Chocolate Peanut Butter Swirl Muffins Recipe
Introduction
Chocolate Peanut Butter Swirl Muffins combine rich cocoa with creamy peanut butter in a moist, tender bite. Ready in just 35 minutes, these muffins are perfect for breakfast or a sweet snack any time of day.

Ingredients
- 1 3/4 cups all-purpose flour
- 1/2 cup granulated sugar
- 1/4 cup unsweetened cocoa powder
- 2 teaspoons baking powder
- 1/2 teaspoon salt
- 3/4 cup buttermilk (or milk with 1 tablespoon vinegar or lemon juice)
- 1/2 cup vegetable oil (or melted butter for richer flavor)
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/3 cup creamy peanut butter
- 1/2 cup chocolate chips (optional but recommended for added richness)
Instructions
- Step 1: Preheat the oven to 375°F (190°C) and line a muffin tin with paper liners.
- Step 2: In a bowl, whisk together the flour, sugar, cocoa powder, baking powder, and salt until evenly combined.
- Step 3: In a separate bowl, whisk together the buttermilk, vegetable oil (or melted butter), eggs, and vanilla extract until smooth.
- Step 4: Pour the wet ingredients into the dry ingredients and gently stir until just combined. Avoid overmixing. Fold in the chocolate chips if using.
- Step 5: Spoon the batter into each muffin cup, filling them about halfway. Drop small dollops of creamy peanut butter on top of the batter in each cup.
- Step 6: Use a toothpick or skewer to swirl the peanut butter into the batter, creating a marbled effect.
- Step 7: Bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
- Step 8: Let the muffins cool in the tin for a few minutes before transferring them to a wire rack to cool completely.
Tips & Variations
- For a richer taste, substitute vegetable oil with melted butter.
- Try crunchy peanut butter for added texture in the swirls.
- Add chopped nuts or swap chocolate chips for peanut butter chips for a twist.
- If you don’t have buttermilk, mixing regular milk with lemon juice or vinegar works perfectly.
Storage
Store the muffins in an airtight container at room temperature for up to 3 days. For longer freshness, refrigerate them for up to a week or freeze for up to 3 months. To reheat, warm in the microwave for 15-20 seconds or in a preheated oven at 300°F (150°C) for 5-7 minutes.

FAQs
Can I use natural peanut butter instead of creamy?
Yes, natural peanut butter can be used, but it may be a bit less smooth to swirl. You might want to stir it beforehand to ensure even consistency.
Are these muffins dairy-free if I use milk with vinegar instead of buttermilk?
Using milk with vinegar or lemon juice still contains dairy. For a dairy-free version, substitute with a plant-based milk such as almond or soy milk mixed with vinegar.
