Brownie Peanut Butter Cups

For a while now, I’ve been wanting to use muffin pans to make brownies. I found several recipes, but none I could really get excited about. Then, I found this one that features one of my favorite combinations: chocolate and peanut butter.

The brownies are prepared in traditional brownie fashion, but scooped into muffin tins like cupcake batter. Instead of the swirled chocolate/peanut butter chips, I used a combination of chocolate chips and peanut butter chips in the batter and also on top. I actually think I like the look of the different chips better than I would the swirled chips. Either way, they are sure to be fabulous.

Brownie Peanut Butter Cups are rich brownies filled with sweet, gooey peanut butter and chocolate. - Bake or Break

I really love the dollop of peanut butter in the center. I put the warm peanut butter in a zip-top bag, cut a corner off, and piped it inside. For an even more decadent treat, I think you could also pipe in some melted chocolate, creating a chocolate/peanut butter melty, gooey center.

We found these to be best served warm. The edges are nicely chewy and the inside soft and gooey. I wish I could find adequate words to express how good these really are. Quinn said that they are one of his favorite things I’ve ever baked. With almost ten years of my baking for him, I think that says it all.

Brownie Peanut Butter Cups

Prep Time: 25 minutes

Cook Time: 15 minutes

Yield: 12 brownies

Brownie Peanut Butter Cups


  • 3/4 cup granulated sugar
  • 1/4 cup unsalted butter, softened
  • 1 tablespoon water
  • 3/4 cup semi-sweet chocolate chips
  • 1 large egg
  • 1/2 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • 1/4 teaspoon baking soda
  • 1/2 cup peanut butter chips plus about 1/3 cup more for garnishing
  • 1/2 cup semi-sweet chocolate chips plus about 1/3 cup more for garnishing
  • 3/4 cup creamy peanut butter


Preheat oven to 350°. Spray or grease 12 muffin cups.

In a large microwave-safe bowl, combine sugar, butter, and water. Microwave on high for 1 minute or until butter is melted. Stir in 3/4 cup semi-sweet chocolate chips until melted. Stir in egg and vanilla extract. Add flour and baking soda, stirring until blended. Allow to cool to room temperature. Then, stir in 1/2 cup each peanut butter chips and semi-sweet chocolate chips. Spoon batter by heaping tablespoonfuls into muffin cups.

Bake for 13-15 minutes or until top is set and a toothpick inserted into the center comes out slightly wet. Place pan on wire rack. Centers of brownies will fall upon cooling. If not, tap centers with the back of a teaspoon to make a hole.

Place peanut butter in a small microwave-safe bowl. Microwave on high for 45 seconds, then stir. While brownies are still hot, spoon about a tablespoon of peanut butter into the center of each brownie. Top with semi-sweet chocolate chips and peanut butter chips. Cool completely in pan.

    The brownies look absolutely delicious! I want to reach out and grab the last picture… soooo good. I love chocolate and peanut butter… just made chocolate cupcakes with peanut butter frosting recently.

  2. Dayna May 8, 2008 Reply

    Hands down one of the best combinations ever.
    I think I’ve gained weight just by looking at that last gooey shot though. Yum!

    I love making brownies in muffin cups. It is just so much easier than dealing with a big pan and cutting. Plus, they pack better. Your brownies look absolutely amazing! So good!

  4. Silvia May 8, 2008 Reply

    wow wow wow…triple wow! they look like a muffin (i adore) they are brownies ( i adore) so combine get heaven!!!
    thanks for the great tip and stunning photos!!

  5. Hallie May 8, 2008 Reply

    I agree they look wonderful. Do you use regular size muffin tins or mini muffin tins? I’ve never though of using tins before but its a great idea…I’m going to try it next time I make brownies.

  6. This is a great idea–especially for someone like me who likes the corner pieces of brownies better than the pieces from the center of the pan.

  7. sharon May 8, 2008 Reply

    YUM! I saw these on Tastespotting and had to see more :) I love baking brownies in muffin tins but last time I used liners so it was more like a cupcake. Putting them directly in the muffin tin would sure end up in a better crust. I’ll have to try this soon!

  8. Katrina May 8, 2008 Reply

    I have tried brownies in muffin tins before and they always stick to the pan, but I think I’ve always used a box mix (shhh). I can’t wait to try this recipe! Your photography is divine!

  15. jennifer May 8, 2008 Reply

    Chuck, I’ll take one of those cupcakes, please!

    Dayna, it’s definitely one of my favorite combinations. Maybe in my top 3.

    Holly, it is much easier to make brownies this way. I can’t believe I haven’t done it before.

    Thanks, Silvia!

    Hallie, these were made in regular sized muffin tins.

