1.  Preheat oven to 350°. 2.  Spray a 9 x 9 baking pan with a vegetable spray like Pam. Set aside. 3.  In a medium mixing bowl, add the cake mix, 1 stick butter and 1 egg. Stir until well incorporated. 4.  Transfer the cake mix dough to the bottom of the 9x9 pan. 5.  In a large mixing bowl, add the powdered sugar, 1/2 stick of butter and juice of one lemon. With an electric mixer on medium speed, mix until the icing develops a thick consistency- about 3 to 4 minutes. 6.  Add the cream cheese to the icing and mix on medium speed until light and creamy. 7.  Add the yellow food coloring and mix until fully incorporated. 8.  Measure out 1 cup of the icing and set aside for later. 9.  Add 2 eggs to the remaining icing and mix on medium speed until light and fluffy. 10.  Using a metal spatula, spread the icing on top of the cake. (This will make the second cake layer). 11.  Bake for 28-30 minutes or until an inserted toothpick comes out clean. 12.  Allow to cool in the pan for 10 minutes before transferring to a wire rack to cool completely. 13.  Once cooled, use the reserved icing to frost the top of the cake. 14.  Garnish with lemon and strawberry slices. 15.  ENJOY!!
