Preheat the oven according to the brownie mix package and prepare the 18‑oz brownie mix following the package directions for cake‑like brownies; pour the batter into the prepared pan and bake as directed.
  • Cool the brownies completely in the pan on a wire rack.
  • Spread the entire 7‑oz jar of marshmallow creme evenly over the cooled brownies, reaching to the edges.
  • In a medium saucepan set over low heat, combine 1 cup creamy peanut butter and the 12‑oz package semi‑sweet chocolate chips. Stir continuously over low heat until the mixture is fully melted and smooth. Remove the pan from the heat.

  • Immediately spread the coated Rice Krispie mixture evenly over the marshmallow layer, pressing lightly so it adheres.

You will need to double our homemade recipe and bake in a 9×13-inch pan.
I leave out the walnuts or pecans when I use this homemade brownie recipe in this dessert.
I use Jif smooth peanut butter. You can use any brand of peanut butter that you enjoy. Smooth or crunchy works just fine. ​
I used semi-sweet chocolate chips. Milk chocolate or dark chocolate chips would also work great.
I melted the peanut butter and chocolate on the stovetop, but you can also melt them in the microwave.
How do I know if my brownies are done? Bake the brownies until a toothpick inserted into the center of the brownies comes out clean or with only crumbs, no batter on it.
My biggest tip for making these brownies is to line your pan with parchment paper or aluminum foil before baking the brownies.You want the parchment paper to hang over the edges a bit. This will help you when you go to get the brownies out of the pan. I run a knife around the sides of the pan before lifting them out of the pan.

You can cut the recipe in half and make the recipe in an 8-inch or 9-inch square pan.
How to store brownies? Store the brownies in an airtight container on the countertop.
How long do brownies keep? The brownies will keep for 3 to 4 days in an air-tight container.
