Butterfinger Cake

The once or twice a year that my immediate fam all gathers together is all the excuse I need to test-drive a new overly indulgent layer cake recipe. Something about assembling layer upon layer of cakey, gooey, crunchy, rich goodness just makes my heart happy and my house smell saccharine sweet.

This year was no different and the recipe on trial was that of a Butterfinger cake. That’s a chocolate, sour cream cake with a nice heavy layer of Butterfinger peanutbutter butter cream. Since it’s Thanksgiving, I made some acorns out of mini Nutter Butters and Hershey Kisses.
