Ingredients
Cake
- 2 boxes coconut cake mix
- Ingredients called for on the cake mix boxes (eggs, oil, and water)
Homemade Coconut Frosting

- ½ cup heavy cream
- 2 teaspoons vanilla extract
- 1 teaspoon coconut extract
- Pinch of salt
Topping
- 3 to 4 cups sweetened shredded coconut
How to Make Double Decker Coconut Cake
Step 1
Preheat your oven according to the cake mix directions.
Grease two 9×13-inch baking pans.
Prepare each cake mix according to the package directions.
Divide the batter evenly between the two prepared pans.
Bake according to the package directions until a toothpick inserted into the center comes out clean.
Allow both cakes to cool completely.
Step 2
Prepare the coconut frosting.
In a large mixing bowl, beat the butter until smooth and creamy.
Gradually add the powdered sugar, alternating with the heavy cream until the frosting is light and fluffy.
Mix in the vanilla extract, coconut extract, and a pinch of salt.
Continue beating for several minutes until the frosting becomes light and airy.
Step 3
Leave one cake in its pan or carefully transfer it to a large serving board.
Spread a thick, even layer of coconut frosting over the entire cake.
This middle layer should be generous—it creates the signature double-decker look and keeps the cake incredibly moist.
Step 4
Carefully place the second cake directly on top of the frosted layer.
Press very gently to secure it without squeezing out the frosting.
Step 5
Spread the remaining frosting over the top of the cake.
If desired, frost the sides as well.
Immediately sprinkle the shredded coconut over the top and sides, gently pressing it into the frosting.
Step 6
Slice into generous squares and serve.

Variations
