Rich Rustic Rhubarb Squares
Adapted from the Rosie's Bakery All-Butter, Cream-Filled, Sugar-Packed Baking Book. These bars have a simple whole wheat vanilla shortbread crust and are piled high with diced fresh rhubarb in a light egg-flour custard. Not too sweet, they're a great addition to the backyard BBQ.
I brought these to my Reach for the Top Reunion and they were a HIT!
