Ingredients for Mounds Brownies
You only need a few everyday ingredients to make these chocolate coconut brownies.
For the Brownie Base
- 1 box family-size brownie mix for a 9-by-13-inch pan: Choose a fudgy brownie mix for a rich, dense base.
- Ingredients listed on the brownie mix package: Usually eggs, vegetable oil, and water. The amounts vary depending on the brand, so follow the package directions.
For the Coconut Layer
- 5 cups sweetened shredded coconut: Creates the thick, chewy coconut center that makes these brownies special.
- 1 can (14 ounces) sweetened condensed milk: Binds the coconut together and adds creamy sweetness.
- 1 cup powdered sugar: Adds sweetness and helps create a cohesive filling.
For the Chocolate Topping
- 1 container (16 ounces) prepared chocolate frosting: Provides a smooth chocolate finish without requiring a separate ganache recipe.
- 1 to 2 tablespoons milk or heavy cream, optional: Helps thin the frosting if needed to make it easier to spread or pour.
Optional Additions
- 1 teaspoon vanilla extract: Adds warmth to the coconut filling.
- 1/2 teaspoon almond extract: Provides a subtle almond flavor that complements chocolate and coconut.
- 1/2 cup mini chocolate chips: Adds extra chocolate to the coconut layer.
- Toasted shredded coconut: Makes a simple garnish and adds a lightly nutty flavor.
- Flaked sea salt: Balances the sweetness with a delicate salty finish.
How to Make Mounds Brownies
Step 1: Prepare the Baking Pan
Preheat your oven to the temperature recommended on the brownie mix package, usually 325°F to 350°F (165°C to 180°C).
Grease a 9-by-13-inch baking pan or line it with parchment paper, leaving some overhang on two opposite sides. The parchment makes it easier to lift the finished brownies out of the pan for neat slicing.
Step 2: Prepare the Brownie Batter
Prepare the brownie mix according to the package instructions, combining the mix with the required eggs, oil, and water.
Stir until the ingredients are combined and the batter is smooth. Avoid overmixing, which can affect the texture of the finished brownies.
Pour the batter into the prepared pan and spread it evenly into the corners.
Step 3: Bake the Brownies
Bake according to the package directions, usually about 28 to 35 minutes, depending on the brand and your oven.
Check the brownies near the end of the recommended baking time by inserting a toothpick into the center. For a fudgy texture, a few moist crumbs should cling to the toothpick, but there should be no wet batter.
Avoid overbaking because a dry brownie base can make the finished bars less tender.
Step 4: Make the Coconut Filling
While the brownies bake, combine the sweetened shredded coconut, sweetened condensed milk, and powdered sugar in a large bowl.
Stir thoroughly until the coconut is evenly coated and the mixture becomes thick, sticky, and moist.
If desired, add the vanilla extract or almond extract. For an extra chocolatey version, fold in the mini chocolate chips.
Set the mixture aside so it is ready when the brownies come out of the oven.
Step 5: Add the Coconut Layer
As soon as the brownies finish baking, carefully remove the pan from the oven and place it on a heat-resistant surface.
While the brownie base is still hot, spoon the coconut mixture over the top. Spread it gently into an even layer, covering the entire surface from edge to edge.
Use the back of a spoon or a spatula to distribute the filling without pressing too hard into the brownies.
Applying the coconut filling while the brownie surface is still hot helps the layers adhere as the dessert cools.
Step 6: Prepare the Chocolate Topping
Transfer the prepared chocolate frosting to a microwave-safe bowl.
Heat it in the microwave for 15 to 20 seconds at a time, stirring between intervals, until it becomes smooth and pourable. This usually takes about 30 to 45 seconds in total, depending on the microwave.
Do not overheat the frosting. If it is still too thick, stir in a little milk or heavy cream, adding just one tablespoon at a time.
The frosting should flow easily without becoming watery.
Step 7: Add the Chocolate Layer
Pour the warm frosting over the coconut filling.
Use an offset spatula or the back of a spoon to spread it evenly across the surface, making sure to cover the edges.
A complete chocolate coating helps keep the coconut layer moist and gives the brownies a smooth, finished appearance.
If desired, sprinkle toasted coconut or a small amount of flaked sea salt over the top before the frosting sets.
Step 8: Cool and Chill
Allow the brownies to cool completely at room temperature.
Once cooled, refrigerate the pan for at least 1 hour, or until the chocolate topping is firm and the layers have set.
For the cleanest slices, chill the brownies for 1 to 2 hours before cutting.
Step 9: Slice and Serve
Use the parchment overhang to lift the brownies from the pan, if you lined it.
Cut into approximately 24 bars with a sharp knife. For neater edges, warm the knife under hot water, dry it thoroughly, and wipe it clean between cuts.
Serve the brownies chilled or let them sit at room temperature for about 20 to 30 minutes for a softer, fudgier texture.
Tips for the Best Mounds Brownies
Use sweetened shredded coconut. It provides the familiar sweetness and chewy texture associated with chocolate-coconut candy bars. Unsweetened coconut can be used, but the filling will taste less sweet.
Spread the coconut layer over warm brownies. Adding the filling while the brownie base is still hot helps the layers stick together as they cool.
Do not overbake the brownie base. Follow the package directions and begin checking for doneness near the minimum baking time. Slightly fudgy brownies provide the best contrast to the chewy coconut layer.
