How many calories are in a slice of yellow cake?

A standard frosted slice, one twelfth of a two-layer cake at 67g, is 262 calories. The oversized bakery wedge closer to 110g is 430. Per 100g, yellow cake with vanilla frosting is 391 calories.

Yellow cake vs chocolate cake: which has more calories?

They are within a rounding error of each other, 391 calories per 100g for frosted yellow against 389 for frosted chocolate. Slice size decides the answer far more than flavor does.

How much sugar is in yellow cake?

41.8g per 100g, so a normal slice carries 28g and a large bakery slice carries 46g. That single big slice is nearly the entire 50g of added sugar suggested for a 2,000 calorie day.

Is yellow cake keto-friendly?

No, and not by a small margin. Net carbs run 55.9g per 100g, which puts one 67g slice at 37.5g, close to double a strict 20g keto day.

What makes yellow cake yellow?

Whole eggs and extra yolks, plus butter, where white cake uses egg whites only. That is also why the cholesterol reads 75mg per 100g, about 50mg in a slice, while a vegan sponge would read zero.

Does the frosting add much?

Less than people expect per gram, more than expected per plate. A homemade unfrosted piece of the same size is 245 calories against 262 frosted, but frosting is nearly all sugar and fat, so a thickly iced corner piece moves well past that.

Is yellow cake made from a box mix different?

The dry mix alone is a different food entirely, around 404 calories per 100g of powder, and it becomes cake only after you add eggs, oil and water. Judge a mix by what the finished slice weighs, not by the number on the box.

Does yellow cake have any protein or fiber?

Barely. It offers 3g of protein and 0.3g of fiber per 100g, which is 2g and 0.2g in a slice. Treat it as a dessert, not as part of the day's grain allowance.

How long does yellow cake keep?

A frosted cake holds three to four days at room temperature under a cover, since the frosting seals the crumb. Refrigeration dries it out faster than it preserves it, so freeze slices instead if you need more than a few days.
