Ingredients
  

For the Brownie Base
  • 18 ounces brownie mix plus ingredients called for on the box (eggs, oil, water)
For the Marshmallow Layer
  • 7 ounces marshmallow creme
For the Topping
  • 25 Reese's miniatures Reese's miniatures halved
  • 12 ounces semi-sweet chocolate chips
  • 1 cup creamy peanut butter not natural
  • 3 cups crispy rice cereal

Equipment

  • 9x13-inch Baking Dish
  • Microwave-safe bowl
  • Offset spatula
  • Sharp knife

Method
 

  1. Step 1: Prepare the Brownie Base. Get your brownie batter ready according to the package directions for a 9x13 baking dish. Bake them until they're perfectly set. Once they're out of the oven, let them cool completely. For the best results and easier handling, chill the cooled brownies in the refrigerator for at least an hour.
  2. Step 2: Add the Marshmallow Layer. Once your brownies are nice and chilled, spread the marshmallow creme evenly all over the top. Pop the pan back into the refrigerator for at least 30 minutes to let the marshmallow creme set up a bit.
  3. Step 3: Get Ready for the Reese's. Arrange your halved Reese's miniatures on top of the chilled marshmallow creme, ensuring an even distribution.
  4. Step 4: Create the Peanut Butter Chocolate Crunch. In a microwave-safe bowl, combine the semi-sweet chocolate chips and the creamy peanut butter. Microwave in 30-second intervals, stirring well between each interval, until smooth and melty.
  5. Step 5: Coat the Cereal. Gently stir the crispy rice cereal into the melted chocolate and peanut butter mixture, ensuring every piece is coated.
  6. Step 6: Top it Off. Carefully spread this crunchy cereal mixture over the top of the Reese's miniatures, covering them completely. Press gently to help it adhere.
  7. Step 7: Chill and Cut. Return the pan to the refrigerator for another hour to allow all layers to firm up. Once chilled, use a sharp knife to cut them into desired bar size.

Notes

Don't Overbake the Brownies: A slightly underbaked brownie is better than an overbaked one, especially when you're adding more layers. They'll continue to cook slightly as they cool. Chill, Chill, Chill: Seriously, don't skip the chilling steps! They are key to getting clean layers and easy slicing. Smooth Melting: When melting the chocolate and peanut butter, use short intervals and stir frequently to prevent scorching. Even Spreading: For the marshmallow creme and the cereal mixture, an offset spatula can be your best friend for achieving smooth, even layers. Cooling Time: Be patient! Letting them fully set in the fridge is essential for that perfect bar texture.
