To make the lemon cream cheese glaze: Combine lemon zest, cream cheese, 1 tablespoon milk, and powdered sugar in medium bowl. Drizzle over cake.
I calculated this cake to be about 200 calories per serving with the frosting. Feel free to use your own calculations.
I do not recommend using ONLY whole wheat flour to make the cake.
Feel free to make these into muffins. They would be delicious!
