How to Make Peanut Butter Chocolate Cupcakes — Step by Step
Step 1: Preheat the Oven
- Preheat the oven to 350°F (175°C).
- Line a 12-cup muffin tin with paper liners.
Step 2: Prepare the Batter
- In a large bowl, sift together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
- Add the vegetable oil, buttermilk, eggs, and vanilla extract.
- Mix just until smooth and combined. The batter may be slightly thin — that’s normal.
Step 3: Fill the Cupcake Liners
- Divide the batter among the liners, filling each about 2/3 full.
- Tap the pan gently to release any large air bubbles.
Step 4: Bake
- Bake for 18–20 minutes, or until a toothpick inserted into the center comes out clean.
- Cool the cupcakes in the pan for 5 minutes, then transfer to a wire rack to cool completely.
Preparing the Peanut Butter Filling
Step 5: Make the Filling
- In a medium bowl, beat together the creamy peanut butter, powdered sugar, and milk until smooth and fluffy.
- Transfer the mixture to a piping bag fitted with a large round tip for easy filling and frosting.
Step 6: Fill the Cupcakes
- When the cupcakes are cool, cut a small circle from the center of each one (save the removed piece for a quick snack).
- Pipe the peanut butter filling into the cavity until just level with the top.
Frosting and Garnishing
Step 7: Finish the Cupcakes
- Pipe a generous swirl of the peanut butter mixture on top of each cupcake for a creamy frosting.
- Drizzle with melted chocolate for contrast and added richness.
- Top each cupcake with a mini peanut butter cup for a decorative, tasty finishing touch.
Pro Tips for the Best Results
- Room-Temperature Ingredients: Let eggs and buttermilk reach room temperature for a smoother batter and better rise.
- Mix Gently: Overmixing can make cupcakes dense — stir until the ingredients are just combined.
- Peanut Butter Options: If using natural peanut butter, stir well to reincorporate oils and avoid graininess.
- Make Ahead: Bake the cupcakes a day ahead and store unfrosted in an airtight container; add filling and frosting before serving.
- Variations: Try filling with Nutella or chocolate ganache, or add a sprinkle of chopped peanuts for texture.
Best Ways to Serve
- With Coffee: These cupcakes pair beautifully with a bold cup of coffee.
- As a Party Centerpiece: Arrange on a tiered stand for a polished dessert table display.
- With Ice Cream: Serve alongside vanilla ice cream for an indulgent treat.

FAQs — Peanut Butter Chocolate Cupcakes
Can I use crunchy peanut butter instead of creamy?
Yes. Crunchy peanut butter adds texture to the filling and frosting, though creamy peanut butter yields a smoother finish.
How can I make these cupcakes gluten-free?
Swap the all-purpose flour for a 1:1 gluten-free baking mix designed to replace flour cup-for-cup.
Can I prepare these ahead of time?
Absolutely. Bake and cool the cupcakes, store them unfrosted, and add the filling and frosting the day you plan to serve for the freshest result.
