How to Make Chocolate Peanut Butter Muffins

Follow these seven steps for moist muffins with bakery-style domes. The full recipe card with precise measurements is available below.

1. In a medium bowl, whisk together the flour, cocoa powder, granulated sugar, baking powder, baking soda, and salt. Set aside.
2. In a larger bowl, whisk the eggs, buttermilk, vegetable oil, and vanilla extract until combined.
3. Gradually add the dry ingredients to the wet ingredients, mixing just until combined. The batter will be thick.

4. Cover the bowl with a towel and let the batter rest for 15 minutes while you preheat the oven to 425ºF (220ºC).
5. For bakery-style domes, line a 12-cup muffin pan with six liners, filling every other cup. Scoop about 2 tablespoons of batter into each liner for the initial layer.

6. Microwave the peanut butter briefly until slightly melted. Drop 1/2 tablespoon of peanut butter into each cup and swirl with a toothpick. Add another 4–6 tablespoons of batter to cover, then top each muffin with another 1/2 tablespoon of peanut butter and swirl again.

7. Place the pan in the center of the oven and bake at 425ºF (220ºC) for 7 minutes. Without removing the pan, reduce the oven temperature to 350ºF (180ºC) and bake 12–14 minutes more, or until a toothpick inserted in the center comes out clean. Let muffins cool in the pan. Repeat with the remaining batter, bringing the oven back to 425ºF for the first stage of the next batch.

How to Create Bakery Style Muffins

To get tall, domed muffin tops, apply the following techniques when making the batter and baking the muffins.

1. The Rest Period

Let the batter rest for 15 minutes after mixing. During this time, the flour absorbs liquid and the batter thickens, which helps produce a higher rise in the oven.

2. Fill Every Other Muffin Cup

Using only every other cup in a 12-count pan prevents muffins from spreading into each other and encourages upward rise and even browning, giving you a bakery-style dome.

3. Fill Them To The Top

Fill liners to the top with batter. This may feel counterintuitive, but it helps the muffin gain height and form a domed top.

4. Bake at High Temperature Initially

Start baking at a high temperature (425ºF / 220ºC) for a short time to set the outer edges while the interior rises. Then reduce the temperature to finish baking through without overbrowning.
