Ingredient Notes and Substitutions

  • Sugar – You’ll need granulated sugar for the chocolate batter, then powdered sugar to make peanut butter frosting for the brownies.
  • Peanut Butter – I prefer the flavor of natural peanut butter, but use your favorite! No-stir varieties are easier to work with and will create a creamier frosting.
  • Chocolate Chips – These are getting melted down for an easy chocolate drizzle.

    Milk chocolate enhances the Reese’s flavor, but semisweet or dark would help tone down the overall sweetness of the dessert.
  • Peanut Butter Cups – Opt for the miniature kind — wrapped or unwrapped — when making this recipe.

    They’re a bit taller than full-sized cups and will hold their shape better in the batter.

    Chop them into quarters for the brownies, then halves or quarters to sprinkle on top of the frosted layer.

Tips for Making Brownies with Peanut Butter Frosting

  • Line Your Pan.

Using a layer of parchment paper not only prevents sticking, but you can lift the Reese’s brownies right out of the pan for easier slicing.

  • Use Quality Cocoa.

Not all cocoa powders are alike and each will create a different chocolate flavor.

Regular unsweetened is the most commonly used, but Dutch-processed is great for balancing all of the sweetness with a more bitter flavor.

  • Cut Some Corners.

If you’d like, you can easily use your favorite boxed brownie mix instead!

Just follow the directions on the box, then top with the chopped Reese’s and proceed with the recipe as directed.

Also, avoid any mixes that have chocolate syrup or fudge to mix into the batter or the texture won’t turn out quite right.

Kitchen Tools You Will Need

  • 9×13 Baking Dish – This set is one of my favorites! The 9×13 is perfect for casseroles, and the smaller size is awesome for making half a casserole recipe.
  • Stand mixer or large mixing bowl with hand mixer for whipping up the peanut butter frosting for brownies.
  • Whisk – These have held up for over 10 years and are still as good as the day I bought them. With 3 sizes there is a whisk for every job!
  • Offset Spatula – This spatula has so many uses and is perfect for smoothing the frosting on top of the brownies.

How to Make Peanut Butter Frosting for Brownies

The process really couldn’t be simpler! You will need to bring both the butter and cream cheese to room temperature before getting started.

Do this by unwrapping both, slicing them into smaller pieces, and letting them sit on the counter for about 30 minutes.

  1. Whip the cream cheese. Don’t rush the process! It takes about 3 minutes on medium to get it to the right texture.
  2. Add the powdered sugar. Reduce the speed to low until incorporated, then kick it back up to medium until light and fluffy.
  3. Mix in remaining ingredients. Add the peanut butter, salt, and vanilla and beat until creamy and well combined.

Reeses Brownies FAQ

How do you check brownies with a toothpick?

Insert the toothpick into the very center of the pan — in this case, avoiding any PB cups.

The toothpick should come out clean, meaning that it’s not coated with any wet batter.

You do, however, want there to be a few dry crumbs! If it’s completely clean, then your brownies will end up a bit dry.

Is there a way to make Reese’s brownies nut-free?

Technically, yes — though they won’t be Reese’s brownies anymore!

Replace the peanut butter cups with 1 cup of milk chocolate chips and omit the frosting. They won’t be as rich, but you’ll still end up with deliciously fudgy brownies.

Can I use hot fudge instead of chocolate chips?

I don’t see why not, but make sure the temperature isn’t too hot or it may melt the layer of frosting.

Storing and Freezing Frosting Brownies

While they should be fine at room temperature for a few days, brownies with peanut butter frosting should be kept covered in the refrigerator if you need to store them longer.

It’s also best to cut slices as you need them to keep them from drying out.

Reeses brownies also freeze really well. Wrap squares tightly with plastic wrap and place in a freezer-safe storage bag.

Store for up to 6 months in the freezer and defrost for 30 minutes before eating.

  1. Am I an evil person for wanting to put a scoop of homemade vanilla bean ice cream on that? I promise I'll do 100 extra crunches tomorrow 😉

  2. There are no words Donna! I need these for my next birthday. I could skip dessert for months if I knew this was coming to the table! The photos are amazing too!

  3. Oh, I love this and would love to have you figure out the dip at The Jalapeno Tree Mexican Restaurant. They will not let me know as it is a secret. But it has cilantro, butter, fajita seasoning in it. It is called Mexican Fajita Dip. Thanking you in advance.

  4. We just had this for dessert. It was declared the BEST EVER and is the request for all future birthdays dinners. I couldn't bring myself to pour yet more chocolate over the top, though!

  5. Is there a reason why the brownies need to go in the freezer before frosting them? Could I just let them cool naturally on a cooling rack and then frost them? We have no room in our freezer.

  6. Can I use regular peanut butter instead of natural peanut butter? I think I will make my blondie brownies instead of the chocolate one. Instead of the Reese’s cups, I will use the peanut butter ones.

  7. 5 stars
    This is my go to recipe for easy and delicious brownies with or without the frosting! They are delicious either way. My family loves bite size brownies so I make them often in a mini muffin pan and they do not last long at all!

  8. 5 stars
