How many calories are in a slice of carrot cake?

A restaurant or bakery slice runs about 200g, which is 748 calories. A carrot cake cupcake at 90g is 337. Per 100g the cake is 374 calories, and the reason a slice reads so high is simply that the slices are enormous.

Is carrot cake healthier than chocolate cake?

Barely, and not for the reason people assume. Carrot cake is 374 calories per 100g against chocolate cake at 389 and yellow cake at 391. The gap is noise. Carrot cake also tends to be cut thicker and carries cream cheese frosting, so the slice on the plate usually wins on calories.

How much sugar is in carrot cake?

38.5g per 100g, so 77g in a 200g slice and 35g in a cupcake. That slice is about 18 teaspoons of sugar, roughly triple the American Heart Association's daily ceiling for women. Most of it is in the frosting and the batter, not the carrots.

Do the carrots make it a vegetable serving?

No. The vitamin A is real at 100mcg per 100g, but fiber tells the story: 1.1g per 100g, so a 748-calorie slice delivers 2.2g, roughly one raw carrot's worth. Grated carrot in a cake behaves like moisture and sweetness, not like a vegetable on your plate.

Is carrot cake keto-friendly?

Not remotely. A slice carries 101g net carbs, five times a strict keto day's entire allowance, and even a cupcake is 46g. Almond flour versions built for keto exist, but those are a different recipe rather than a smaller slice of this one.

How much fat is in carrot cake?

17.5g per 100g, which is 35g in a slice. Only 3.2g of that per 100g is saturated because most carrot cake recipes use oil rather than butter. Oil is also why the crumb stays moist for days where a butter cake goes stale.

Does carrot cake have nuts?

Usually walnuts or pecans, sometimes both, sometimes neither. There is no standard recipe, so a nut allergy makes carrot cake a question you have to ask rather than assume. Nuts add roughly 20 to 30 calories per slice on top of everything above.

How many calories does the frosting add?

Cream cheese frosting runs 415 calories per 100g, and a generous layer on a bakery slice is 50 to 70g of it, so 208 to 291 calories of the 748 are frosting alone. Scraping half of it off is the single biggest cut available.

How long does carrot cake keep?

Frosted with cream cheese, it belongs in the fridge and lasts four to five days. Unfrosted layers hold two days on the counter or three months wrapped in the freezer. The oil-based crumb stays soft much longer than a butter cake does.
