Ingredients
For the Muffins
- 1 ½ cups all-purpose flour
- ½ cup unsweetened cocoa powder
- 1 teaspoon baking soda
- ½ teaspoon baking powder
- ½ teaspoon salt
- ¾ cup granulated sugar
- ½ cup brown sugar
- ½ cup vegetable oil (or melted coconut oil)

How to Make Chocolate Peanut Butter Swirl Muffins
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners to prevent sticking.
Step 2: Mix Dry Ingredients
In a medium bowl:
1. Whisk together the flour, cocoa powder, baking soda, baking powder, and salt. Set aside.
Step 3: Combine Wet Ingredients
In a large bowl:
1. Whisk together the granulated sugar, brown sugar, vegetable oil, eggs, and vanilla extract. Mix until smooth.
2. Add the buttermilk, mixing until fully combined.
Step 4: Combine Wet and Dry Mixtures
Gradually fold the dry ingredients into the wet mixture using a spatula:
– Mix until just combined. Be careful not to overmix; it’s okay if there are a few lumps.
Step 5: Prepare the Peanut Butter Swirl
In a separate bowl:
1. Stir together the creamy peanut butter, powdered sugar, and milk. Mix until smooth.
Step 6: Fill Muffin Cups

Step 8: Bake
Bake in your preheated oven for 18–20 minutes. Check for doneness by inserting a toothpick into the center; it should come out mostly clean.
Step 9: Cool
Let muffins cool in the pan for about 5 minutes before transferring them to a wire rack. Serve warm or allow them to reach room temperature before enjoying.
