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