Method
 

Step-by-Step Instructions for Chocolate Peanut Butter Mug Cake
  1. In a microwave-safe mug (at least 12 oz), add the dry ingredients: all-purpose flour, granulated sugar, unsweetened cocoa powder, baking powder, and a pinch of salt. Whisk these together until well combined.
  2. Pour in the wet ingredients: your choice of milk (dairy or dairy-free), creamy peanut butter, vegetable oil, and a splash of vanilla extract. Stir the mixture vigorously until you achieve a smooth and luscious batter.
  3. For an extra layer of decadence, fold in a small handful of chocolate chips to the batter, if desired.
  4. Place the mug in the microwave and cook on high for 1 minute and 30 seconds. Check the center by gently pressing it; it should be set but slightly moist.
  5. Allow your Chocolate Peanut Butter Mug Cake to cool for about 1 minute once it’s done cooking; serve it warm.
