  1. Preheat oven to 350ºF and then grease two 9 by 13-inch baking pans.
  2. In a medium bowl, whisk together flour, baking powder, and salt.
  3. In a large bowl, use an electric mixer to beat butter and shortening until softened. Add sugar and beat until light and fluffy, 3 to 5 minutes.
  4. Beat in vanilla and almond extracts.
  5. Add egg whites, one at a time, beating well after each addition.
  6. On low speed, alternate adding the flour mixture and the milk to the butter mixture, beginning and ending with the flour mixture.
  7. Divide batter evenly between the baking pans.
  8. Bake until a wooden pick inserted in the center of the cake comes out clean, 35 to 40 minutes.
  9. Let the cakes cool in the pans for 15 minutes and then transfer them to a wire rack to cool completely.
  10. Level the tops of the cakes with a cake leveler or large knife.
  11. Tint 3 tubs of butter cream frosting with leaf green food coloring until you reach the desired shade of green. Scoop one-third of the green frosting into a decorating bag fitted with a #4B tip and set aside.
  12. Place one cake on a platter or cake tray. Frost the top of the layer with green frosting and set the second cake on top of it.
  13. Frosting the top and sides of the entire cake with green frosting.
  14. Place the cake in the freezer for 20 to 30 minutes.
  15. Remove the cake from the freezer and go over the frosting with a warm spatula to make a smooth surface for decorating.