Mix the coconut filling thoroughly. Make sure the condensed milk coats the shredded coconut evenly. Dry pockets can make the filling crumbly.
Adjust the frosting consistency carefully. Warm the frosting just enough to make it pourable. Add milk or cream sparingly if it needs thinning.
Chill before slicing. The chocolate topping and coconut filling become firmer as they cool, making the brownies easier to cut into neat squares.
Clean the knife between cuts. Wiping the blade after each slice prevents chocolate and coconut from collecting on the knife and creating messy edges.
Easy Variations
Dark Chocolate Mounds Brownies
Use a dark chocolate brownie mix and dark chocolate frosting for a deeper, less sweet chocolate flavor. This variation balances the sweetness of the coconut filling.
Almond Joy-Inspired Brownies
Add 1 cup of chopped almonds to the coconut mixture and sprinkle a few additional almonds over the chocolate topping. The combination of chocolate, coconut, and almonds creates a delicious variation.
Extra Chocolate Coconut Brownies
Stir mini chocolate chips into the coconut filling and finish the brownies with a drizzle of melted chocolate once the frosting has set.
Toasted Coconut Brownies
Toast about 1 cup of shredded coconut in a dry skillet over low to medium-low heat, stirring frequently until lightly golden. Allow it to cool, then sprinkle it over the chocolate topping or mix some into the filling.
Homemade Brownie Base
If you prefer to bake from scratch, replace the boxed brownie mix with your favorite recipe designed for a 9-by-13-inch pan. Bake until the center is set but still moist, then continue with the coconut and chocolate layers.
Sea Salt Chocolate Coconut Brownies
Sprinkle a small amount of flaky sea salt over the chocolate topping before it sets. The subtle saltiness contrasts with the sweet coconut filling and rich chocolate.
Holiday Coconut Brownies
Add a decorative drizzle of white chocolate over the chilled brownies. This creates an attractive finish for holiday dessert trays and special occasions.
What to Serve with Mounds Brownies
These rich dessert bars are delicious on their own, but they also pair well with a variety of simple accompaniments.
- Cold milk: A classic pairing that balances the richness of the chocolate.
- Hot coffee: The slight bitterness of coffee complements the sweet coconut filling.
- Vanilla ice cream: Adds a cool, creamy contrast to the dense brownies.
- Fresh strawberries: Their light, fruity flavor balances the richness of the dessert.
- Whipped cream: A small dollop adds a soft, airy finish.
- Hot chocolate: Makes a cozy pairing for winter evenings and holiday gatherings.
For a simple dessert platter, arrange the brownies alongside fresh berries and small portions of vanilla ice cream.
How to Store Mounds Brownies
Because these brownies contain a moist coconut filling and a chocolate topping, proper storage helps maintain their flavor and texture.
At room temperature: Store the brownies in an airtight container in a cool place for up to 2 to 3 days, provided the kitchen is not excessively warm.
In the refrigerator: Place the brownies in an airtight container and refrigerate for up to 1 week. Separate layers with parchment paper if stacking them.
In the freezer: Wrap individual bars tightly and place them in a freezer-safe container or bag. Freeze for up to 3 months for the best quality.
To serve refrigerated brownies, let them stand at room temperature for about 20 to 30 minutes. This softens the brownie base while keeping the layers intact.
Can You Make Mounds Brownies Ahead of Time?
Yes. These brownies are an excellent make-ahead dessert because they need time to cool and chill before slicing.
You can prepare them a day before serving and keep them covered in the refrigerator. The chilling time allows the coconut filling and chocolate topping to firm up, making the bars easier to cut and transport.
For parties, bake and assemble the brownies the day before, then slice them shortly before serving.
Frequently Asked Questions
Do Mounds Brownies taste like the candy bar?
They are inspired by the classic chocolate-and-coconut combination. The fudgy brownie base, sweet coconut filling, and chocolate topping recreate similar flavors in a soft, chewy dessert bar.
Can I use homemade brownies instead of a boxed mix?
Yes. Use your favorite brownie recipe that fits a 9-by-13-inch pan. Follow its baking instructions, then add the coconut layer while the brownies are still hot.
Can I use unsweetened shredded coconut?
Yes, but the filling will be less sweet. You can add a little extra powdered sugar to taste, keeping in mind that the sweetened condensed milk already provides substantial sweetness.
Why is my coconut layer falling off?
This can happen if the coconut mixture is too dry or if it is spread over a completely cooled brownie base. Make sure the coconut is thoroughly coated with condensed milk and apply the filling while the brownies are still hot.
Why is my chocolate topping too thick?
Some prepared frostings are naturally thick. Warm the frosting in short microwave intervals, stirring between each one. If necessary, add a small amount of milk or heavy cream until it becomes easy to spread.
How do I get clean brownie slices?
Chill the brownies until the topping is firm. Use a sharp knife, warm it under hot water if needed, dry it completely, and wipe the blade between cuts.
Do Mounds Brownies need to be refrigerated?
Refrigeration is recommended for longer storage and helps the layers stay firm. They can be kept at room temperature for a short period in a cool environment, but avoid leaving them out for extended periods in warm conditions.
Can I freeze Mounds Brownies?
Yes. Wrap the cooled and sliced brownies individually, then store them in a freezer-safe container for up to 3 months. Thaw them in the refrigerator overnight or at room temperature until ready to serve.
