Today’s Reese’s brownies have a rich and luscious chocolate brownie layer, topped with a delicious peanut butter buttercream, then they are drizzled with even more chocolate and sprinkled with chopped Reese’s candies.

Desserts just don’t get better than that!

To mix things up we may even try a blondie base next time and top it with white chocolate Reese’s and a white chocolate drizzle. We are thinking that would be an amazing version as well. 😉

It’s hard for us NOT to love the chocolate and peanut butter combo and these brownies are the epitome of Reese’s heaven. They remind us of our famous Buckeye Brownies, but I’m pretty much thinking these treats are tied. They both are heavenly!

How to Make Reeses Brownies

PREP. Preheat oven to 350. Line a 13 x 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.

Variations + REcipe Tips

I LOVE LOVE LOVE Chocolate desserts. Add some peanut butter and you’ve got a slice of heaven. This dessert is so delicious as it is however, the great thing about being a baker is being a little creative. You can easily create different candy bar variations such as:

  • Chopped Snickers or Butterfinger
  • Reese’s Pieces or chopped Peanut Butter M&M’s
  • Add a caramel layer between the peanut butter and chocolate layer.

Using room temperature eggs will help them incorporate better.

Use high quality ingredients. It really makes a difference!

Line the pan with parchment paper to aid in easy brownie removal.

If you’re using a glass or ceramic dish, then you’ll want to add a few extra minutes.

Storing Info

I have to admit these are decadent and I can only eat a small piece which is good since it has a higher calorie count. So the fact that these store well is great because we can have a sweet treat now and then save the rest for later. 

  • For short term storage you can STORE the brownies in an airtight container for 3-4 days before they start drying out. 
  • For longer storage I place each brownie in a fold top sandwich baggie and then place them together in a Freezer Ziploc. FREEZE for up to 3 months.

  1. The brownie recipe for the Reeses brownies has a typo…2/3 flour and then 1/3 flour….think one of those should be cocoa powder…thanks

    These brownies were divine, they were so full of flavor and easy to make. We enjoyed them this evening with ice cream and it was the perfect dessert!

    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.
