These Reese’s Peanut Butter Cupcakes are always a crowd favorite! Chocolate cupcakes with peanut butter frosting and a Reese’s chocolate baked in the center.

It’s been really difficult writing this post, editing the pictures and getting it ready to share with you guys. It’s been a constant reminder that ALL I WANT is another one! Or two. Or three.

I’ve been dreaming of them ever since I made them.  Chocolate Cupcakes with Peanut Butter Frosting and a mini Reese’s chocolate baked in the center. BEST CUPCAKES EVER! You can never, ever go wrong with chocolate and peanut butter.

Use a standard muffin pan and place a muffin liner in each muffin cup. Fill with chocolate cupcake batter until each liner is half full. Place a Reese’s peanut butter cup in the center of each cup filled with batter. Now your cupcakes are ready to bake! Be sure to allow them to cool completely before frosting.

When your guests are ready to eat one they’ll find a happy suprise in the center: a Reese’s chocolate!

The peanut butter frosting is the really winner with these cupcakes and it couldn’t be easier to make.

How to make peanut butter frosting:

My biggest tip for making peanut butter frosting is to use a commercial brand of peanut butter, NOT natural or homemade peanut butter! I recommend Skippy of Jif. If you use a different kind of peanut butter you may experience separating, oily or texture issues.

Start by using an electric mixer to mix together the butter and peanut butter until completely smooth.

A clear mixing bowl with two sticks of butter and one and a half cups of peanut butter, next to another photo of the same mixing bowl with the butter and peanut butter mixed together until smooth.

 

Add the powdered sugar, vanilla and milk and mix again until smooth. The butter/powdered sugar/milk ratio here always yields a perfect thick and smooth frosting for me. If you’d like it a little thicker add a bit more powdered sugar, or if you’d like it thinner, add an extra splash of milk.

Powdered sugar added to a clear mixing bowl with creamed butter and peanut butter next to another photo of the same mixing bowl with the powdered sugar mixed in to make peanut butter frosting.

Once the cupcakes have cooled, frost them with the peanut butter frosting.  I used a Wilton 1M decorating tip and an Ateco decorating bag to frost these cupcakes, but you could even use a plastic ziplock bag with a small hole snipped from the corner to pipe the frosting on.

*Disclaimer….these cupcakes are made using a cake mix (gasp!). Here’s the honest truth. As much as I totally believe in cooking everything from scratch (here’s my favorite homemade chocolate cupcakes recipe) I believe there is a time and a place for boxed cake mixes. I “doctor” cake mixes all the time–I change the add-in’s so that the end result tastes like they’re from scratch!

Sometimes you only have 5 minutes to throw together a treat, and the batter for these cupcakes only takes that long! And the best part is no one will ever guess (or care) that you used a cake mix!

  • Store leftover cupcakes, covered, in the fridge for 3-4 days.

Notes

*Chocolate Cupcake From Scratch: These cupcakes are made using a cake mix (gasp!). Here's the honest truth. As much as I totally believe in cooking everything from scratch, I believe there is a time and a place for boxed cake mixes. I "doctor" cake mixes all the time--I change the add-in's so that the end result tastes like they're from scratch! If you prefer a "from scratch" version, follow this recipe!
Make Ahead Instructions: The cupcakes and the frosting can both be made ahead of time. Allow cupcakes to cool completely, then place in an airtight container and keep at room temperature for up to one day.
Freezing Instructions: Allow cupcakes to cool completely, then store unfrosted cupcakes in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator and bring them to room temperature before frosting and serving.

    Wow!!! Thank you so much for this fantastic recipe. What a crowd pleaser and delicious to boot😊 I used a “devils food” cake mix as the base but man the frosting is the best peanut butter frosting ever!

  2. 1 1/2 cups of peanut butter made my icing extremely thick and tasted too much like pbutter. I added more powdered sugar but couldn’t get the consistency of frosting. And it certainly was dark like pnut butter. Certainly not like the picture. I added the vanilla and milk and was very thick and pnut buttery..

      SOOO I tried a second time and it came out perfect. I neglected to mix the butter with the peanut butter as instructed and I had to start over. Once I followed direction it came out fantastic!

  4. Love this frosting recipe. This is my son’s new favorite and I am making it for the second time by request. I used a gluten free cake mix because of allergies and it was a hit. Thank you!

  5. I have had so many raves on these cupcakes & frosting but we all can’t get enough of the peanut butter frosting!! So good!!!
