Grapefruit Cake with Cream Cheese Frosting

Grapefruit Cake with Cream Cheese Frosting (I just bought the frosting already made)

1 1/2 cups of sifted cake flour, 3/4 cup of sugar, 1 1/2 tsp. of baking powder, 1/2 tsp. of salt, 3 large eggs separated, 1/4 cup of vegetable oil 1/4 cup of water, 3 tbsp. of grapefruit juice - I used pink grapefruit juice, 1/2 tsp. of finely grated lemon zest, 1/4 tsp. of cream of tartar.

Preheat the oven to 350 degrees and heavily Pam spray a 9X2 inch round cake pan. In a large bowl mix together flour, sugar, baking powder and salt. In a medium bowl, whisk together the egg yolkds, oil water, grapefruit juice, and lemon zest until smooth. Whisk in the flour mixture.

Then beat the egg whites and the cream of tarter with an electric mixer in a medium bowl until stiff peaks start to form. Whith a rubber spatula, gently fold the egg whites into the yok mixture, until just blended. Pour into the prepared pan.

Bake for 25-30 minutes, or until the cake springs back when touched lightly in the center. Invert the cake, still in the pan, and cool.

Once cool cut the cake in half horizontally.

Spread the Cream Cheese Frosting on the bottom half of the cake. Put the cake together and ice the top and all around the sides and decorate with slices of grapefruit.
