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.

A cupcake pan with liners filled with chocolate cupcake batter and a mini Reese's chocolate in the center of each cupcake, ready to bake.

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!

  1. This turned out horrible, I actually threw most of it away as it was unusable as a frosting. I followed the recipe, including type of peanut butter recommended, powdered sugar, etc., and it still turned out chunky/grainy like it was separating. No I did not use granulated sugar or “natural” peanut butter. I’m an experienced baker and I tried salvaging it, without success. Many of the comments mention that you need 2 sticks of butter, but unfortunately I did not read all the comments prior to making this, and made it with 1 stick (1/2 cup) as per recipe. Very disappointing. If you really need 2 sticks of butter, please update the recipe.

  2. Hello it looks like when making the peanut butter cupcakes you add two sticks of butter to make the frosting, but in the recipe it only calls for a half a cup so which is it please.

  3. 5 stars
    You need to change the recipe to 1 cup butter. Great recipe once you figure it out by reading the comments.

  4. Hi, I’m curious if the frosting for this recipe can be frozen or not. I’ve already made and frozen the cupcakes for Thanksgiving, so I would like to know if the frosting could be made ahead of time as well.

  5. I ended up using 2 sticks as it was quite dense and stiff (even with extra milk). With 2 sticks it was beautiful, light, fluffy, and delicious!

  6. 5 stars
    The cake is super delicious! However, I am confused because the recipe says 1/2 cup butter, but the video shows two 1/2 cup sticks. Which do you recommend?

  7. Should the peanut butter cups be frozen prior to putting into the batter before baking? I made two batches of cupcakes where the PB cups melted and made the cupcakes gooey. I was unable to get them out of the pan without the bottom collapsing. What do you do to get the frosting light and whipped? I followed the directions exactly and the frosting seemed more like a buttercream and a big gritty.
