Calories per slice of a cake cut into 10

    Five ingredients, one total - the calorie count your recipe never shows. Enter up to 8 baking ingredients with weights to get total calories, per-serving calories and a full protein/fat/carb breakdown.

    With 10 selected the arithmetic takes a different route. The tin does not change, so the slice count is the only lever left, and it moves the number on the plate more than any ingredient swap. This page opens the calculator with 10 already selected, so only the remaining fields are left to fill in. Change the other fields to your own numbers and press the button; the formula appears under the answer.

    The calorie count your recipe never shows

    A classic cheesecake with 250 g of mascarpone and 200 g of sugar packs over 3,200 kcal in total. Cut into 12 slices, each one carries about 267 kcal - and that is before the whipped cream on top. This calculator takes your exact ingredient list, adds up every gram and breaks the result into total calories, per-serving calories and a full protein/fat/carb split.

    735
    kcal per 100 g of butter - the most calorie-dense baking ingredient
    884
    kcal per 100 g of vegetable oil - even more than butter
    52
    kcal per 100 g of apples - lightest ingredient on the list
    660
    kcal per 100 g of shredded coconut - a hidden calorie bomb

    How to use the calculator - step by step

    1. Number of ingredients - select how many ingredients your recipe has (2-8). The matching fields appear automatically
    2. Pick each ingredient - choose from 30 common baking items: flours, sugars, fats, dairy, chocolate, nuts, fruit and leaveners
    3. Enter the weight in grams - for eggs, use 60 g per egg as a shortcut
    4. Set the number of servings - how many slices or portions you plan to cut
    5. Read the results - total kcal, per-serving kcal, macro breakdown (protein/fat/carbs) and a detailed table showing every ingredient's contribution

    FAQ

    Does baking change the calorie count?
    Only marginally. Water evaporates during baking, so the weight drops but the calories stay the same (you do not bake away fat or sugar). The per-100 g concentration increases slightly (2-5%), but the total calorie count of the whole recipe remains virtually unchanged.
    Why is butter so calorie-dense?
    Butter is 81% fat, and fat contains 9 kcal per gram (vs. 4 kcal for protein and carbs). That makes 100 g of butter 735 kcal - almost twice as much as the same weight of sugar. Replacing butter with applesauce (1:1 by weight) in muffin recipes can cut calories by 40-50%.
    How do I count eggs in grams?
    One medium egg (without shell) weighs about 60 g. A large egg is closer to 65 g. For recipes calling for 3 eggs, enter 180 g. Egg whites alone are about 33 g per egg, yolks about 17 g.
    Can I reduce calories without changing the recipe too much?
    Three easy swaps: (1) Replace half the butter with Greek yogurt - saves ~350 kcal per 100 g swapped. (2) Use 70% of the sugar the recipe calls for - most baked goods taste fine. (3) Add fruit (apples, bananas) for moisture instead of extra fat. The calculator lets you compare both versions side by side.
    What is the most calorie-dense baking ingredient?
    Vegetable oil at 884 kcal/100 g, followed by butter (735), shredded coconut (660), walnuts (654) and almonds (579). All of these are high-fat ingredients. On the other end, apples (52), milk (50) and baking powder (53) contribute almost nothing.
    Are these values accurate for all flour types?
    The calculator includes all-purpose flour (340 kcal), rye flour (325 kcal) and potato starch (333 kcal). Whole wheat flour has similar calories (~340) but more fiber and protein. Almond flour is significantly higher (~580 kcal) due to fat content - use the "almonds" option as a close proxy.
