Method
Preparation
- Preheat your oven to 350°F (175°C) and spray a muffin tin with non-stick spray.
- In a large mixing bowl, beat together the butter and sugar with a mixer until creamy.
- Add the peanut butter, mashed bananas, milk, and vanilla extract, mixing until fully incorporated.
- Briefly beat in the eggs.
- Add the flour, baking powder, baking soda, and salt to the same bowl.
- Sift the cocoa powder into the bowl using a fine mesh strainer.
- Stir everything together until the batter is smooth and well-combined.
Baking
- Fill each muffin tin about ⅔ full with the batter.
- For the peanut butter swirl, add an overflowing ½ teaspoon of peanut butter to the top of each muffin and use a toothpick to gently swirl the peanut butter across the top.
- Bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
- Let the muffins cool in the tin for a few minutes before transferring them to a wire rack to cool completely.
Notes
Best served warm. Store in an airtight container for 3-4 days at room temperature, or in the fridge for a week. Freeze for up to 3 months.
