how to make Sour Cream Rhubarb Cake
You cream the butter and sugar, add eggs, sour cream, and vanilla. Then you fold in dry ingredients and the rhubarb. The batter goes into a 9×13 pan and bakes about 30–35 minutes. The method is similar to a simple sheet cake such as Cherry Chip Cake, but with fresh fruit folded in.
