Description
A quick, indulgent single-serve dessert made in the microwave. This mug cake features a rich chocolate base with a gooey, molten peanut butter center, ready in just two minutes.
Ingredients
Scale
- 4 tablespoons all-purpose flour
- 3 tablespoons white granulated sugar
- 2 tablespoons unsweetened cocoa powder
- 1/4 teaspoon baking powder
- 1 pinch sea salt
- 1 tablespoon creamy peanut butter
- 3 tablespoons milk (whole, buttermilk, or non-dairy)
- 1 tablespoon vegetable oil or melted butter
Instructions
- Grease a large microwave-safe mug (at least 12 oz) lightly with butter or oil if desired.
- Add flour, sugar, cocoa powder, baking powder, and salt to the mug. Stir with a fork until combined and free of lumps.
- Pour in milk and oil (or melted butter). Add the peanut butter.
- Stir vigorously to incorporate the peanut butter into the batter, leaving a small swirl on top for the lava effect.
- Stir until the batter is smooth and glossy.
- Microwave on high for 1 minute and 30 seconds. Check if the top is set but the center is still slightly soft. If needed, microwave for another 15-30 seconds.
- Let the mug sit for 1-2 minutes to cool slightly and allow the lava to set. Enjoy warm.
Notes
Use a large mug to prevent overflow. Do not overcook, as the cake will continue to cook from residual heat. For best results, use good quality cocoa powder and creamy peanut butter. Can be made gluten-free by using 1-to-1 gluten-free flour and dairy-free by using almond/oat milk and oil.
