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.

  • Stacy | Wicked Good Kitchen

    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!

    That’s one nifty little baking tool! I’m going to look for it here in Canada – love how it makes adding a ‘center surprise’ much easier :)

    • CrunchyCreamySw

      I hope you will find it and make some adorable surprise cupcakes! Thank you, Emily!

    • CrunchyCreamySw

      Thanks, Laura!

  • Colette

    I love surprises and anything OXO!

  • Allie|Baking a Moment

    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.

    • CrunchyCreamySw

      lol Well, than I say you should try these. :) I think you both will love them. And the eggless cupcake recipe is now my favorite. Let me know if you try it! I would love to hear what you think, Allie! Thank you!

      • Allie|Baking a Moment

        I certainly will! ;)

  • Sarah Younker

    I don’t have heavy whipping cream, could I use coffee creamer?

    • CrunchyCreamySw

      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!

  • Vera Zecevic – Cupcakes Garden

    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.

  • Lindsay

    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

      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

        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!

  • Susan Farndell

    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

      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!

  • CrunchyCreamySw

    Yay! Thanks!
