Ingredients You’ll Need
These simple yet essential ingredients come together beautifully to create cupcakes bursting with flavor and just the right texture. Each ingredient plays a special role, from the cocoa powder that gives a deep chocolate richness to the smooth peanut butter lending the frosting a velvety finish.
- 1 and 1/3 cups all-purpose flour: The backbone for a tender yet sturdy cupcake crumb.
- 1/3 cup unsweetened cocoa powder: Provides that unmistakable chocolate depth without extra sweetness.
- 1 tsp baking powder: Helps the cupcakes rise beautifully and stay light.
- 1/2 tsp baking soda: Adds extra lift and creates a soft texture.
- 1/4 tsp salt: Enhances the chocolate and peanut butter flavors by balancing sweetness.
- 1/2 cup unsalted butter, softened: Key for moisture and a rich mouthfeel in the cake and frosting.
- 3/4 cup granulated sugar: Sweetens without overpowering the chocolate and peanut butter.
- 2 large eggs, at room temperature: Bind everything together and add structure.
- 1 tsp vanilla extract: A little warmth and complexity to deepen flavor.
- 1/2 cup buttermilk, at room temperature: Creates a tender crumb and adds subtle tanginess.
- 1 cup creamy peanut butter: The star ingredient of the frosting, creamy and rich.
- 2 cups powdered sugar, sifted: Ensures smooth, silky frosting without lumps.
- 1/4 cup heavy cream or milk: Adjusts frosting consistency for perfect spreadability.
- Mini Reese’s peanut butter cups, chopped (optional): Adds a delightful crunchy garnish and extra peanut butter punch.
How to Make Chocolate Peanut Butter Cupcakes Recipe
Step 1: Preheat and Prepare
Get your oven warmed up to 350°F (175°C) and line a muffin tin with cupcake liners. This sets the stage for perfectly baked cupcakes that come out cleanly and with a lovely presentation.
Step 2: Mix Dry Ingredients
In a medium bowl, combine the flour, cocoa powder, baking powder, baking soda, and salt by whisking them together. This ensures even distribution of leavening agents and cocoa, creating consistent taste and texture throughout each cupcake.
Step 3: Cream Butter and Sugar
In a large bowl, beat together softened butter and granulated sugar until the mixture is light and fluffy. This step is crucial as it incorporates air, giving the cupcakes their tender crumb and helping them rise beautifully in the oven.
Step 4: Add Eggs and Vanilla
Add the eggs one at a time, making sure to beat well after each addition to fully incorporate them. Then mix in the vanilla extract, which adds a lovely depth and enhances the chocolate and peanut butter notes.
Step 5: Combine Wet and Dry
Gradually add the dry ingredients to the butter mixture, alternating with the buttermilk. Start and end with the dry ingredients. Mix just until combined to avoid overworking the batter, which keeps the cupcakes light and fluffy.
Step 6: Fill the Liners
Divide the batter evenly among the cupcake liners, filling each about two-thirds full. This filling amount allows the cupcakes to rise without overflowing and ensures a perfectly shaped dome.
Step 7: Bake to Perfection
Bake in the preheated oven for 18 to 20 minutes, or until a toothpick inserted into the center comes out clean. This signals that the cupcakes have set and are ready for cooling.
Step 8: Cool Completely
Remove the cupcakes from the oven and let them cool for 5 minutes in the pan before transferring to a wire rack. Cooling cupcakes fully before frosting prevents the frosting from melting and sliding off.
Step 9: Make the Peanut Butter Frosting
Beat together softened butter and creamy peanut butter until smooth and creamy. Gradually add powdered sugar, alternating with heavy cream or milk, to achieve your desired frosting consistency. Mix in vanilla extract for that extra flavor boost.
Step 10: Frost and Garnish
Once the cupcakes are completely cooled, spread or pipe the peanut butter frosting onto each cupcake. For an extra special touch, sprinkle chopped mini Reese’s peanut butter cups on top. This adds a delightful crunch and accentuates the peanut butter flavor beautifully.
How to Serve Chocolate Peanut Butter Cupcakes Recipe

Garnishes
Sprinkling chopped Reese’s peanut butter cups adds a playful visual and textural contrast that makes the cupcakes irresistible. You could also try a dusting of cocoa powder or a few mini chocolate chips to elevate the presentation further.
Side Dishes
These cupcakes pair wonderfully with a cold glass of milk or a hot cup of coffee or tea, balancing sweetness with refreshment. For a more decadent dessert spread, serve alongside vanilla ice cream or fresh berries to add a bright, juicy contrast.
Creative Ways to Present
Transform your cupcakes into a centerpiece by presenting them on a tiered dessert stand or serving plate. Wrap each cupcake in colorful liners or tie delicate ribbons around cupcake wrappers when serving at parties for a festive touch that delights guests before the first bite.
Make Ahead and Storage
Storing Leftovers
Keep uneaten cupcakes in an airtight container at room temperature for up to two days. If your kitchen is warm, refrigerating them is a better option to maintain freshness, though bring them to room temperature before serving for optimal flavor and texture.
Freezing
You can freeze unfrosted cupcakes for up to three months. Wrap each tightly in plastic wrap and place them in a freezer bag or container. For frosted cupcakes, freeze first without garnishes, then thaw and add fresh toppings before serving to keep garnish texture intact.
Reheating
If you refrigerate or freeze your cupcakes, a few seconds in the microwave (about 10-15 seconds) brings back that just-baked softness. Avoid overheating, as that can dry out the cupcake or melt the frosting too much.
FAQs
Can I substitute natural peanut butter in this Chocolate Peanut Butter Cupcakes Recipe?
Yes, you can use natural peanut butter, but since it’s typically less sweet and more oily, you might want to adjust the sugar in the frosting slightly and ensure it’s well-stirred before mixing to keep a smooth texture.
What is the best way to store these cupcakes to keep them moist?
Store the cupcakes in an airtight container at room temperature for 1-2 days or refrigerated for longer storage. Adding a slice of bread in the container can help keep them moist by maintaining humidity.
Can I make the batter ahead of time?
For best results, bake the cupcakes immediately after mixing the batter. Though you can refrigerate the batter for a few hours, it’s ideal to bring it back to room temperature and gently stir before baking to ensure even texture.
Are these cupcakes suitable for kids?
Definitely! These Chocolate Peanut Butter Cupcakes are kid-friendly favorites. Just be cautious if serving to children with peanut allergies and consider an alternative frosting if needed.
How can I make the frosting lighter?
To lighten the peanut butter frosting, try folding in some whipped cream or reducing the powdered sugar slightly. This keeps it fluffy and less dense, making for an even more delightful topping.
