For this margarita cake with key lime cream cheese frosting, you can even make an adult version by adding three shots of either rum or tequila to the icing! I make this cake for parties and on birthdays.
Ingredients
1 (15.25 ounce) package white cake mix
3 large egg whites
1 (10 fluid ounce) can frozen margarita mix (such as Bacardi), thawed
2 tablespoons vegetable oil
2 tablespoons lime juice, divided
1 tablespoon grated lime zest
1 (8 ounce) package cream cheese, softened
½ cup unsalted butter, softened
1 tablespoon grated lemon zest
5 cups confectioners’ sugar
Directions
Preheat the oven to 350 degrees F (175 degrees C). Grease and flour a 9×13-inch cake pan.
Beat together cake mix, egg whites, margarita mix, oil, 1 tablespoon lime juice, and lime zest in a large bowl until smooth and well combined. Pour batter into the prepared pan.
Bake in the preheated oven until a toothpick inserted into the center of cake shows moist crumbs, 30 to 35 minutes. Cake will be very moist. Cool completely in the pan, about 1 hour.
Beat together cream cheese and butter in another large bowl until light and fluffy. Stir in remaining 1 tablespoon lime juice and lemon zest. Beat in confectioners’ sugar, one cup at a time, scraping the sides of the bowl thoroughly with a spatula after each addition. Spread frosting over cooled cake.
Cook’s Note
You may use your favorite 1-2-3-4 cake recipe if you’d prefer to make this cake from scratch.
To make a layer cake instead, grease and flour 2 (8-inch) round cake pans. Pour batter into the prepared pans and bake as directed in Step 3. Cool cakes in their pans for 15 minutes before inverting onto a wire rack to finish cooling. Make frosting as directed.
