Peanut Butter Cup Brownie Bites

Something came over me this year. It took me 30+ years, but I’ve finally discovered how truly amazing a chocolate and peanut butter dessert can be. I’ve always enjoyed the combination, but something happened this year and took my enjoyment and made it an obsession. I can’t get enough! A few months ago, I came upon a wonderful chocolate cupcake and peanut butter frosting recipe in Ina Garten’s cookbook, Barefoot Contessa at Home. The cupcakes were fantastic, but the frosting was TO DIE FOR. It’s a delicious recipe and so simple that I’m shocked cupcake bakeries around the world haven’t jumped on it yet. It is truly the smoothest, creamiest, peanut butteriest frosting I’ve ever had. So, I got to thinking and thought that if this amazing frosting was great on a cupcake, it might be even better on a brownie.

I decided to bake brownie bites in my mini muffin pan. I thought this would work for two reasons. One: The brownie/peanut butter frosting combo would probably be pretty rich and Two: Mini brownies don’t make me feel nearly as guilty! Two or three mini brownies can’t be nearly as bad as one big brownie, right? Right? Right. (wink, wink)

So, now it was onto the frosting. I am not kidding when I say this frosting is the easiest, quickest frosting I’ve ever made…and I’ve made a lot of frosting. You might have all of the ingredients on hand at any time. You can frost to your heart’s content in less than 5 minutes.

After you whip the frosting into shape, simply spread or pipe the it onto the brownie bites. The frosting is very soft, so you may want to refrigerate the brownie bites if you aren’t going to serve them right away. They stay fresh for a few days…if they last that long.

Peanut Butter Cup Brownie Bites
Recipe type: Dessert
Prep time: 
Cook time: 
Total time: 
Serves: 24
  • Brownie Bites:
  • 1 box of brownie mix, your choice.
  • mini cupcake wrappers
  • Peanut Butter Frosting:
  • 1 cup powdered sugar
  • 1 cup creamy peanut butter (I use Jif)
  • 5 Tbsp. butter, softened
  • ¾ tsp. pure vanilla extract
  • ¼ tsp. kosher salt
  • ⅓ cup heavy cream
  1. Make the brownies: Preheat your oven to 350*. Mix up your brownie mix according to the directions on the box. Place cupcake wrappers in a mini muffin tin. Spray the wrappers with nonstick spray. Spoon the brownie batter into the mini muffin wrappers, filling to just about the ¾ mark. Bake, at 350* for approximately 14 minutes, or until tops are puffed, cracked and look dry. Cool completely on a wire rack before frosting.
  2. Make the frosting: Using a heavy-duty mixer with the paddle attachment, mix together the powdered sugar, peanut butter, butter, vanilla and salt. Mix on medium-low until very creamy. Scrape the bowl down at least once. Add the heavy cream and beat on high until the mixture is light and smooth. Pipe or spread on the brownie bites.
  3. Makes approx. 2½ dozen brownie bites
  4. ENJOY!

  1. Yum! I think I will try these for Bunco this week…I will let you know how they go over with the girls 🙂

    • These were a hit at Bunco! In fact, they were the only thing that got eaten all night. I had some left over frosting, that I was just told goes great with apple slices…can’t wait to try it 🙂

  2. My mom made these last night for my sister’s jewelry party. They were a huge hit and soooo yummy. I’m going to make them again this weekend for Cora’s birthday party as well. I love that you are doing this blog. Everything you’ve ever made for any family get-together I’ve loved!

      • So I made these for the party, but as full-size brownie cupcakes (because that was the size of the Hello Kitty cupcake foils!) I thought that they were way too dense and they took a long time to cook, so I would recommend sticking with the mini-size, as you recommended. But the frosting was excellent.

  3. I can not WAIT to try these! May even make them for Sam’s up coming B-day (he doesn’t like cake-who doesn’t like cake?)

  4. These are the best. I made them for a girls weekend and they requested that I make 150 of them for a party this week! By far my favorite dessert!

  5. I recently celebrated a birthday and I thought, “this is it. This is my year. This will be the year I read a recipe completely before I go to the grocery store and not leave anything off of the list. This will be the year I read a recipe carefully before I make it.” Well, I was wrong. In two weeks time, I have already made a second trip to the store for an item and I screwed up this recipe. In my defense, I was making this at 10pm after work and I was reading it off of my phone and the print was really tiny! (Not a great defense, huh?) I needed a quick recipe for a bake sale the day after 2 12s at the hospital and this was screaming my name and everything was going well until the part about spraying the liners (the first step)… Needless to say, the paper didn’t peel off of the brownies. I figured out my problem before I frosted and had a box of chocolate cake mix in the cabinet so I did salvage it. That. frosting. is. awesome! Elvis Costello awesome. Thanks for another great recipe- maybe I’ll read the next one more carefully.
