Peanut Butter Surprise Chocolate Cupcakes #OXOGoodCupcake

Rich and decadent eggless chocolate cupcakes topped with fluffy peanut butter frosting. Oh, and there is a surprise inside!

peanut butter surprise chocolate cupcakes 1 Peanut Butter Surprise Chocolate Cupcakes #OXOGoodCupcakeOne of those perfect flavor combinations is for sure chocolate and peanut butter. You can take this combo and make any treat your heart desire and it’s guaranteed that everyone will love it.

Same with these cupcakes. Rich and moist chocolate cupcakes topped with fluffy peanut butter frosting. May I add the cupcakes are made with no eggs, like these minis. They are absolutely fabulous and quickly became my go-to chocolate cupcake recipe. It’s so easy to whip up and bakes beautifully. Domed, fluffy and rich in color and flavor.

I just swapped some of the butter for peanut butter and voila! Peanut butter frosting! So so easy! I promise! The heavy whipping cream makes it super smooth and fluffy and I wouldn’t recommend skipping it.

Oh but wait! I took this amazing treat even further! I used some of the frosting as a filling for the cupcakes!

These cupcakes are special as you can see. But that’s not because of the rich chocolate base or the fluffy mound of frosting. Not even because of the surprise hiding inside.

These cupcakes are special because they are Good Cupcakes. I partnered with OXO to spread the word about their Bake a Difference campaign. OXO will donate $100 to Cookies for Kids’ Cancer for this post and all of the other participants’ posts this month. As a woman and a mother, I think it’s a wonderful way to bring awareness to this important case. I encourage you to support it as well by purchasing OXO tools with stickers (like the one seen in a photo below) on OXO website as well as many of the large retailers.

  • 1 and 1/2 c all-purpose flour
  • 1 c granulated sugar
  • 1 tsp baking soda
  • 1 tsp salt
  • 1/3 c unsweetened cocoa powder
  • 1/2 c vegetable or canola oil
  • 1 c water
  • 1 tsp vanilla extract
  • 1 Tbsp apple cider vinegar
  • for the frosting:
  • 2 c sifted confectionars' sugar
  • 2 Tbsp unsalted butter, softened to room temperature
  • 1/4 c + 1 Tbsp creamy peanut butter
  • 1 tsp vanilla extract
  • 3 Tbsp heavy whipping cream


    to make the cupcakes:
  1. Preheat your oven to 350 degrees F.
  2. Line cupcake pan with paper liners. Set aside.
  3. In a medium mixing bowl, whisk together the dry ingredients (flour, sugar, soda, salt and cocoa).
  4. In another mixing bowl, whisk together the wet ingredients (oil, water, vanilla and vinegar).
  5. Add dry ingredients to wet ingredients and whisk together until smooth.
  6. Fill cupcake liners about 2/3 full.
  7. Bake cupcakes for 17 to 18 minutes or until the toothpick inserted in the center of each cupcake comes out clean.
  8. Cool in pan for 2 minutes.
  9. Transfer onto a cooling rack to cool completely before frosting.
  10. to make the frosting:
  11. With an electric mixer, beat sugar and both butters until crumbly.
  12. Add vanilla and cream and beat until smooth.
  13. Increase the speed to medium high and beat for 3 minutes until fluffy.
  14. Place in piping bag. Set aside.
  15. assembling:
  16. Use a cupcake corer or pairing knife to core the cupcakes.
  17. Fill the cupcakes with frosting.
  18. Use leftover frosting to decorate the top of the cupcakes.
  19. Decorate the cupcakes.
  20. Refrigerate leftovers.


The recipe makes enough frosting to decorate 18 cupcakes. Since this eggless chocolate cupcake recipe makes 12 regular size cupcakes, the amount of frosting was perfect to fill them inside and decorate the tops.

Disclosure: I have not been compensated for this post. OXO sent me baking tools to use in making these cupcakes and they are mine to keep. All opinions are 100% my own. I am participating in this campaign in support of the cause.

    Is the vinegar necessary? The one thing I don’t have in the house so I just wondered if I really need to go get some. Can anyone tell me what it does?

    • CrunchyCreamySw says

      Do you have lemon juice?
      The vinegar acts with soda and makes them fluffy and give them rich, reddish color. I think it’s worth it!

    I just made a double batch of these and the cake turned out amazing! Amazing, soft, moist! Love it! However, the frosting turned out rather dry/thick and I can’t figure out why. It was really hard to pipe into the center and frost the tops. I used the right amount of each ingredient and the butter was soft. Any tips for next time? Maybe slightly less sugar? Thanks for the recipes!

    • CrunchyCreamySw says

      Hi Lindsay! Thank you so much for trying the recipe! I am so glad you enjoyed it! I would recommend adding a little bit (a teaspoon at a time) of milk if the frosting seems too thick. Hope this helps!

      • Lindsay says

        Thanks! I will try that next time! I brought them to work to share and everyone loved them, thick frosting and all. I’ve bookmarked this recipe because I will definitely be making these again!

    Hi Anna,
    I’ve featured this peanut butter-chocolate goodness on my blog, hoping that you don’t mind, but if you do, please contact me and I’ll remove it. All the best.

    • CrunchyCreamySw says

      Hi Sarah! I have not used coffee creamer in frosting so I can’t tell you how it will affect the texture. I like the whipping cream as it will whip in the frosting. Thanks for asking!

    Ok, my hubby has been pestering me for pb chocolate cupcakes for weeks now! And the more you talk about your eggless recipe, the more curious I’m getting! I may have to get going on this one ASAP. And I did not know about OXO + Cookies for Kids’ Cancer. Terrific cause and I will be sure to keep a lookout for that sticker.

  5. Stacy | Wicked Good Kitchen says

    Anna, I think you created my favorite cupcake in the whole wide world! Seriously. Reese’s is my all-time favorite candy bar and I love everything chocolate and PB. Love the PB filling and frosting with butter, whipping cream and a hint of vanilla. The chocolate cake batter is the best, I agree! Have made it into cupcakes before and no other recipe compares. Sublime. Beautiful photos, too, girl! Pinning!
