Note: I tested this recipe using “real” butter, sour cream and milk. However, the cake tends to fall when using these conventional dairy products. I suggest lowering the amount of “real” sour cream to ¼ cup. Then, depending on your oven, aim for the longer baking time, 40 minutes rather than the 38 minutes.
