What better way to celebrate a birthday than with cake?! This is a classic vanilla cake with buttercream and added a bit of food coloring for patriotism! I use Martha Stewart's yellow cake recipe and substitute flour for Pamela's cup-for-cup gluten free flour. The food coloring affected the texture of the cakes so next time I'll have to play around and see why that is, but it still tastes delicious :) Simple as that! Happy fourth everyone!
