Angel Food Mug Cake

Ingredient Notes

Egg White:
Egg whites create the classic light, fluffy texture of angel food cake. They help the batter rise and stay airy. Whip them until foamy before mixing for best results.

Almond Flour:
Almond flour adds structure and a mild, nutty flavor while keeping the recipe low-carb. It helps maintain a soft, moist crumb. Use blanched almond flour for a smooth, delicate texture.

Coconut Flour:
Coconut flour adds fiber and helps absorb excess moisture. It keeps the mug cake from becoming dense and balances the almond flour. Use sparingly—coconut flour absorbs a lot.

Erythritol Powder:
A zero-calorie sweetener that blends smoothly and sweetens without bitterness. Powdered erythritol gives the mug cake the best texture.

Vanilla Essence:
A touch of vanilla enhances the cake’s sweetness and aroma, giving it the classic angel food flavor. Just a few drops are enough.

Cream of Tartar:
This stabilizes the egg whites and helps the mug cake rise. It creates the signature cloud-like, fluffy texture.

Salt:
Just a pinch helps bring out the sweetness and enhances all the other flavors.

Water:
Adds a little moisture and ensures the batter mixes smoothly. It also prevents the cake from becoming dry in the microwave.

FAQs

Can I use a whole egg instead of egg whites?
No. A whole egg will make the cake dense. Use only egg whites for the signature fluffy texture.

Can I bake this mug cake in the oven?
Yes! Bake at 350°F (175°C) for about 10 minutes.

Can I make this cake using only almond flour?
You can, but it will be heavier and less airy. A mix of almond and coconut flour gives the best texture.
