Ingredients

4 tablespoons all-purpose flour
4 tablespoons granulated sugar
2 tablespoons unsweetened cocoa powder
1 teaspoon baking powder
1 teaspoon salt
4 tablespoons milk (or dairy-free alternative)
2 tablespoons vegetable oil
1 tablespoon creamy peanut butter
1 teaspoon vanilla extract

Instructions

Begin by choosing a microwave-safe mug that holds at least 12 oz. In the mug, combine the all-purpose flour, granulated sugar, cocoa powder, baking powder, and salt. Using a fork or a small whisk, stir these dry ingredients together until they are thoroughly mixed, ensuring there are no lumps.
Next, incorporate the wet ingredients: pour in the milk, vegetable oil, creamy peanut butter, and vanilla extract.

Place the mug in the microwave and heat on high for 40 seconds. After this time, check the cake's doneness: it should rise and look set in the center. If the cake appears wet or undercooked, continue microwaving in 10-second increments until it is fully cooked.
