This is similar to a Family Time recipe. I used 1/2 c yogurt (I used peach because I didn't have any plain) for the sour cream. It is actually very good and moist.
The cakes flavor is great! However, even though I followed direction to the letter this did not come out as described at all! Everything looked well until the timer went off! I had out in the oven a beautiful crumbcake. Light fluffly at least 1" layer of fine crumbs all ovar the top. What came out was a cake that was done but no crumbs at all. They had all gone to the bottom where the butterfinger particles all carmelized and made cutting the cake quite difiicult. Looked awful and difficult to sevre but good flavor.
I tried your butterfinger cake recipe, because it sounded just what I was craving and it was exactly what I needed. It was great I will be making it for a partylite candle party to pass on your delicious coffee cake. Thank you!Nancy D.
