• 1/4 cup vegetable oil
• 1/4 cup water

Middle Layer (Marshmallow Layer):

Preparation:

Step 1: Preheat the Oven and Prepare the Pan
Preheat your oven according to the brownie mix instructions, usually around 350°F (175°C). Spray a 9×13-inch baking pan with non-stick cooking spray to ensure easy removal of the bars after baking.

Step 2: Prepare and Bake the Brownie Layer
In a large mixing bowl, prepare the brownie batter according to the instructions on the box. This typically involves mixing the brownie mix with 2 large eggs, 1/4 cup of vegetable oil, and 1/4 cup of water. Stir until well combined, ensuring there are no lumps. Pour the brownie batter into the prepared baking pan and spread it out evenly. Bake the brownies according to the time suggested on the box, typically 25-30 minutes, or until a toothpick inserted into the center comes out clean. Allow the brownies to cool completely before moving to the next step.

Step 3: Spread the Marshmallow Crème
Once the brownies are completely cooled, take the jar of marshmallow crème and spread it evenly over the entire surface of the brownies. This layer adds a soft, gooey sweetness that pairs perfectly with the rich chocolate flavor of the brownie base. Use a spatula to smooth it out for an even layer.

Step 4: Prepare the Chocolate Peanut Butter Crunch Layer
In a microwave-safe bowl, combine the 2 cups of semi-sweet chocolate chips and 1 cup of peanut butter. Microwave the mixture in 30-second intervals, stirring in between each interval, until the chocolate and peanut butter are fully melted and combined. Be careful not to overheat, as the chocolate can burn easily. Once melted and smooth, stir in the 3 cups of Rice Krispies cereal. This mixture creates the crispy, chocolate-peanut butter topping that adds both flavor and texture to the bars.

Step 5: Assemble the Layers
Carefully pour the chocolate-peanut butter-Rice Krispies mixture over the marshmallow layer, using a spatula to spread it out evenly. Press gently to make sure the top layer adheres to the marshmallow crème without squishing it too much. This crunchy layer adds a satisfying texture and completes the indulgent experience of the bars.

Step 6: Chill and Set
Cover the baking pan with plastic wrap or aluminum foil and place it in the refrigerator for at least 2 hours to allow the layers to set. This chilling time helps the top layer firm up and makes the bars easier to cut into neat squares.

Step 7: Cut and Serve
Once chilled, remove the pan from the refrigerator and use a sharp knife to cut the bars into squares. You can make anywhere from 24-36 bars depending on how large you want each portion to be. Serve the bars chilled for a firm texture or at room temperature for a softer bite.

COOKING NOTE: To make cutting the bars easier, lightly grease the knife with non-stick spray or butter. This will help prevent the marshmallow and chocolate layers from sticking to the blade, allowing for cleaner cuts.

Serving Suggestions:

These Brownie Bomb Bars are perfect for serving at parties, potlucks, or as an after-dinner dessert. Pair them with a scoop of vanilla ice cream or a cold glass of milk for the ultimate treat. You can also add a drizzle of caramel or chocolate syrup over the bars for an extra touch of indulgence.

Tips:

1. Brownie Base: For an extra-rich brownie layer, use a “fudge” style brownie mix or add an extra egg for a more cake-like texture.
2. Customize the Topping: Feel free to experiment with the top layer by adding extras like chopped peanuts, sprinkles, or M&M’s to the chocolate-peanut butter mixture before spreading it on top.
3. Make Ahead: These bars can be made a day ahead and stored in the refrigerator. They also freeze well—simply wrap the bars individually in plastic wrap and store them in an airtight container in the freezer for up to a month.
4. Serving Temperature: These bars are delicious served chilled for a firmer, crunchier texture, but they also taste amazing at room temperature where the marshmallow layer becomes softer and gooier.
