Step-by-Step Instructions

Step 1 — Prepare the Brownie Base

Preheat your oven to 350°F (175°C) and line a 9×9-inch baking pan with parchment paper, leaving an overhang for easy removal. Prepare your favorite boxed brownie mix according to package directions, or use your preferred homemade recipe. Spread the batter evenly into the prepared pan.

Step 2 — Bake the Brownie Layer

Bake the brownies for 20-25 minutes, or until the top is set and a toothpick inserted into the center comes out with a few moist crumbs attached. Do not overbake, as the brownies will continue to set as they cool and will be baked again with the marshmallow layer.

Step 3 — Add the Marshmallow Layer

Remove the pan from the oven and immediately sprinkle a 10-ounce bag of mini marshmallows evenly over the hot brownies. Return the pan to the oven for 3-5 minutes, just until the marshmallows are puffy and begin to melt. Watch closely to prevent burning.

Step 4 — Create the Peanut Butter-Chocolate Topping

While the marshmallows are warming, combine 1 cup of semi-sweet chocolate chips, 1 cup of creamy peanut butter, and 1 tablespoon of butter in a microwave-safe bowl. Heat in 30-second intervals, stirring between each, until the mixture is smooth and fully melted.

Step 5 — Spread the Topping

Carefully pour the warm peanut butter-chocolate mixture over the marshmallow layer. Use an offset spatula or the back of a spoon to gently spread it into an even layer, covering the marshmallows completely. Work gently to avoid mixing the layers.

Step 6 — Add the Final Crispy Element

Immediately after spreading the topping, generously sprinkle 1 to 1 ½ cups of chopped Reese’s Peanut Butter Cups over the surface. Press them down lightly so they adhere to the warm, soft topping. This creates the signature crispy, crunchy texture as it sets.

Step 7 — Cool Completely to Set

Allow the pan to cool completely on a wire rack at room temperature. For the best texture and cleanest cuts, chill the pan in the refrigerator for at least 2 hours, or until the topping is firm and set. The layers will hold their distinct shape when sliced.

Step 8 — Slice and Serve

Use the parchment paper overhang to lift the entire block of Decadent Reese’s Marshmallow Brownies out of the pan. Place it on a cutting board and use a sharp knife to slice into squares. For clean cuts, wipe the knife blade clean between slices.

Healthier Alternatives

• Protein powder brownies — Replace half the flour with chocolate protein powder for a boost while keeping the rich flavor.
• Almond flour base — Use almond flour instead of all-purpose for a gluten-free, lower-carb option with a nutty taste.
• Natural peanut butter — Opt for unsweetened natural peanut butter to reduce added sugars and sodium in the peanut butter layer.
• Greek yogurt frosting — Substitute marshmallow cream with Greek yogurt mixed with peanut butter for a protein-rich, lower-sugar topping.
• Dark chocolate chips — Choose sugar-free or high-percentage dark chocolate chips to cut down on sugar while enhancing the chocolate intensity.
• Applesauce for oil — Replace oil with unsweetened applesauce in the brownie batter to reduce fat while maintaining moisture.
• Coconut milk marshmallow — Use dairy-free marshmallow fluff made with coconut milk for a creamy, vegan-friendly alternative.
• Stevia sweetener — Swap granulated sugar with stevia in the brownie mix to lower the carbohydrate content without sacrificing sweetness.

Serving Suggestions

• Pair with a cold glass of milk or a scoop of vanilla ice cream to complement the rich chocolate and peanut butter flavors.
• Serve warm at parties or potlucks to highlight the gooey marshmallow layer.
• Enjoy as an indulgent dessert after a casual family dinner or during holiday gatherings.
• Cut into small squares for a bite-sized treat at bake sales or coffee breaks.
• Garnish with a sprinkle of sea salt or crushed Reese’s Pieces for extra texture and visual appeal.
• Plate alongside fresh berries to balance the sweetness with a touch of acidity.

Common Mistakes to Avoid

• Mistake: Overmixing the brownie batter after adding flour. Fix: Mix just until the flour disappears to maintain a fudgy texture.
• Mistake: Spreading marshmallow layer while brownies are too hot. Fix: Let brownies cool for 10-15 minutes to prevent the marshmallow from melting into the base.
• Mistake: Using cold ingredients for the peanut butter topping. Fix: Ensure butter and peanut butter are at room temperature for a smooth, spreadable consistency.
• Mistake: Baking in a glass pan at the metal pan temperature. Fix: Reduce oven temperature by 25°F if using glass to prevent over-baked edges.
• Mistake: Adding Reese’s pieces too early in baking. Fix: Press candies into the topping after baking to maintain their shape and prevent burning.
• Mistake: Cutting brownies before they are fully set. Fix: Allow the chocolate-peanut butter layers to cool completely for clean slices.
• Mistake: Skipping the parchment paper lining. Fix: Line your pan with parchment for easy removal of all four intact layers.
• Mistake: Not properly measuring flour. Fix: Spoon flour into measuring cup and level for accuracy; too much creates cakey brownies.
• Mistake: Rushing the layering process. Fix: Allow each layer to set slightly before adding the next to maintain distinct textures.
• Mistake: Using expired baking powder. Fix: Test your leavener before starting to ensure proper rise in the brownie base.

Storing Tips

• Fridge: Store in an airtight container for up to 5 days; the marshmallow layer stays freshest when chilled.
• Freezer: Wrap tightly or place in a freezer-safe container for up to 3 months; thaw in the refrigerator before serving.
• Reheat: Warm individual portions in the microwave for 10–15 seconds until the chocolate softens, ensuring an internal temperature of at least 165°F for food safety.

Proper storage keeps the layers of these Decadent Reese’s Marshmallow Brownies distinct and the peanut butter-chocolate topping delightfully crispy.
