How to Make Reeses Brownies
PREP. Preheat oven to 350F. Line a 13×9-inch pan with foil or parchment and set aside.
BROWNIES. In a medium saucepan, melt butter over low heat. Stir in chocolate chips, and melt, stirring frequently. When there are no more lumps, remove from heat and stir in sugar and vanilla. Add the eggs one at a time, and mix until the mixture is smooth and glossy. Fold in the cocoa powder, salt, and flour, and mix until barely combined.
BAKE. Pour the mixture into the prepared pan and bake 30-35 minutes, or until a toothpick inserted one inch from the side of the pan comes out clean. Remove from oven and allow to cool completely.
FROSTING. When the brownies are cool, beat together the softened butter, peanut butter, powdered sugar, and vanilla. Add milk until the frosting reaches a smooth consistency. Spread the frosting over the cooled brownies.
TOPPING. Add the chocolate chips and butter to a small microwave bowl. Microwave at 50% power for 30-second intervals, stirring in between, until melted and smooth. Pour into a piping bag (or Ziploc bag), cut off a small corner of the bag, and drizzle the chocolate over the frosting. Sprinkle with the Reese’s candies. Let cool and set up before serving.
Kristyn’s Recipe Tips
- Melt the chocolate and butter slowly to avoid scorching.
- Do not over-mix once the flour is added. This will help keep the brownies fudg-y.
- Line the pan with parchment paper to aid in easy brownie removal. Let the brownies cool completely before frosting for clean layers.
- If you’re using a glass or ceramic dish, then you’ll want to add a few extra minutes.
- These brownies slice best when slightly chilled and when using a plastic knife.

Thank you Alicia from The Baker Upstairs for sharing this delish recipe!
This recipe was first shared May, 2018.
Made these for a Memorial Day get together. Everyone LOVED them!!
I will use a box brownie mix next time. The brownies stayed very gooey, which is fine, but super hard to cut and make pretty squares for serving.
Our guest didn’t mind the gooeyness, but I did…………
The flavors of chocolate and peanut butter was so rich and yummy!!
Will definitely make these again!
This is the best brownies I have ever eaten. It is easy to make and people raved about the taste
Yay! I’m so glad the brownies were a hit!
My family is huge on PB and chocolate, so I often make a very fancy peanut butter-brownie cake. When that’s too much work though, I look for a peanut butter brownie recipe. I’ve made several over the years, but we all agreed: this one is the Best. And yes, the brownies are rich, but not as over the top as some. A big keeper!
I’m so glad you all enjoyed the brownies!! Yay!
Awsome
Um you had me at “reese’s and brownies” Two of my very favorite desserts and combining them was bliss. They are definitely a sugar overload, but worth it for a special occasion treat.
