How do you make a 3 ingredient peanut butter mug cake?

Omit the cocoa powder if you want a peanut butter-only flavor. Use 1 egg and 2 tablespoons of peanut butter, plus ¼ teaspoon baking powder for a fluffier result. Stir, microwave, and enjoy.

Can you make a mug cake without sugar?

Yes! This recipe is naturally sugar-free and keto-friendly. If you prefer it sweeter, add your favorite keto sweetener like stevia, erythritol, or monk fruit—but it’s completely optional.

What ingredients do I need for mug cake?

You only need three: one large egg, peanut butter (or almond butter), and unsweetened cocoa powder. Optionally, add vanilla, sweetener, or baking powder to tweak texture and flavor.
