These chocolate peanut butter cup s'mores brownies are insane! Packed full of deep chocolate flavor and TONS of peanut butter. Who can resist s'mores?

I’m going to warn you. This dessert is really not necessary. I originally set out to make basic s’mores brownies and somehow cut up reese’s peanut butter cups and drizzled peanut butter ended up on top. Not necessarily a bad thing, but if you’re counting calories I would stay far far away. How does it taste you ask?

Amazing! I should warn you that it’s extremely rich so try to keep the pieces small…if you can stand not eating the whole pan at once 🙂 Also the brownie is not overly sweet because I wanted a nice chocolaty dense brownie to hold up to all the toppings. Enjoy!!!

Yield: 8x8 pan

Prep Time: 35 minutes

Cook Time: 70 minutes

Total Time: 1 hour 45 minutes


For Crust:

  • 6 tablespoons unsalted butter - melted
  • 1-1/2 cups crushed graham cracker crumbs
  • 2 tablespoons sugar
  • Pinch fine salt

For Brownie:

  • 8 tablespoons (1 stick) unsalted butter
  • 4 ounces unsweetened chocolate - chopped
  • 1 cup packed light brown sugar
  • 3/4 cup white sugar
  • 1-1/2 teaspoons pure vanilla extract
  • 1/2 teaspoon fine salt
  • 4 large cold eggs
  • 1 cup all-purpose flour

For Topping:

  • 2 cups mini marshmallows
  • 10 mini reese's peanut butter cups - cut in half
  • 1/4 cup peanut butter - melted

Adapted from Food Network


Position a rack in the lower third of the oven and heat oven to 325 degrees F. Line an 8 by-8-inch square baking pan with foil so it hangs over the edges by about 1 inch.

For the crust: Lightly butter the foil with some of the melted butter. Stir the rest of the butter together with the crumbs, sugar, and salt in a medium bowl. Press the crumb mixture evenly over the bottom of the pan. Bake until golden brown, about 20 minutes.

Meanwhile, make the brownie. Put the butter and chocolate in a medium microwave safe bowl. Melt in the microwave on 75 percent power for 2 minutes. Stir, and microwave again until completely melted, about 2 minutes more. Alternatively, put the butter and chocolate in a heatproof bowl. Bring a saucepan filled with 1 inch or so of water to a very slow simmer; set the bowl on the pan without touching the water. Stir occasionally until melted. Stir the light brown and white sugars, vanilla and salt into the melted chocolate. Add the eggs and beat vigorously to make a thick and glossy batter. Add the flour and stir until just incorporated.

Pour batter into the prepared pan. Bake until the top is crispy and a toothpick inserted into the middle comes out mostly clean, with a few crumbs, about 40 to 45 minutes.

Remove from the oven and cover with marshmallows and reese's cups. Put back into oven for approximately 5 minutes. You just want to melt the marshmallows a little. To long in the oven and they will get crunchy. After brownies are cooled pull out of pan and pull foil off the sides. Melt peanut butter until thin in either the microwave or small saucepan over medium heat. Drizzle over brownies. Cut and serve.

    Since we are not counting calories, this would be perfect with a scoop of vanilla ice cream on top.

    I think with all of these awesome toppings a super sweet brownie is nowhere near necessary. Although making and eating a whole pan of this is!

    I will make a deal with you. You wanted some of my Toll House Cookie Pie Bars. I will trade with you. You send me some of these and I will send you those and we will both be happy or we can both make them, ourselves. 🙂
