You will find pure bliss within each bite of these Reeses stuffed brownies. A fudgy brownie stuffed with Reese’s peanut butter cups and then topped with a creamy peanut butter frosting. Dangerously delicious!
I admit I am obsessed with peanut butter and chocolate, so these loaded brownies just hit my soul in a whole new way. For another peanut butter version, you have to try my Buckeye brownies. Or step out of the box and try my German chocolate brownies.
What Are Reese’s Stuffed Brownies
These brownies are just like they sound. You take a boxed brownie mix,, whip it up, stuff it with peanut butter cups, and bake it as directed.
Once baked and cooled, you spread on this thick, velvety, smooth peanut butter frosting. Then, top with extra chopped peanut butter cups and dive in.

Ingredients You Will Need
Brownies – I used boxed brownies to speed up the prep. You will also use all the ingredients needed on the back of the box.
Reese’s – Peanut butter cups are simply the star if this dessert. I reached for full-size Reese’s.
Peanut Butter—I wanted the frosting to be peanut butter-flavored, so I used creamy peanut butter as the base.
Butter—Use softened butter to help create a rich and velvety texture in the frosting.
Powdered Sugar—Powdered sugar is the thickening agent for the frosting. If you find clumps, sift it.
Heavy Cream—Add some heavy cream to the frosting to thin it out and help create a stunning creamy texture.
Vanilla – A splash of vanilla is used to help elevate the flavor of the frosting.
Variations and Substitutes
- You can swap the Reese’s peanut butter cups for a different type of chocolate—Snickers, Rolos, Twix, etc.
- Sprinkle some mini chocolate or peanut butter chips on the brownie mix for added sweetness.
- To elevate the flavor, drizzle the top of the frosting with caramel, hot fudge, or even chocolate sauce.
- You can crush pretzels or peanuts and sprinkle them over the frosted brownies, or you can mix them in the brownie batter before baking.
- Make this recipe with homemade brownies in replacement for a boxed brownie.
- You can skip adding the frosting if you prefer less in the brownies.
Tips For Making Reese’s Stuffed Brownies
Start with a prepared pan sprayed with cooking spray or even lined with parchment paper.
After you place Reese’s cups in the brownie mix, lightly press it down in the batter. Don’t push too deep enough to get them into the brownie mix.
These need to be baked a little longer than the box directions state; adding the peanut butter cups makes the brownies thicker, so added baking time is needed.
Watch the cooking time and make sure you do not overbake the brownies. When you stick a toothpick in the brownie mixture, your brownies are done, and it comes out clean of wet brownie batter.
Allow the brownies to cool before you frost them fully. Otherwise, the frosting will melt into the brownies.
Storing Brownies
You can store the brownies at room temperature for 3-4 days or refrigerate them for 6-7 days to extend their life.
The other option is freezing any brownies you do not plan to eat immediately. They can be frozen in a freezer-friendly container for up to 3 months. Then eat straight from the freezer or thaw on the counter or in the fridge overnight.
FAQs
Can I use homemade brownies instead of a boxed mix?
Yes, if you prefer a homemade brownie batter, go for it. Mix and bake as directed. I would add a couple extra minutes to the baking time to ensure the brownies thoroughly bake through.
Can I use mini Reese’s cups instead of full-sized ones?
Of course. You can use smaller Reese cups or chop them up and sprinkle in the brownie mixture. Just lightly press into the batter as you would the full size.
What can I substitute for heavy cream in the frosting?
Milk or even half-and-half can replace the heavy cream in the peanut butter frosting. It will reduce the richness of the frosting but work just as well.
