This recipe from Diane Morrisey uses a cake mix “hack.” I almost never use cake mixes but here is a great reason to make an exception…
2 packages of Duncan Hines Chewy Fudge premium brownie mix
1 ½ cups chunky peanut butter
2 cups semisweet chocolate chips
1 cup creamy peanut butter
3 cups Rice Krispies
Preheat oven to 350F and line a 9×13-inch baking pan with parchment paper sprayed with cooking spray. Prepare the brownie mix according to directions on the box (add ½ cup water, ½ cup grapeseed oil and 2 eggs) and bake for 32 minutes.
Remove from oven and immediately spread 1 ½ cups chunky peanut butter over the warm brownie.
In a double boiler, melt together the chocolate chips and creamy peanut butter until smooth. Remove from the heat and stir in the Rice Krispies.
Spread over the chunky peanut butter layer and refrigerate until ready to serve.
