Peanut Butter Mug Cake
Description
The Peanut Butter Mug Cake combines basic baking ingredients—flour, sugar, and baking powder—with milk, oil or melted butter, peanut butter, and a dash of vanilla to create a batter that cooks rapidly in a microwave. The addition of chocolate chips or a mini Reese’s peanut butter cup enriches the flavor with sweet pockets of melted chocolate. The quick cook time, typically 70 to 90 seconds, requires a light touch to avoid overcooking and maintain a soft, cakey texture.
Because microwaves vary, the resting period after cooking lets residual heat finish setting the cake evenly. This method yields a moist, single-serving cake ideal when you want a personal dessert without turning on the oven.
Variations include swapping chocolate chips for peanut butter chips, adding cocoa powder for a chocolate twist, or using gluten-free flour to suit dietary needs. The recipe is versatile and easily adapted based on available pantry items or preferences.
Ingredients
- ¼ cup all-purpose flour
- 2 1/2 Tablespoons granulated sugar
- ¼ teaspoon baking powder
- 2 Tablespoons milk
- 1 Tablespoon oil or melted butter
- 2 Tablespoons peanut butter
- vanilla extract dash
- 1 Tablespoon chocolate chips , or a mini Reese’s pb cup
Instructions
- Add flour, sugar, and baking powder to a mug and stir together.
- Stir in milk, oil or melted butter, peanut butter and vanilla extract until smooth, being sure to scrape the bottom of the mug. Stir in chocolate chips.
- Cook in microwave for 70-90 seconds* (until cake is just set, but still barely shiny on top). Allow to rest in microwave for 1 minute before consuming.
Notes
- Microwave times vary; start with 70 seconds then add 15-25 seconds if needed to avoid overcooking.
- The cake should be slightly shiny and soft in the center when done; it continues to set as it cools.
- Try substituting chocolate chips with peanut butter chips, toffee, or chopped Reese's cups for variety.
- Add a spoonful of Nutella or 1-2 teaspoons of cocoa powder for different flavors.
- Gluten-free flour can be used as a substitute for all-purpose flour.
