How to Make Chocolate Peanut Butter Swirl Muffins

Prep the Oven and Pan

Preheat your oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners or lightly grease each cup.

Mix the Dry Ingredients

In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, and salt until evenly combined.

Mix the Wet Ingredients

In a separate bowl, whisk together the buttermilk, oil (or melted butter), eggs, and vanilla extract until smooth.

Combine the Batter

Add the wet ingredients to the dry ingredients and gently stir just until combined. Avoid overmixing to keep the muffins light and fluffy. Fold in the chocolate chips if using.

Create the Peanut Butter Swirl

Fill each muffin cup about halfway with batter. Drop small dollops of peanut butter on top. Use a toothpick or skewer to gently swirl the peanut butter into the batter, creating a marbled effect.

Bake

Bake for 18–20 minutes, or until a toothpick inserted into the center comes out clean. Let muffins cool in the tin for a few minutes before transferring to a wire rack.

Tips for Success

• Warm the peanut butter slightly to make swirling easier.
• Do not overmix the batter to keep muffins fluffy.
• Use high-quality cocoa powder for deeper chocolate flavor.

Equipment Needed

• Muffin tin
• Paper liners or nonstick spray
• Mixing bowls
• Whisk or spoon
• Toothpick or skewer
• Wire cooling rack

Recipe Variations

• Double chocolate: Use dark chocolate chips for a richer bite.
• Crunchy swirl: Swap creamy peanut butter for crunchy.
• Mini muffins: Bake in a mini muffin pan for 10–12 minutes.
• Nut-free option: Use sunflower seed butter instead of peanut butter.

Serving Suggestions

Enjoy these muffins warm with a glass of milk, a cup of coffee, or hot chocolate. They also pair well with fresh fruit or yogurt for a more balanced breakfast.
