Ingredients You’ll Need

Before you begin, gather these ingredients. It’s always a good idea to measure everything out beforehand to ensure a smooth baking process.

For the Brownie Layer:

• 1 cup (2 sticks) unsalted butter, melted
• 2 cups granulated sugar
• 1 cup unsweetened cocoa powder
• 1 teaspoon salt
• 1 teaspoon baking powder
• 1 tablespoon vanilla extract
• 4 large eggs
• 1 cup all-purpose flour

For the Marshmallow Layer:

• 1 (10-ounce) package large marshmallows
• 2 tablespoons unsalted butter
• Optional: 1 cup chocolate chips, chopped nuts, or other toppings

Equipment You’ll Need

• 9×13 inch baking pan
• Parchment paper
• Mixing bowls
• Whisk
• Spatula
• Measuring cups and spoons

Step-by-Step Instructions

Now, let’s get to the fun part: baking! Follow these detailed instructions to create your own batch of irresistible Brownie Mallow Bars.

Step 1: Prepare the Pan

Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving an overhang on the sides. This will make it easy to lift the bars out of the pan later. Grease the parchment paper with cooking spray or butter for extra insurance.

Step 2: Make the Brownie Batter

In a large mixing bowl, combine the melted butter, sugar, cocoa powder, salt, and baking powder. Whisk until well combined and smooth. The mixture will be thick.

Add the vanilla extract and eggs, one at a time, whisking well after each addition. Be sure to fully incorporate each egg before adding the next.

Gradually add the flour, mixing until just combined. Be careful not to overmix the batter, as this can result in tough brownies. A few streaks of flour are okay.

Step 3: Bake the Brownie Layer

Pour the brownie batter into the prepared baking pan and spread it evenly. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with moist crumbs attached. The edges should be set, but the center should still be slightly soft. Don’t overbake!

Step 4: Prepare the Marshmallow Layer

While the brownie layer is baking, prepare the marshmallow layer. In a large microwave-safe bowl, combine the marshmallows and butter.

Microwave on high for 1-2 minutes, stirring every 30 seconds, until the marshmallows are melted and smooth. Be careful not to burn the marshmallows.

Alternatively, you can melt the marshmallows and butter in a saucepan over low heat, stirring constantly until melted and smooth.

Step 5: Add the Marshmallow Topping

Once the brownie layer is done baking, remove it from the oven and immediately spread the melted marshmallow mixture evenly over the top. Use a spatula to gently spread the marshmallows.

If desired, sprinkle your favorite toppings, such as chocolate chips, chopped nuts, or sprinkles, over the marshmallow layer.

Step 6: Let Cool and Set

Let the bars cool completely in the pan before cutting. This will allow the marshmallow layer to set properly. This usually takes about 1-2 hours at room temperature, or you can speed up the process by refrigerating them for about 30 minutes.

Step 7: Cut and Serve

Once the bars are completely cool and set, use the parchment paper overhang to lift them out of the pan. Cut the bars into squares and serve. Enjoy!

Tips for Perfect Brownie Mallow Bars

• Don’t Overbake the Brownies: Overbaked brownies will be dry and crumbly. Aim for a moist and fudgy texture.
• Use High-Quality Cocoa Powder: The quality of your cocoa powder will significantly impact the flavor of the brownies. Use a good quality Dutch-processed cocoa powder for the best results.
• Melt the Marshmallows Carefully: Be careful not to burn the marshmallows when melting them. Stir frequently and microwave in short intervals.
• Let the Bars Cool Completely: Cooling the bars completely is essential for the marshmallow layer to set properly. If you cut them too soon, the marshmallows will be sticky and messy.
• Line the Pan with Parchment Paper: This makes it easy to lift the bars out of the pan and prevents them from sticking.
• Use a Warm Knife to Cut: For clean cuts, use a warm knife. Run the knife under hot water and dry it before each cut.

Variations and Customizations

The possibilities are endless when it comes to customizing these Brownie Mallow Bars. Here are a few ideas to get you started:

• Chocolate Chip Brownie Mallow Bars: Add 1 cup of chocolate chips to the brownie batter.
• Nutty Brownie Mallow Bars: Add 1 cup of chopped nuts (walnuts, pecans, or almonds) to the brownie batter or sprinkle them over the marshmallow topping.
• Pretzel Brownie Mallow Bars: Add 1 cup of crushed pretzels to the brownie batter or sprinkle them over the marshmallow topping for a salty-sweet treat.
• Peanut Butter Brownie Mallow Bars: Swirl peanut butter into the brownie batter or drizzle melted peanut butter over the marshmallow topping.
• S’mores Brownie Mallow Bars: Add crushed graham crackers to the brownie batter and sprinkle mini marshmallows and chocolate chips over the marshmallow topping.
• Mint Chocolate Brownie Mallow Bars: Add a few drops of peppermint extract to the brownie batter and sprinkle crushed candy canes over the marshmallow topping.
• Caramel Brownie Mallow Bars: Drizzle caramel sauce over the marshmallow topping.

Storage Instructions

Store the Brownie Mallow Bars in an airtight container at room temperature for up to 3 days. You can also store them in the refrigerator for up to 5 days. The bars may become slightly firmer in the refrigerator.
