I may never make regular Rice Krispies treats again. I’ve gone all-in on making these bake-sale goodies even better than the box with upgrades like toasting the cereal and browning the butter, but now that I’ve made this recipe, there’s no going back. Here, squishy-crispy Rice Krispies treats collide with peanut butter and chocolate for the ultimate Reese’s peanut butter cup dessert.
You start by adding a good dose of peanut butter to the marshmallow mixture. While you could stop there — and call these treats peanut butter scotcheroos — go ahead and sandwich a layer of full-size peanut butter cups between the peanut buttery, marshmallowy, crispy cereal mixture, and top it all off with melted chocolate. Once you try them, you’ll agree that these gooey, no-bake bars are even better than the original.
Why You’ll Love It
- It looks just like a Reese’s peanut butter cup. With peanut butter, chocolate, and candy layers, these no-bake bars look just like (or even better than) the original.
- They’re the best Rice Krispies treats you’ll ever have! Adding a layer of Reese’s peanut butter cups to the treats is delicious, but take it to the next level by mixing peanut butter into the marshmallow mixture and finishing with a layer of rich, melted chocolate.
Key Ingredients in Peanut Butter Cup Rice Krispies Treats
- Rice crisp cereal: This cereal gives the treats a satisfying crackle and crunch. Use slightly less cereal (5 1/2 cups instead of 6) to make sure these treats are extra-gooey.
- Mini marshmallows: Smaller, mini marshmallows melt more evenly than large marshmallows.
- Peanut butter: Add a 1/2 cup creamy peanut butter to the butter and melted marshmallows. Regular or no-stir natural peanut butter works best for this recipe.
- Reese’s peanut butter cups: Sandwich 16 full-size Reese’s peanut butter cups (from 8 packages) between layers of the peanut butter-marshmallow-cereal mixture.
- Chocolate chips: Microwave semi-sweet chocolate chips until almost completely melted, then stir until smooth. Substitute with peanut butter chips for extra-nutty flavor.

Nutritional Info
Ingredients
- 6 tablespoons
unsalted butter
- 1/2 cup
creamy peanut butter
- 1/2 teaspoon
vanilla extract
- 1/4 teaspoon
kosher salt
- 1 (10-ounce) package
mini marshmallows (about 4 cups), divided
- 5 1/2 cups
rice crisp cereal, such as Rice Krispies
- 16
full-size Reese’s peanut butter cups, 8 (1.5-ounce) packages
- 1 1/2 cups
semi-sweet chocolate chips (about 8 ounces)
Instructions
Line the bottom and two opposite sides of an 8x8-inch baking pan (about 2 inches high) with a sheet of parchment paper so that it hangs about 2 inches over the sides of the pan to form a sling.
Cut 6 tablespoons unsalted butter into 6 pieces and place in a large pot. Melt over medium-low heat, gently stirring with a flexible spatula so it melts evenly. Turn off the heat. Add 1/2 cup creamy peanut butter, 1/2 teaspoon vanilla extract, and 1/4 teaspoon kosher salt, and stir until combined and smooth.
Working quickly, add half 1 (10-ounce) package mini marshmallows, and stir until thoroughly melted. Add the remaining marshmallows and stir until melted. (Return the pot to low heat if the marshmallows aren’t melting easily, but keep a close eye on the butter, as you don’t want it to continue to brown to the point of burning.)
Add 5 1/2 cups rice crisp cereal and gently fold it in until the cereal is completely coated with the marshmallow mixture. Transfer half of the mixture to the baking dish and gently press into an even layer, pushing it into the corners with the spatula or buttered hands. Arrange 16 full-size peanut butter cups in a single layer over the cereal mixture. Top with the remaining cereal mixture and gently press into an even layer.
Place 1 1/2 cups semi-sweet chocolate chips in a medium microwave safe bowl and microwave in 30-second increments, stirring between each, until melted, 1 to 1 1/2 minutes total. (Alternatively, melt on the stovetop over low heat.)
Pour over the bars and spread into an even layer. Refrigerate until the chocolate is set, about 40 minutes. Grasping the excess parchment, transfer the slab to a cutting board. Cut into 16 pieces.
