Margarita Cake Layers
  1. Pre-heat oven to 350 degrees
  2. Grease and flour two  9-inch round pans and line bottoms with parchment paper
  3. In a medium bowl whisk together the egg whites, whole egg, ¼ cup of milk and vanilla; set aside
  4. In the large bowl of an electric mixer use your fingers to rub the lime zest into the granulated sugar, this will help to release the flavor from the zest; then, with the paddle attachment, combine the sugar / lime zest, sifted flour, baking powder and salt together on low speed for just 30 seconds
  5. Add the butter and shortening; mix on low speed for 30 seconds; add remaining milk and mix again on low speed until just moistened, about 30 seconds
  6. Increase mixer to medium speed and beat for 1½ minutes
  7. Scrape the sides of the bowl add the egg/milk mixture in 3 separate batches; beat on medium speed for 20 seconds after each addition; do not overmix
  8. Divide the batter into prepared baking pans; bake for 29-32 minutes or until a toothpick comes out clean from center of each layer
  9. Set cake layers aside to cool for 10 minutes then carefully remove each layer from pans; run a knife around the edge of each layer for easier removal
  10. Once cake layers are completely cooled, use a serrated knife to carefully cut each layer in half horizontally, creating 4 cake layers; set aside and make buttercreams
Margarita Frosting
  1. Beat butter and cream cheese in the bowl of an electric mixer on high speed or until light and creamy
  2. Add 1 cup of powdered sugar and mix on low speed for one minute; add additional cup and mix on low for one minute again; add remaining sugar, tequila, lime zest and salt
  3. Mix on low speed for one minute and then scrape the sides of the bowl; beat on high speed for several minutes or until buttercream is light and fluffy
