These chocolate peanut butter cupcakes are made with a moist chocolate cupcake and fluffy peanut butter frosting. Add chocolate ganache and a peanut butter cup on top for the ultimate chocolate and peanut butter dessert!
Chocolate Cupcakes with Peanut Butter Frosting
I made these chocolate peanut butter cupcakes for my husband’s birthday over the summer and they were a huge hit! It’s no secret that chocolate and peanut butter are an award winning combination and these are the prime example of that.
The chocolate cupcakes with peanut butter frosting use my chocolate cupcakes from cake mix as the base then they are topped off with a creamy, nutty and sweet peanut butter frosting to make each bite absolute perfection.
Ingredient Notes
Find the full printable recipe with specific measurements below.
- Chocolate cupcakes: To make it easy I used Devil’s food cake mix, dry instant chocolate pudding mix, chocolate chips, eggs, canola oil and sour cream.
- Butter: Unsalted butter is best so that the frosting isn’t too salty.
- Peanut butter: A creamy peanut butter such as Jif or Skippy will give the frosting the best consistency. I don’t recommend using a natural drippy nut butter.
- Heavy cream: Used to thin out the frosting if needed. Milk also works.
- Garnish (optional): Add a drizzle of melted chocolate or chocolate ganache on top of the frosting, then top with a Reese’s peanut butter cup, chopped peanuts or a buckeye candy.
How to Make Chocolate Peanut Butter Cupcakes
Pour the dry cake mix and chocolate pudding mix into a large bowl and give it a quick whisk. Mix in the chocolate chips, then add in the eggs, canola oil and water. Add the sour cream and stir just until combined. Then pour the batter into cupcake liners about 3/4 of the way full.
Bake at 325°F for about 20 to 25 minutes. Use a toothpick to test if the cupcakes are ready. Remove from oven and let cool on a wire rack.
While the cupcakes cool, prepare the peanut butter buttercream. Beat the softened butter and nut butter with a handheld electric mixer (or stand mixer with paddle attachment) until smooth and fluffy, then slowly mix in the powdered sugar and vanilla. If the frosting is too thick, use the heavy cream to thin it out.
Once cooled, pipe the peanut butter frosting over the chocolate cupcakes and add any desired decorations on top.
Tips and Variations
- Piping the frosting. If using a 1M frosting tip with a piping bag, you want the consistency to be thick enough to hold a point. If you find that the consistency is a little too thin, add a bit more powdered sugar to thicken it up. Learn tips for how to frost the perfect cupcakes.
- Prevent sinking. Mix the chocolate chips in with the dry ingredients to prevent them from sinking to the bottom.
- Do not over mix the batter. Mix just until combined, so the cupcakes stay soft and moist.
- Make cupcakes from scratch. Instead of a boxed cake mix recipe make this completely homemade by using my chocolate cupcakes from scratch.
- Reese’s peanut butter cupcake recipe: For an extra boost of peanut butter flavor, you can add a miniature Reese’s peanut butter cup in the center of the cupcakes. Fill the cupcake liners halfway with batter, then add the Reese’s cup, then pour the remaining batter on top until 3/4 of the way full.
Storage
- Store: Store peanut butter chocolate cupcakes in the refrigerator for up to 1 week. Make sure to tightly cover the frosting with plastic wrap so that it stays soft and fresh.
- Freeze: I recommend freezing the unfrosted cupcakes and then adding the frosting after thawing. Wrap the cupcakes tightly in plastic wrap and store in the freezer for up to 3 months. Let thaw in the fridge overnight, then frost and enjoy!

One of our faves too! Thanks for your review :D
These are fabulous! My whole family loves the choc & pb combo, we are in cupcake heaven!
I am so happy to hear they were a hit with your family!
Peanut butter and chocolate really is the best flavor combo! These kind of desserts go in a flash in our home. I like to sub some of the butter for cream cheese to have a bit more tang in the frosting. YUM!
Mmm that sounds so delicious!
The kids insisted on making these last night and it was the best idea! So great!!!
I’m so happy they were a hit!
I don’t make many comments on food because I am very picky. However, I need to leave a comment for these cupcakes. These cupcakes were not that much work and turned out excellent. They were moist and the frosting was great too. Easy to do, great tasting and a great presentation (I used mini peanut butter cups for decor). Great recipe
I’m so glad you liked these cupcakes! I need to make them again soon! Thanks for your comment Jennifer. :)
These are a new favorite! Chocolate and peanut butter are my weakness!!
My mom LOVES Buckeye Balls, so the cupcake version is probably going to be her favorite thing ever! I’ll have to make these for her the next time I’m home!

I just need to accept the thought that my diet is ruined, don’t see another way. I’m making these tonight, the boys will be thrilled to finally see some sweets in the house. I’ve been on a diet the past couple of weeks and I can’t look at sweet things and not have any… Well, life is short, right? XD
You have a Pinterest account? Can I stalk you? XD
