Well, damn. Stacy Zane made a Treebeards Buttercake and got EOW Nation drooling. Wrote commenter Trish:

I’ve had that recipe taped to my refrigerator door for years, but I can’t bring myself to make it because I know I’ll eat the whole pan in one sitting and immediately make another.  Kudos to you for even letting it sit long enough to take a picture!  I’ll stick to budgeting this treat one square at a time with each visit to Treebeards.

Right on, Trisch. Let someone else dole out the portion, because otherwise a whole pan sounds about right.
