Why I Truly Think That This Is The Best Chocolate Peanut Butter Cupcakes recipe
These easy chocolate peanut butter cupcakes are a luxurious blend of rich chocolate and creamy peanut butter that will have you running back for seconds!
To make these chocolate cupcakes peanut butter flavored, I take my signature chocolate cupcake base and top it with my creamy homemade American buttercream infused with peanut butter. They offer the perfect balance of sweet and savory notes, thanks to the peanut butter and a hint of salt. The frosting's creamy, slightly less sweet flavor perfectly complements the moist chocolate base, creating a melt-in-your-mouth experience you won't forget!
Here, you will not find chocolate peanut butter cupcakes from cake mix. But, even though these are chocolate peanut butter cupcakes from scratch, they are still incredibly easy to make using simple, everyday ingredients and essential equipment. You can even get creative with add-ins, fillings, and toppings!
Katalin's key take on how to make cupcakes super moist
No one enjoys dry, crumbly cupcakes! However, achieving a perfect texture isn't a matter of luck. The secret to decadently moist chocolate cupcakes and peanut butter icing is using the right ingredients and techniques.
Baking is a science, so measuring accurately and choosing high-quality ingredients are essential for success. Using oil combined with eggs and milk creates incredibly soft cupcakes. Sugar also plays an important role, as it binds with the liquids to lock in moisture, while leavening agents like baking powder and baking soda work with acidic components to produce a light, airy texture.
In this chocolate peanut butter cupcake recipe, I've replaced the usual butter and buttermilk with oil and baking soda, ensuring every bite is moist—even after refrigeration!
Mastering the technique is just as crucial as choosing the best ingredients, so precision is key for consistently moist, tender cupcakes and irresistibly creamy, flavorful frosting. Use tools like a digital scale and thermometer to measure ingredients and temperatures accurately, follow the recipe exactly as written, and be careful not to overbake.

Ingredients
You only need a few simple pantry staples, such as oil, butter, sugar, flour, eggs, cocoa powder, milk, and of course, peanut butter to make this recipe. For a printable recipe card with exact ingredient quantities, visit the original Chocolate Peanut Butter Cupcakes recipe at Spatula Desserts.
The chocolate cupcake base comes together in seconds
Before starting the chocolate cupcake batter, the milk, coffee, and egg must be at room temperature to blend easily. To quickly bring your egg to room temperature, stick it in a bowl of warm water for 5-10 minutes.
Start by preheating your oven to 175℃ / 350℉ (no fan) and lining your cupcake tin with muffin liners.
Using an electric hand mixer, whip the wet ingredients (room-temperature egg, oil, both types of sugar, room-temperature coffee and milk, and vanilla extract) together for 1-2 minutes.
Sift the dry ingredients—the all purpose flour, baking powder, baking soda, cocoa powder, and salt—into the bowl. Please don't skip the salt; it balances the flavors!
Gradually combine the wet mixture with the dry ingredients, switching to a rubber spatula to gently fold them together until just mixed. Or, use your hand whisk for quicker emulsification, but make sure you stop as soon as the dry bits are incorporated into the wet ingredients. It should not take more than 30 seconds.
Using a spoon, ice cream scooper, or piping bag to evenly divide the batter among the cupcake liners, filling each about ¾ full.
Bake for 20-22 minutes or until a toothpick inserted in the center comes out clean. Be careful not to overbake, as this can cause dryness.
Before applying the frosting, let the cupcakes cool completely to room temperature on a cooling rack.
The secret to 'not too sweet' peanut butter frosting is: SALT!
Before starting the frosting, make sure your butter is at room temperature. Softened butter is critical to achieving the creamiest peanut butter buttercream. See my guide on softening butter quickly for tips on how to do so without using a microwave. Use unsalted butter only to keep from adding more salt to the recipe. You can also make your butter at home.
Cream the room-temperature butter with smooth, unsweetened peanut butter (do not use natural peanut butter) on medium-high speed for about 3 minutes until the mixture turns color light and becomes fluffy.
Gradually sift in the powdered sugar, one tablespoon at a time, mixing on low speed. Once incorporated, increase the speed to medium-high and whip for another 4 minutes until the frosting becomes light, fluffy, and increases in volume.
Last, mix in the vanilla extract, salt, and heavy cream, whipping for an additional minute until the frosting is smooth and silky.
At this point, the peanut butter buttercream frosting should have a perfectly fluffy, pipeable consistency. However, if it feels too thick, you can adjust it by adding one tablespoon of cream at a time. If it's too thin, mix in additional powdered sugar one tablespoon at a time.
Assemble the cupcakes and decorate
Transfer the peanut butter cream frosting into a piping bag fitted with a nozzle and apply the buttercream on top of each cupcake.
Then, finish by drizzling on melted chocolate and finely chopped peanuts, and enjoy!
Some flavor variation ideas to try next time you bake
If you're looking to switch things up with your chocolate peanut butter cupcakes, here are some tasty variations to try:
Swap out the chocolate cupcake base for a classic, moist vanilla cupcake base.
Instead of peanut butter, why not try a different nut butter? I have several delicious recipes:
Kick the flavor up another notch by folding in peanut butter chips or chocolate chips. Or, give your cupcakes some crunch and extra nutty flavor by mixing in chopped peanuts or other nuts such as pecans, walnuts, macadamia nuts, or almonds.
Add a delightful surprise to the middle by filling your cupcake with more creamy peanut butter, homemade caramel, or chocolate ganache. Check out my guide on filling cupcakes for step-by-step instructions on making chocolate peanut butter cupcakes with filling.
Instead of sticking with the usual peanuts and melted chocolate topping, try a drizzle of homemade caramel, mini peanut butter cups, or crushed peanut butter cookies.

Expert Tips
- For the best flavor and texture, stick to premium, high-fat ingredients. I recommend using 36% fat heavy cream, 82% European-style butter, and 3% whole milk.
- Since these are chocolate peanut butter cupcakes with cocoa powder, you will want to opt for 100% Dutch-process, unsweetened cocoa powder for a deep, rich flavor that isn't overly sweet.
- Never skip the coffee! Adding coffee enhances the chocolate flavor without adding a coffee flavor. Decaf coffee works as well.
- When whipping the buttercream, use the paddle attachment on your stand mixer to prevent unnecessary air bubbles and ensure a smooth, creamy frosting.
- If your buttercream separates, gently warm the exterior of the mixing bowl to soften the butter slightly and help restore its smooth consistency.
Some useful equipment to make these cupcakes
For the best results, always use a digital scale to measure your ingredients accurately and a digital oven thermometer to monitor the temperature.
An electric hand mixer is best for blending the wet ingredients, while a rubber spatula is necessary to fold in the dry ingredients without overmixing.
You will need a 12-cup muffin pan for baking and a cooling rack to let the cupcakes cool completely.
When decorating, a piping bag with a Wilton 1M nozzle tip is ideal!
