- Salt (¼ teaspoon): Enhances the overall flavor and balances the sweetness.
- Granulated sugar (¾ cup): Sweetens and contributes to the tender crumb.
- Large eggs (2): Bind ingredients and add richness.

How to Make Chocolate Peanut Butter Swirl Muffins Recipe
Step 1: Preheat and Prepare
Start by preheating your oven to 375°F (190°C) and line a muffin tin with paper liners. This step sets you up for perfectly baked muffins with no sticking, ensuring a clean and easy release once they’re golden and ready.
Step 2: Mix the Dry Ingredients
In a large bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking powder, baking soda, salt, and granulated sugar. Combining these dry ingredients first ensures that your muffins will have even distribution of flavors and a consistent texture.
Step 3: Combine the Wet Ingredients
In a separate bowl, whisk the eggs, milk, vegetable oil, and vanilla extract until the mixture is smooth and homogenous. This wet mix will bring moisture and richness to the batter, balancing out the dry components beautifully.
Step 4: Mix Wet and Dry Ingredients
Pour the wet ingredients into the dry bowl and gently stir until just combined. Avoid overmixing to keep the muffins fluffy and tender. A few lumps are perfectly okay here — they’ll bake out nicely.
Step 5: Prepare the Peanut Butter Swirl
In a small bowl, mix the creamy peanut butter with powdered sugar until the texture is smooth but thickened enough to hold its shape when spooned on top of the batter. This mixture will create those irresistible swirls that make these muffins so special.
Step 6: Assemble the Muffins
Fill each muffin liner halfway with the chocolate batter. Add a spoonful of the peanut butter mixture on top, then finish filling with more chocolate batter until each cup is about three-quarters full. Use a toothpick or knife to gently swirl the peanut butter into the chocolate batter, creating beautiful marbled patterns that are a feast for the eyes and palate.
Step 7: Bake to Perfection
Bake the muffins for 18 to 20 minutes, or until a toothpick inserted into the center comes out clean. This ensures your muffins are fully cooked but still moist and tender inside.
Step 8: Cool and Enjoy
Allow the muffins to cool in the pan for 5 minutes before transferring them to a wire rack. Cooling helps set the muffins’ structure and makes them easier to handle, so each bite is as satisfying as the first.
How to Serve Chocolate Peanut Butter Swirl Muffins Recipe

Garnishes
Dust your muffins lightly with powdered sugar or top with a few chocolate chips right before serving to add an extra touch of sweetness and visual appeal. A small dollop of peanut butter or a drizzle of melted chocolate makes them feel extra special for guests or a personal treat.
Side Dishes
Serve these muffins alongside a steaming cup of coffee, rich hot chocolate, or your favorite milk for a mini celebration of flavors. Fresh fruit, like strawberries or banana slices, also pairs wonderfully to balance the richness of the chocolate and peanut butter.
Creative Ways to Present
For a brunch gathering, arrange the muffins on a pretty platter lined with parchment and scatter chopped peanuts or cacao nibs around them. You could also slice one horizontally and spread a little extra peanut butter inside for a layered treat. These muffins shine with a bit of flair!
Make Ahead and Storage
Storing Leftovers
Keep any leftover muffins in an airtight container at room temperature for up to 3 days. This helps maintain their moist texture and rich flavor without drying out.
Freezing
Freeze individual muffins in a sealed freezer bag or airtight container for up to 2 months. This way, you can enjoy a freshly baked taste anytime by simply taking them out to thaw or reheat.
Reheating
Reheat frozen or refrigerated muffins in a microwave for about 20 to 30 seconds or warm them in the oven at 325°F (160°C) for 5 to 7 minutes. This brings back their fresh-baked warmth and makes the peanut butter swirl gooey and irresistible again.
