1-Getting started: Getting started with this Key Lime Cake Coconut is easier than you might think, and the steps are straightforward to follow. Begin by preheating your oven to 350°F and preparing a 13×9-inch baking dish with nonstick baking spray and flour. This sets the stage for a cake that’s moist and full of flavor.

2-Mix and bake the cake: Mix and bake the cake using the 15.25-ounce box of yellow cake mix according to the package directions. Once it’s done, let it cool for about 5 minutes. In a medium bowl, stir together the 14-ounce can of sweetened condensed milk, 1 cup of coconut milk, and 6 tablespoons of key lime juice until everything blends smoothly.

3-Poke holes and add mixture: Using the handle of a wooden spoon, poke holes in the warm cake without touching the bottom of the pan. Pour the mixture over the cake, then cover and refrigerate for about 4 hours until it’s chilled.

4-Prepare the topping: For the topping, in a large chilled bowl, combine 2 cups of heavy whipping cream, 1.25 cups of confectioners’ sugar, the remaining coconut milk, and the remaining 4 tablespoons of key lime juice. Beat at high speed until thickened, then spread it over the cooled cake and top with lime zest and sweetened flaked coconut if you like. This cake tastes best when chilled and ready to serve.
