White Cake with Chocolate Frosting

When I got up Sunday morning I decided to look for a white cake recipe and then add a Chocolate Frosting. I found a white cake recipe on allrecipes. It calls for milk, I used buttermilk instead. The chocolate Frosting follows the cake recipe. The cake is very nice, moist and light. Would definitely make this cake again. Due to adding the sour cream the cake should be kept in the frig. A round plate does not really fit the square cake, I will be looking for a square cake plate.