    Oatmeal Cookie Guy, these are all about brownie edges. :-)

    Sharon, I debated using liners for these, but in the end I’m glad I didn’t. They came out cleanly and the edges were baked just right.

    Thanks, Katrina! Let me know what you think of them if you make them.

    DessertObsessed, I assure you that they do indeed exist. Or, at least they did before we ate a couple and gave the rest to my sister and her husband.

    jd, these are not the kind of thing that stays around long enough to be leftovers. 😉

    Thanks, bunny!

    vldreyer, that about sums it up!

    My Sweet & Saucy, thanks so much!

    megan, I completely agree. Yum!

  18. What a great idea to bake brownies this way! I love the crusty part best, so this is perfect for me. They look awesome!

  19. Katrina May 8, 2008 Reply

    I made these today and used the Swirl PB/Chocolate chips as that is what I had, I also used milk chocolate chips, just for the decor as I like milk chocolate and PB better, but I used semi-sweet for the brownies, and mine aren’t as pretty as yours, but they taste darn good. Will try to post my picture on my blog soon.
    Your pictures are just amazing, and these are delicious. The PB goo in the middle is amazing, too.

    Look at all of the chocolate and peanut butter chips in them!!! They look great!

  21. Jennifer, I just have to say, whenever I’m in the mood to bake some delectable homemade treats for myself, my husband and the kiddos, I always check Bake or Break before proceeding. You always have such great ideas, mouthwatering photos and the recipes are typically something I can whip up in a flash. My sweet tooth family thanks you and so do I!

    Oooo, I bet those are good served warm and gooey… with a scoop of vanilla ice cream too. I like the idea of adding a chocolate filling with the pb.

    RecipeGirl, I didn’t even think about ice cream. What’s wrong with me?!? :-)

  25. Nan (and Jim) May 9, 2008 Reply

    Yum, yum and more yum! These are best served warm. We even put some vanilla ice cream on the side as if the brownies were not sinful enough alone.

    Jennifer, these are great! Thanks for letting us try some of these. We have only one more left, so it will be interesting who will end up with it!

    Just… wow. Did the chocolate/peanutbutter chips stay well suspended in the batter? I’ve found in the past that they can sink too the bottom and burn, so I often use the mini chips or chop the chips up into finer pieces. These look delicious!

  54. jennifer May 21, 2008 Reply

    Thanks, Hilary. I’m glad you liked them, too!

    A, the chips didn’t sink to the bottom at all. This is a nice, thick batter so that helped.

    Hi, I just made these for a little party I’m going to tonight. They turned out fabulously, though I put the peanut butter on top instead of inside for the “peanut butter cup” effect. I’m going to warm them up right before serving, I think they’ll be a huge hit. Thanks!

    Stephanie, I’m sure they will be well received. Have fun!

  65. Lisa June 2, 2008 Reply

    My mouth is watering just looking at the pictures – simply brilliant! Just recently, I made brownies in mini muffin tins for a party and put a Hershey’s chocolate kiss in the center prior to baking. It comes out as a gooey center and will stay soft for awhile (they haven’t stayed on the plate long enough to find out exactly how long). However, I’m told that if they’re reheated for a few seconds in the microwave, the kiss melts again for that yummy melty chocolately goo we all love. I’m definitely going to try mixing with the peanut butter center and mixture of chips. Thanks!

  66. jennifer June 2, 2008 Reply

    Lisa, your brownies sound delicious! I re-heated these and that peanut butter center just got gooey all over again. Yum!

    I couldn’t wait until Sunday to make these. :) Also, I couldn’t wait until they were completely cooled down either. I love these!

    Would this recipe work with a mini muffin tin? I think I might add a little espresso powder next time (and by next time I mean tomorrow). I think it does wonders for the taste of chocolate.

    Thanks for a great recipe.

    I made these in a mini cupcake pan (sprayed with Pam, no paper liners). I got 40 brownies from 1 recipe, using only 1/2 cup total of peanut butter for the centers, and as many chips that would fit(about 6 to each brownie.) They were part of Father’s Day snack sampler I did up for work and were a huge hit!

    Made these last week and they were DELICIOUS. I had to send them with my hubbie to work because I wanted to eat all of them. We used the “peanut butter” (crushed honey roasted peanuts) from whole foods, and it totally made these. The slight crunchyness and saltiness of the peanut butter accented with the rich chocolate brownies. WOW!

    Ram, because these are not your traditional brownie presentation, I’d be reluctant to tinker with the recipe too much. These have to be able to hold all that filling and topping.

    I wish there were more instructions….. like, did you measure the chips you added to the batter or just toss some in? Did you bake the brownies with the chips on top or did you add them afterward while the brownies were still warm? I’d think baking the brownies with the chips on top would melt them?
