I was contacted by a lovely blog reader a few weeks ago. She had a special request that I am excited to help her with. She told me that she had a fantastic recipe for Peanut Butter Cup Cupcakes, that she normally doesn’t give out! Her request? Could I please adapt them to be gluten-free? Well, she totally had me at peanut butter cup. That…and the fact that she was willing to share her top secret recipe! Why does she need to adapt this recipe to be gluten-free? Her cousin, whom she is very close to, recently needed to go gluten-free and loves her peanut butter cup cupcakes. She wants to make sure that he is still able to enjoy her cupcakes…sweet, no?
This is the original recipe for Peanut Butter Cup Cupcakes. I can absolutely understand why the are a favorite recipe…yum! They are so full of peanut butter. Peanut butter in the cake, peanut butter in the frosting, and that delicious peanut butter cup! If you like peanut butter, you will love these.
Peanut Butter Cup Cupcakes
- ½ cup butter, softened
- ¾ cup firmly packed brown sugar
- ½ cup sugar
- ½ cup creamy peanut butter
- 4 large eggs, separated
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- ¼ teaspoon salt
- 1 cup whole milk
- 24 chocolate covered peanut butter cups
Preheat oven to 350. Line 2 (12 cup) muffin pans with paper liners. In a large bowl, beat peanut butter, brown sugar, sugar, and peanut butter at medium speed until fluffy. Add egg yolks, one at a time, beating well after each addition. In a medium bowl, combine flour, baking powder and salt. Gradually add to butter mixture alternating with milk, beginning and ending with flour mixture, beating just until combined after each addition. In a medium bowl, beat egg whites at high speed with a mixture until stiff peaks form, gently fold beaten egg whites into butter mixture. Spoon batter into prepared muffin cups, filling two-thirds full. Place 1 chocolate covered peanut butter cup in center of each muffin cup, pressing down until edges of peanut butter cup are even with cupcake batter. Bake for 15-20 min or until edges of cupcakes are golden brown, let cool in pans for 10 minutes. Remove from pans, and cool completely on wire racks. Spread, or pipe, creamy peanut butter frosting over cupcakes.
Creamy Peanut Butter Frosting:
- 1 cup butter, softened
- 1 cup creamy peanut butter
- ¼ cup whole milk
- 1 teaspoon vanilla extract
- 6 cups confectioners’ sugar
In a large bowl, beat butter and peanut butter at medium speed with a mixer until creamy. Add milk and vanilla, beating until combined. Gradually add confectioners’ sugar, beating until smooth.
Coming soon…the gluten free version!!

I adore these. What a lovely Reeses surprise in the middle!
This frosting looks divine.
Thanks a bunch! After you emailed me I sent him the link for for this page and he was excited:) I can’t wait to make them for him, you’re a life saver!
hey becky, i’m confused. isn’t AP flour nOT gluten free? the recipe looks yummy but i wonder what to use for the GF flour portion. thanks!
Hi everyone!
Just to clarify…this is the original recipe that I was sent. My gluten-free adaption is coming soon! You’re going to love it!
These look AMAZING! It’s been a long time since I’ve put a PB cup in a cupcake.
OM-peanut butter heaven-G! <3
These look AMAZING! I’m sure they taste just as good. I know I will try making these….soon! What a great idea to put a Reese’s PB cup in the middle. I’ve done that with a SMORE but what a fabulous idea to put it in a cupcake too. YUM!
I LOVE Peanut Butter! I have made a similar cupcake to this, but put a mini cup in the centre of the cake….duh! Why didn’t it occur to me to use a full size version. Thanks for the wake up!
Oh I love the surprise of the Reese cup in the middle! Yummo!
I made these cupcakes for my daughter’s cupcake themed 1st birthday party and it was a HIT! A month later, I still get compliments on how good they were. So THANK YOU!
With your permission, I’d like to post the recipe on my blog, citing you of course.
Gianna,
Of course you may post them:-) I’m so glad you enjoyed them!
I just made these tonight and they are delicious! I am a big peanut butter/peanut butter cup fan, so these hit the spot. I am going to have to bring some over to the neighbors before my husband and I devourer the entire batch! =P
My only tip is to be sure to pipe the frosting. It could have been just me but the frosting is so thick it is difficult to spread (and make them look presentable). I am going to run out tomorrow and get a decorating kit to finish the icing. Otherwise, these are pretty close to perfection!
Thanks for posting!!
I made these last night and the cake was very spongey and not cakey. Could I have beaten the egg whites too much?
Hmmm, it’s hard for me to say Krista. I don’t think you would have over-beaten the egg whites. This cupcake does have a little bit different of a texture than typical but I would say for me it’s a little more dense than spongey. It’s the frosting that really sends these over the top:-) Hope you have better luck next time…thanks for the comment!
Hi, i was just wondering what size reese’s cup you use? Is it the big ones?
Yes, the regular size (big) peanut butter cups. It’s no wonder that these are so good:-)
Happy baking!
