Why You’ll Love These Mounds Brownies

There are plenty of brownie recipes out there, but this one stands out for several reasons.

First, it’s incredibly simple. Starting with a boxed brownie mix eliminates guesswork and ensures consistent results every time. You don’t need to worry about ratios, overmixing, or complicated techniques. This makes the recipe accessible to bakers of all skill levels.

Second, the coconut layer is rich, sweet, and perfectly textured. Made with shredded coconut, sweetened condensed milk, and powdered sugar, it’s moist and chewy without being overly sticky. When spread over hot brownies, it gently melts into the surface, creating a seamless layer that adheres beautifully.

Finally, the chocolate frosting ties everything together. By gently warming the frosting until it’s pourable, you create a smooth, even top layer that seals in the coconut and gives the brownies a polished, professional finish. The result is a dessert that looks as good as it tastes.

Ingredients Overview

This recipe uses straightforward, easy-to-find ingredients. Each one plays an important role in achieving the final texture and flavor.

Brownie Layer

1 box brownie mix (designed for a 9×13-inch pan)
Ingredients listed on the box (typically eggs, oil, and water)

The brownie layer forms the foundation of the dessert. A fudgy brownie mix works especially well, but any standard 9×13-size mix will do.

Coconut Layer

5 cups shredded coconut
1 can sweetened condensed milk
1 cup powdered sugar

This mixture mimics the coconut filling found in a Mounds candy bar. The sweetened condensed milk binds the coconut together while adding richness, and the powdered sugar enhances sweetness and smoothness.

Chocolate Topping

1 container chocolate frosting

Using store-bought frosting keeps the recipe simple and consistent. Once warmed, it becomes easy to pour and spread evenly over the coconut layer.

Equipment Needed

You don’t need any special tools to make these brownies, which is another reason this recipe is so approachable.

9×13-inch baking pan
Mixing bowls
Spoon or spatula
Microwave-safe bowl
Offset spatula or knife for spreading
Measuring cups

Lining your pan with parchment paper is optional but helpful if you want easy removal and cleaner slices.

Step-by-Step Instructions

Step 1: Prepare the Brownie Base

Begin by preheating your oven according to the instructions on your brownie mix box. Grease a 9×13-inch baking pan or line it with parchment paper.

Prepare the brownie batter exactly as directed on the box. Mix until just combined, being careful not to overmix, which can make brownies tough. Pour the batter evenly into the prepared pan, smoothing the top with a spatula.

Bake according to the package directions. The brownies should be set but still moist in the center. Avoid overbaking, as the brownies will continue to firm up slightly once removed from the oven.

Step 2: Make the Coconut Filling

While the brownies are baking, prepare the coconut layer.

In a large mixing bowl, combine the shredded coconut and sweetened condensed milk. Stir until the coconut is fully coated and evenly moistened. Add the powdered sugar and mix thoroughly. The mixture should be thick, sticky, and cohesive, but still easy to spread.

If the mixture feels too dry, you can add a tablespoon or two of additional condensed milk. If it feels too wet, a small amount of powdered sugar can help thicken it.

Set the mixture aside until the brownies are finished baking.

Step 3: Add the Coconut Layer to Hot Brownies

As soon as the brownies come out of the oven, work quickly while they’re still hot.

Spoon the coconut mixture over the surface of the brownies. Using a spatula or the back of a spoon, gently spread the mixture into an even layer. Be careful not to press too hard, as the brownies underneath will be soft.

The heat from the brownies helps the coconut layer adhere and slightly melt into the surface, creating a unified texture once cooled.

Step 4: Prepare the Chocolate Frosting

Place the container of chocolate frosting in the microwave. Heat it in short intervals, about 10–15 seconds at a time, stirring between each interval. You want the frosting to be pourable, not hot or runny.

Once the frosting reaches a smooth, fluid consistency, carefully pour it over the coconut layer.

Step 5: Spread and Seal the Brownies

Using an offset spatula or knife, gently spread the frosting over the entire surface, making sure to reach the edges. Sealing the edges helps lock in moisture and keeps the coconut layer from drying out.

Take your time to create an even, smooth top. This final layer gives the brownies their classic, finished look.

Cooling and Cutting

Allow the brownies to cool completely at room temperature before cutting. This step is essential for clean slices and properly set layers.

Once cooled, use a sharp knife to cut into squares. For the cleanest cuts, wipe the knife with a damp cloth between slices.

These brownies can be cut into large squares for a decadent dessert or smaller pieces for parties and gatherings.

Texture and Flavor Profile

These Mounds Brownies are rich and indulgent, with multiple layers of flavor and texture.

The brownie base is dense, fudgy, and chocolatey.
The coconut layer is chewy, sweet, and moist, offering a pleasant contrast to the brownie.

Storage and Make-Ahead Tips

These brownies store very well, making them ideal for baking ahead of time.

Room Temperature: Store in an airtight container for up to 3 days.
Refrigerator: Store for up to 1 week. Chilling helps the layers stay firm and makes slicing easier.
Freezer: These brownies freeze well. Wrap individual pieces tightly and freeze for up to 3 months. Thaw at room temperature before serving.

Variations and Customizations

This recipe is versatile and can be adapted to suit your preferences.

Dark Chocolate Lovers: Use dark chocolate frosting or a dark chocolate brownie mix.
Extra Coconut Flavor: Add a few drops of coconut extract to the coconut mixture.
Nut Addition: Sprinkle chopped almonds over the coconut layer before adding the frosting for a nod to Almond Joy.
Homemade Frosting: Replace store-bought frosting with homemade chocolate ganache if desired.

Tips for Success

Spread the coconut layer while the brownies are hot to ensure proper adhesion.
Don’t overheat the frosting; gentle warming is key.
Allow sufficient cooling time before cutting to maintain clean layers.
Use sweetened shredded coconut for best flavor and texture.
