Quick and easy chocolate peanut butter mug cake. It has the best flavor and only takes 5 minutes to make! Did I mention it will always come out tender and moist?!
In a mug, add in the butter and peanut butter. Microwave for 30 seconds and stir.
Add in the brown sugar, flour, and cocoa powder. Stir until combined.
Add in the milk and stir until the batter is smooth.
Place into the microwave for 2 minutes. If you need more time, start at 20 - 30 seconds. The more you microwave it, the dryer it will get.
Add the teaspoon of peanut butter into a sandwich bag. Microwave for 20 seconds and squish the peanut butter around. Cut a small corner out of the sandwich bag. Drizzle peanut butter on top of the warm mug cake.
