Baking Powder (1/2 teaspoon)
This leavening agent helps the mug cake rise, giving it a fluffy texture. It’s an essential component for achieving that perfect cake-like consistency in a microwave.
Unsweetened Cocoa Powder (1 tablespoon, optional)
For chocolate lovers, cocoa powder adds a rich, decadent flavor. It’s a low-carb option that complements the peanut butter beautifully without adding extra sugars.
