I made this today for the first time but with strawberries and no sour cream for the cake base ... did not make a difference as far as I can tell .. this cake is just delicious ... was looking for coffee in the recipe but think it is just an American description of a cake to have with coffee ... main thing is, it turned out great ... although in my oven I baked it for half hour longer
