other uses too). There were also Poffins in Diamond and Pearl, which you made from Berries and fed them to enhance their Contest stats, and most recently, X and Y introduces Poké Puffs, cupcakes you can feed them during the Poké Anime Mini-Game that they clearly love, and Poké Juice, special drinks made from berries that give them a variety of benefits.
Sugar, or at least its aroma, is known to attract witches in the Left 4 Dead series. One part of the "Hard Rain" campaign in Left 4 Dead 2 revolves around navigating a sugar mill completely infested with this strain of infected - they may be as many astwentyof themnote (if you find two witches in any other single segment of a campaign, it's a sign that the Director is going sadistic on you), sometimes right beside each other. Thankfully, they disperse when the rain starts and the smell (presumably) dissipates.
This is an Ascended Glitch - the Director's algorithm for the area is screwed up, resulting in the Witch hordes.
The Monster Clown from Twisted Metal named Sweet Tooth (Actually his name is Needles Kane but is rarely referred to it even in game, suggesting it is an alias he uses for himself) is rumored to have a massive craving for sweets which he keeps in the freezer of his ice cream truck, along with his victims.
Gaius from Fire Emblem Awakening. He's sucking on a lollipop in his face portrait, has a number of additional lollipops on his belt in his full portrait, and his official profile describes him as carrying fifty different kinds of "emergency snacks" on his person.
Even his recruitment talk is about sweets. He's reluctant to join Chrom's group and says something about "sweetening the deal", Chrom assumes he's taking about being paid... and then Chrom drops some candies that he was keeping for his sister. From then on, Hilarity Ensues.
To a smaller degree, there's Olivia. In her supports with Gaius himself, she becomes his beta tester for his pies.
"Can't talk. Eating!"
Om Nom from Cut The Rope. The goal of the game is to feed him candy.
Peacock from Skullgirls considering the fact that "Junk Food" is listed as one of her likes.
Kokonoe from BlazBlue has a habit of collecting sweets from all over the world, though she never openly admits it. Just look at the image provided here◊; it shows her holding the candy in her hand most of the time. In Tager's story mode for BlazBlue: Continuum Shift, she even instruct Tager to prioritise a mission that will reward her with... a rare chocolate.
Tager: Whatever it is you're trying to get from these people must be awufully important... I never knew you to have such a... generous side...'''
Kokonoe: Giving this mission maximum priority hardly does it justice. Its a box of cho-ah... from Roch-... er... um... parts.'''
Both Kula and Maxima from The King of Fighters. Kula is always seen licking lollipops and several of her talks feature how much she loves ice-cream; on the other hand, Maxima openly admits that Real Men Hate Sugar does NOT apply to him, and he is able to put out a MASSIVE parfait in few seconds. (It's more understandable in his case; glucose is the fuel for brains, and he's a powerful Technopath as well as a Cyborg)
"The food of Elsweyr is invariably sweet; candies, cakes, puddings, and sugarmeats are the staples of the khajiit diet, and travelers to Elsweyr are cautioned against partaking of any of the native food."
Alain from HOME is addicted to sugar, so much that he eats an entire room full of it.
Komari from Little Busters has this as one of the biggest parts of her character. By her logic, when you eat sweets, you feel happy, so she eats them all the time. When you share sweets with someone else, it's even better, because their happiness causes you to feel happier, which causes them to feel happier, in a big, sugary cycle.
One way to calm down Nefarious from Emergency Exit is to give him candy. "You can defeat demons with chocolate?" "Apparently we've been going about it all wrong." -Fall and David from the crossover with Parallel Dementia.
Robin DeSanto of Shortpacked is prone to attacks of ludicrous hyperactivity when she engages in her habit. Famously, on one occasion she enjoyed a breakfast cereal of Cadbury cream eggs in chocolate syrup; she regained consciousness to find she'd been elected to congress.

This is a common Weaksauce Weakness among bacteria villains in Ozzy and Drix; they can't resist anything sweet. They can be lured into a trap or ambush with simple pastry. (Of course, for a very big bacteria, you'd need a pretty big pastry.) Even the criminal mastermind Strepfinger was apprehended after Maria lured him out of his office with a pie. (After she knocked him out, she said, "You know, for an evil genius, you're pretty dumb.")
The already mentioned Martian Manhunter keeps his love of Oreo Choco cookies in Justice League.
Also, when The Flash is offered coffee by the police in one episode, he asks for it with "cream and twenty-seven sugars". (Somewhat justified in his case, as he seems to have a very high metabolism due to his powers.)
Timmy and Wanda from The Fairly OddParents. to the point that when Timmy considers wishing for all of the daily meals to be just desserts, Wanda eagerly gives in becaue it means she'll get to eat as much chocolate as she wants.
Possibly Discord. Among other things, he uses his reality warping powers to make chocolate milk rain (though he prefers the glass to the milk itself), cotton candy clouds and flying pies, though only Pinkie partakes of any of this delicious mayhem.
In the episode "Ponyville Confidential", the Cutie mark Crusaders get a picture of Princess Celestia ravenously devouring cake.

Don't ever give Daphne chocolate, unless you want her to turn into Gollum.
