Ingredients

  • 1 (19.8 ounce) package brownie mix
  • ½ cup vegetable oil
  • ¼ cup water
  • 2 large eggs
  • 1 (10.5 ounce) package miniature marshmallows
  • 2 cups semisweet chocolate chips
  • 1 cup peanut butter
  • 1 tablespoon unsalted butter
  • 1 ½ cups crispy rice cereal

Directions

  • Preheat the oven to 350 degrees F (175 degrees C). Grease a 9x13-inch baking dish.
  • Mix brownie mix, oil, water, and eggs in a large bowl until smooth. Spread evenly in the prepared baking dish.
  • Bake in the preheated oven until a toothpick inserted into the center comes out clean, 28 to 30 minutes. Sprinkle marshmallows over brownie and continue baking until slightly melted, about 3 minutes. Remove from oven and set aside to cool completely.
