My favorite is one that I only made once. I made a basic 2-layer Angel's Food Cake recipe, in the standard 9" round cake pan, but substituted Grade B maple syrup for the sugar. I then made a simple butter-cream icing, again using the maple syrup, and pecans. I cut each layer into three layers, and stacked them all with the icing between, and of course, icing to cover.
It was amazing. The only reason I don't make it more often is that my DW doesn't care for maple. I ask you, how is that even possible?
