I was so happy with how well this turned out, as I made it for my son's birthday party for lots of guests. I was told to keep this recipe! It tastes just like a whoopie pie. The filling is perfect, not excessively sweet, and the cake is moist and dense, like a whoopie pie. The only thing I changed was I used 3/4 c plain yogurt 1/2 c milk for the buttermilk (as I always do), plus I didn't have enough filling after "liberally frosting the top", so it ended up being just on the top and middle, which was just right to me. Looked more like a whoopie pie cake that way, too.
One of the best cakes that I have tried. Love it! It is a keeper, yummy!
I have made this cake a few times now, and it is always a hit. It indeed taste just like a whoopie pie. The filling is very similar to my regular whoopie pie filling. I did made a couple changes. First, to get enough filling, I doubled the filling recipe. I felt that the butter made the filling to soft so I used 1/2 butter and 1/2 shortening. To thicken the milk, I added 2 extra tbsp of flour. Perhaps this won't bee needed when it is not summer time. But when it is 90 degrees out, these 2 changes made the filling perfect.
