Chocolate Cupcakes with Peanut Butter Frosting

by Alli

Chocolate Cupcakes with Peanut Butter Frosting are probably my favorite cupcakes ever. Chocolate and peanut butter are a match made in heaven.

When referring to cupcake topping, do you say frosting or icing? I seem to always be switching between the two, so I googled it.

I’m glad I stuck to Chocolate Cupcakes with Peanut Butter Frosting. Seems I’m correct on this one! However you say it, we love cupcakes. Make sure to visit my best cupcake recipes

Here’s The Deal

“Icing is generally used to glaze pastries or cakes and tastes more sugary than frosting. The frosting is a thick, fluffy mixture, used to coat the outside of a cake.”

Now that we’ve got that national crisis settled, let’s talk cupcakes. A white back, one of my favorite preschool teachers asked me to bake cupcakes for her preschool class at church.

Yep, she’s a teacher at one of the local schools and at church. The kids love her and so do I! So, I was happy to supply her classroom with cupcakes. 

Chocolate Cupcakes with Peanut Butter Frosting is my go-to cupcake recipe! Delish!

There was a time when I was a cake mix snob. You would never, ever catch me using a boxed mix. I turned my nose up at those prepackaged boxes when I passed them by at the grocery store. But sometimes a boxed mix comes in handy.

Ingredients For Chocolate Cupcakes With Peanut Butter Frosting

You can find the printable recipe card at the end of this post.

  • chocolate cake mix (plus ingredients listed on the box)
  • pure vanilla extract

Frosting Ingredients 

  • butter
  • peanut butter
  • pure vanilla extract
  • heavy whipping cream
  • powdered sugar

Helpful Hint: Powdered Sugar and Confectioners Sugar is the same thing. Basically, powdered sugar is granulated white sugar that has been finely ground and mixed with a little cornstarch. You can easily make powdered sugar at home.

I always add a teaspoon of pure vanilla to make a cake mix taste like homemade. You can get my homemade vanilla extract recipe here. It’s so easy to make your own vanilla.

When it came time to bake the cupcakes, I had symptoms of a cold and was feverish, so I resorted to a boxed mix, lots of handwashing, and made the frosting from scratch.

I guess I was a little delirious because halfway through the baking time, I realized I had done something I’ve never done before! I had left out the eggs – all three of them! Yikes! I just knew I’d have to redo the cupcakes!

Alas, when the baking time was up, the cupcakes looked great. So I asked my daughter and husband to eat one and they both proclaimed them delicious.

Then I remembered those recipes that call for a cola and a cake mix and realized I didn’t need the eggs at all. But, usually, I do add the eggs.

That revelation caused me to look back and remember all the times I didn’t bake a cake because I was out of eggs. Dang.

I added nothing in place of the eggs because it was an oversight. The crumb of the cupcakes looked normal and tasted as good or better than when I add eggs.

The cupcakes didn’t fall apart. Actually, they were perfect. Go ahead and leave those eggs out if you don’t have eggs on hand. I’ll never tell!
