One batch of simple cream cheese frosting (link above)
Instructions
Preheat oven to 350 degrees.
Combine sugar, butter, lemon zest, lemon concentrate, vanilla extract, and eggs in a large bowl.
In a separate bowl, stir together flour, baking powder, salt, and baking soda. Slowly add dry ingredients and buttermilk to wet ingredients until a uniform batter forms.
Spray two 9 inch round baking pans with cooking spray and divide batter evenly into pans.
Bake for 20 minutes, or until a toothpick comes out clean. Allow to cool for about 30 minutes before icing.
