To prepare a tropical meringue cake recipe, first you need to gather your ingredients. You'll need: 1 cup of chilled whipping cream, 2 tablespoons of sugar, 1 tablespoon of vanilla extract, and 1 teaspoon of salt. Beat the ingredients together with an electric mixer until the mixture is light and fluffy. Add the egg whites and beat until stiff peaks form. Fold in the vanilla and coconut. Pour the batter into the prepared cake pan and bake the cake at 350 degrees F for 40 to 45 minutes. Allow to cool before cutting into squares.
