Almond Flour

Erythritol

Erythritol (1 tablespoon) is a sugar substitute that provides sweetness without the calories or carbs. It helps keep this dessert keto-friendly while ensuring you can indulge without guilt.

Egg

The large egg (1) acts as a binder, enhancing the cake’s structure and adding protein. It also contributes to the rich, fluffy texture of the finished dessert.

Baking Powder

Baking powder (1/2 teaspoon) is essential for giving the mug cake its rise, ensuring it is light and fluffy rather than dense. This ingredient is crucial for achieving the perfect mug cake consistency.

Vanilla Extract

Vanilla extract (1 teaspoon) adds a warm, aromatic flavor that elevates the overall taste of the cake, making it even more enjoyable. It’s a simple addition that makes a big difference in flavor.
