Process

Cook Mode

Note, these instructions are written assuming the standard serving size, since you have modified the number of servings, these steps may need to be modified for best results

In a small mixing bowl, whisk the egg until light and fluffy. This creates an airy texture in the mug cake.
Microwave the creamy peanut butter in a microwave-safe bowl for 15 seconds until soft. Be careful not to overheat.
Mix the sweetener into the melted peanut butter until smooth. Add the whisked egg and stir until fully combined.
Pour the mug cake batter into a large microwave-safe mug and microwave for 90 seconds. Cooking time may vary, so check for doneness.
Let the cake cool slightly before enjoying. Add toppings like sugar-free chocolate chips, whipped cream, or a drizzle of peanut butter sauce.

Notes

Use natural, unsweetened peanut butter for best keto results. Adjust sweetness by adding more or less keto sweetener. Microwave power varies - start with 90 seconds and check for doneness. Add sugar-free chocolate chips for a chocolatey twist!
