Chocolate fudge calories come to 70 for one 17 g piece and 410 per 100 g. Three quarters of those calories come from carbs, and nearly all of that is sugar: a single piece carries 12.4 g of sugars while protein barely registers at 0.4 g. Piece size, not the recipe, decides your total.

Three pieces of fudge cost 209 calories
A 17 g piece of homemade chocolate fudge is a small bite at 70 calories, about 3% of the daily value for energy. The trouble is that fudge is rarely cut that small. A 1 oz square weighs 28 g and lands at 115 calories, which is 6% of the daily value in one hand-sized block.
The total climbs quickly once you go back for more. Two 17 g pieces come to 139 calories, three reach 209, and five pieces, or 85 g, add up to 349. That last number is close to a light meal, and it disappears in a few minutes because fudge is dense and soft.
A full 100 g of fudge holds 410 calories, or 21% of the daily value. If you make your own slab, weigh one cut piece once and you will know what every piece from that pan is worth. Eyeballing works poorly here, since a slightly thicker square can carry noticeably more than you expect.
Sugar supplies three quarters of every calorie
The calorie split for chocolate fudge is lopsided: 75% carbs, 23% fat and just 2% protein. Per 100 g there are 76.7 g of carbs, and 73.1 g of those are sugars. Fiber comes to only 1.7 g, so almost nothing slows that sugar down.
Fat is the second source at 10.4 g per 100 g, and 6.4 g of it is saturated, which reflects the butter and chocolate in a classic recipe. That is less fat than many chocolate sweets, which is exactly why fudge reads lighter per 100 g than a bar or a truffle. The calories simply arrive as sugar instead.
Protein is close to zero at 2.4 g per 100 g and 0.4 g per piece, just 1% of the daily value. Fudge will not keep you full for long. Treat it as pure dessert energy, not as a snack that holds you over until dinner.
Fudge with nuts adds calories but trims sugar
Stirring walnuts or pecans into the pan shifts the numbers in both directions. A 28 g serving of fudge with nuts has 129 calories, against 115 for a plain 1 oz square. Fat nearly doubles, from 2.9 g to 5.3 g, because nuts are mostly fat.
The nuts also take up room that sugar would fill. Sugars drop from 20.5 g to 17.7 g per 28 g, carbs fall from 21.5 g to 19.1 g, and protein edges up from 0.7 g to 1.2 g. Fiber rises a little too, from 0.5 g to 0.7 g.
So the nut version is the slightly better pick if sugar is your main concern, and the plain one if calories are. Sodium is a non-issue either way: a 17 g piece carries 8 mg, and even 100 g has only 45 mg, about 2% of the daily value.
Plan fudge as a treat, not a snack
Because fudge brings sugar and little else, it fits best when you decide on the portion ahead of time. One or two 17 g pieces after a meal that already had protein and vegetables lands very differently from a 100 g handful eaten on an empty stomach.
Pairing helps. A piece of fudge next to a cup of coffee, a glass of milk or a bowl of berries turns it into a small dessert rather than a grazing session. If you watch sugar, the 12.4 g in a single piece is the number to remember, since it adds up quickly across three or five pieces.
Cholesterol is modest at 14 mg per 100 g, and potassium sits at 134 mg, so neither row changes the picture much. If you lose track during the holidays, BodyPal can log fudge from a photo, which makes it easier to see how many pieces actually went in.
How does chocolate fudge compare?
Here is chocolate fudge next to plain fudge, a chocolate bar and a chocolate truffle, per 100 g and per usual serving.
Verdict: Per 100 g, fudge is the lightest of these chocolate sweets at 410 calories against 531 for a chocolate bar and 510 for a truffle, so a 17 g piece of fudge at 70 or a 12 g truffle at 61 is the smallest hit. If sugar matters more to you than calories, the truffle and the bar are the better picks, with 44.9 g and 58 g of carbs per 100 g against 76.7 g for fudge.
