Instructions
Here’s how to make Chocolate Peanut Butter Swirl Muffins:
Prepare the Muffin Batter:
- Preheat the Oven: Preheat your oven to 375°F (190°C) and line a 12-cup muffin tin with paper liners.
- Combine Dry Ingredients: In a large mixing bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt.
- Mix Wet Ingredients: In a separate bowl, whisk the granulated sugar, brown sugar, oil, eggs, vanilla extract, and milk until well combined.
- Combine Wet and Dry Mixtures: Gradually add the wet ingredients to the dry ingredients, stirring until just combined. Do not overmix.
- Fold in Chocolate Chips: If using, gently fold the chocolate chips into the batter.
Prepare the Peanut Butter Swirl:
- Mix Peanut Butter and Sugar: In a small bowl, mix the peanut butter with powdered sugar until smooth (optional for added sweetness).
Assemble the Muffins:
- Fill the Muffin Cups: Divide the muffin batter evenly among the prepared muffin cups, filling each about ¾ full.
- Add Peanut Butter Swirl: Drop small dollops of the peanut butter mixture onto each muffin and use a toothpick or knife to gently swirl it into the batter.
Bake the Muffins:
- Bake: Bake the muffins in the preheated oven for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
- Cool: Allow the muffins to cool in the tin for 5 minutes, then transfer them to a wire rack to cool completely.
