How to Make Easy 3-Layer Mounds Brownies
Step 1: Prepare the Pan
Preheat the oven to 350°F (175°C).
Line a 9×13-inch baking pan with parchment paper, leaving some overhang on the sides.
Lightly grease the parchment.
Step 2: Make the Brownie Batter
In a large bowl, whisk together the melted butter and sugar.
Add the eggs one at a time, mixing well after each addition.
Stir in the vanilla.
Step 3: Add the Dry Ingredients
Add:
- Flour
- Cocoa powder
- Salt
- Baking powder
Fold gently until just combined.
Avoid overmixing.
Step 4: Bake the Brownie Layer
Spread the brownie batter evenly into the prepared pan.
Bake for approximately 25–30 minutes.
The center should be set, but a toothpick may still come out with a few moist crumbs.
Do not overbake, or the brownies can become dry.
Step 5: Cool
Remove the pan from the oven.
Let the brownie layer cool completely before adding the coconut filling.
This helps keep the layers neat and distinct.
Make the Coconut Layer
Step 6: Mix the Coconut Filling
In a medium bowl, combine:
- Sweetened shredded coconut
- Sweetened condensed milk
- Vanilla
- Pinch of salt
Stir until the coconut is evenly coated.
Step 7: Spread Over the Brownies
Spoon the coconut mixture over the cooled brownie layer.
Spread it gently and evenly all the way to the edges.
Press lightly with the back of a spoon so the coconut layer holds together.
Make the Chocolate Topping
Step 8: Heat the Cream
Place the heavy cream in a small saucepan.
Heat until steaming, but do not boil.
Step 9: Make the Ganache
Place the chocolate chips in a heatproof bowl.
Pour the hot cream over the chocolate.
Let it sit for approximately 2 minutes.
Add the butter.
Stir slowly until smooth and glossy.
Step 10: Spread Over the Coconut Layer
Pour the chocolate ganache over the coconut layer.
Spread evenly with a spatula.
Step 11: Chill
Refrigerate the brownies for approximately 1 hour, or until the chocolate layer is firm.
Step 12: Slice
Use the parchment paper to lift the brownies from the pan.
Cut into squares with a sharp knife.
For the cleanest slices, wipe the knife between cuts.
The Secret to Fudgy Brownies
The most important rule is do not overbake the brownie layer.
The brownies should look set around the edges but still slightly soft in the center.
A toothpick should come out with moist crumbs rather than completely clean.
They will continue to set as they cool.
How to Get Clean Layers
For neat three-layer brownies:
- Cool the brownie layer completely.
- Press the coconut filling evenly.
- Chill the chocolate topping until firm.
- Use a warm, sharp knife.
These small steps make a big difference in presentation.
Easy Boxed Brownie Mix Version
If you want an even faster version, use one box of brownie mix.
Prepare it according to package directions and bake it in a 9×13-inch pan.
Cool completely.
Then add the coconut layer and chocolate topping exactly as written.
This shortcut works very well for busy holidays or last-minute desserts.
Extra-Fudgy Mounds Brownies
For an even richer brownie base, stir 1 cup semisweet chocolate chips into the brownie batter.
You can also add a tablespoon of espresso powder to deepen the chocolate flavor without making the brownies taste strongly of coffee.
Dark Chocolate Mounds Brownies 🍫
Use dark cocoa powder in the brownie base and dark chocolate chips for the topping.
This makes the dessert less sweet and gives it a deeper chocolate flavor.
Almond Coconut Brownies
Add approximately ½ cup chopped toasted almonds to the coconut layer.
You can also place one toasted almond on top of each brownie square.
Chocolate, coconut, and almond make a classic combination.
Chocolate Coconut Brownies with Marshmallow
For a softer, sweeter center, fold approximately 1 cup mini marshmallows into the coconut filling.
Chill thoroughly before cutting.
Coconut Cream Brownies
For an extra-creamy middle, beat 4 ounces softened cream cheese into the sweetened condensed milk before mixing in the coconut.
This gives the center a cheesecake-like richness.
What Chocolate Works Best?
Semisweet chocolate is a good choice because it balances the sweet coconut filling.
You can also use:
- Milk chocolate for sweeter brownies
- Dark chocolate for stronger cocoa flavor
- Bittersweet chocolate for a less-sweet finish
Can I Use Unsweetened Coconut?
Yes, but the filling will be noticeably less sweet and slightly drier.
If using unsweetened coconut, you may want to add a little extra sweetened condensed milk.
Make-Ahead Instructions
These brownies are excellent for making ahead.
Prepare them completely and chill overnight.
Once firm, cut into squares and store in an airtight container.
They’re especially convenient for parties because they actually slice better after chilling.
Storage
Store the brownies in an airtight container in the refrigerator for up to approximately 5 days.
For the best texture, let them sit at room temperature for about 10–15 minutes before serving.
Can You Freeze Mounds Brownies?
Yes.
Cut the brownies into individual squares.
Wrap them well and place them in a freezer-safe container.
Freeze for up to approximately 2–3 months.
Thaw overnight in the refrigerator.
