Peanut Butter Blossom Cupcakes

I looove peanut butter. As if you couldn’t tell. It’s just one of those things I will never ever in my whole life get enough of.

I’ve been planning to make these cupcakes for a while. The inspiration came from a momentous desire to make peanut butter frosting and from my English teacher, Mrs. Fleming, who’s in love with peanut butter blossoms. Thus, this Peanut Butter Blossom Cupcake was born!

I used the chocolate cake recipe from Betsy Eves aka Java Cupcake that I’ve also wanted to try for a few months. She claims it is the best chocolate cake she’s ever eaten, and it certainly does not disappoint. Many homemade cake recipes I’ve used have been at least slightly dry or just not the right flavor or texture compared to doctored boxed mix, but this cake was incredibly moist and intensely flavorful. It paired beautifully with the peanut butter buttercream, which I was sooo proud of! Frosting is my favorite part of any cake, both to eat and to make. It’s just so satifying when you make the perfect frosting.


First make the peanut butter blossoms. You can really use any recipe you want, and you will not need the full batch, depending on how big the recipe is. I recommend: Soft Peanut Butter Cookies, Vegan Peanut Butter Cookies, or Hershey’s Peanut Butter Blossoms. Do not bake the cookies yet!! Place the dough in the fridge to chill. Also, unwrap 14-18 Hershey’s kisses (one for each cupcake), and set aside.


The cake was quite fun to make, because I’ve never done it this way before. Melt butter in a medium saucepan and whisk in cocoa powder, espresso powder, coffee, and vanilla until combined. As usual, I tried to low-fat it a bit and used half butter half oil. Because of this, everything did not combine completely, but it worked out fine.

In a separate bowl, whisk sugar, flour, baking soda, and salt.

In another bowl, whisk the sour cream and egg. Hint: to substitute for 1/2 cup sour cream, use yogurt, or drop 1 1/2 tsp lemon juice or white vinegar into a measuring cup and fill the cup up to the 1/2 cup line with evaporated milk.

To the sour cream bowl- slowly add a few drops of the chocolate and whisk thoroughly. Then slowly add the rest of the chocolate mixture, whisking until completely combined.


In the flour mixture, make a well (a hole in the flour), and pour in the wet ingredients. Whisk until it is completely smooth.

Use a small ladle or cookie scoop to pour the batter into cupcake liners, until they are about 1/3 full. Then take out the cookie dough and drop 2-3 tbs dough using a tablespoon or cookie scoop into the center of the batter. Top each with a Hershey’s kiss, then cover with batter until the liner is 2/3 full.


Bake at 350 for 20 minutes (see my post on checking for doneness). Cool completely and frost!

I used peanut butter buttercream and a Ziploc bag, and made a swirly design on top. Because these cupcakes are beautiful inside and out.

  5. Make a well in the flour mixture. Pour the wet ingredients into the dry and mix until smooth, without any lumps.
  6. Using a ladle or cookie scoop, fill each liner 1/3 full.

  9. Bake about 20 minutes or until done (see tips on how to test for doneness).
  10. Cool completely and frost with peanut butter buttercream.
  11. Make cookies with remaining cookie dough or freeze to use later.

Peanut Butter Buttercream


  • 1 cup (2 sticks) butter
  • 1 cup peanut butter
  • 1 tbs vanilla
  • 2 cups powdered sugar
  1. Whip butter for 1-2 minutes until creamy.
  2. Add peanut butter and vanilla and whip until creamy.
  3. Slowly add powdered sugar a little at a time. Start at a low speed, mix until incorporated, then whip at a high speed. Repeat until the desired consistency is reached.

See my tips for buttercream and how to fill a piping bag.

Swirl frosting onto the cupcake, starting from the outside, and lifting the tip of the bag up in the middle.


Conclusions: The chocolate cake really did live up to its expectations. It gives an incredibly rich flavor and moist texture. I used French vanilla coffee, so the coffee flavor was detectable, but it added to the deliciousness. The cookie inside was a big hit, too, but the buttercream was my favorite part: silky and peanut buttery and amazing 🙂 The flavors work so well together and the whole cupcake is just a mini world of perfection.
