I hope that you are not getting tired of chocolate recipes, because I have one more for you. Peanut Butter Stuffed Chocolate Cupcakes with Peanut Butter Frosting. And yes, they are as good as they sound. I experimented half a dozen times with the recipe (over the course of an entire year!), and finally came up with one that I think is simply amazing. The ratio of peanut butter filling to chocolate cupcake is just right, and they are melt in your mouth delicious!

I wanted to find a from scratch cupcake recipe that I loved, and I tried many, believe me! They were either too dry, to heavy, not dense enough to support the filling. . . etc. Then I tasted a chocolate cupcake at my cousin’s birthday party.
I knew it was a winner after one bite, so I got the recipe from her friend Jody, who is now my friend. 🙂 I like my chocolate cupcakes dense, moist, and fudgy, and these fit the bill. The cupcakes are great just plain with chocolate frosting, but stuff them with homemade peanut butter filling, and they become over the top amazing.

It is the perfect way to top off the chocolate cupcakes with the hidden peanut butter filling inside!

  1. Maybe could I use my new tool to remove a plug of cooled cupcake then fill with the filing and not cook the filling then frost?

  2. I have made these before with a slightly different recipe, but think I will try this one when I make them this time. To really send them way over the top, after I frosted them I put a Miniature Reese’s Peanut Butter Cup on the top of each one.

  3. Kara, I was thinking of maybe adding a bit of cream cheese to the filling, do you think if I added it that it would leak out of the cupcake when its baking?

  4. OMG, I used this peanut butter frosting recipe, and it is absolutely delightful!!! I did not change one thing about the recipe and the icing is perfect!!!

  5. it tastes good, but when baking it, the peanut butter filling was like lava coming out of the cupcakes, so most of the filling was lost 🙁

    • Dang, I didn’t have that problem with mine. Were your peanut butter balls thoroughly frozen? Maybe I need to tell people to freeze them for longer?

      I did freeze the peanut butter balls for a few hours, I think it may be that my oven was too hot. When next i try, I will lower the temp, and see how it goes. Thanks for sharing this lovely recipe 🙂

  6. wow these look great!

  7. These look so good Kara! I can’t wait to make some! Your pictures are so good too. 🙂

    How many cupcakes does this make?

  9. Oh my gosh Kara. Great minds must think alike because I just made peanut butter and chocolate cupcakes for my mom’s birthday this week (They’ll be up on my blog next week) Yours are different than mine however. I L-U-V the peanut butter filling inside the cupcake! It reminds me of peanut butter candy I used to get at the school cafeteria when I was a kid. YUM!!!

    • The peanut butter filling in the middle is my favorite part! It does taste like candy. 🙂 Can’t wait to see your recipe!
