I have been waiting for it for a long, long time for this Buckeye Cake. Let me tell you, it was worth the wait.
In a large bowl using a handheld mixer or stand mixer with paddle attachment, cream together the butter and sugar until light and fluffy and lighter in color.
Add the dry ingredients 1/2 cup at a time to the wet ingredients in your mixer bowl until incorporated, about 2 minutes.
Stir constantly until the chocolate chips are melted and the mixture is smooth. Do not allow to come to a boil.
