I used to hate rhubarb. You couldn't pay me to eat it. My mother-in-law gave me so much rhubarb, I looked for a way to make it other than pie. I found this recipe, made some adjustments, added my crumb topping that I put on everything, and viola'! It smelled so good baking that I had to taste it. I loved it! I leave a piece in my guest(s) room(s) when they arrive at my B&B. Everyone loves it and always ask for more.
11. Mix all dry ingredients in a bowl. Add wet ingredients except topping (below) into a bowl. Stir until all ingredients are moistened. Spread into a 9" X 13" greased rectangular pan (batter will be thick). (If you have one, I use a 10" square pan - makes cake thicker - bake the longer time)
2. Mix topping ingredients together. I pulse in a food processor. Sprinkle topping evenly over batter. Bake at 350 degrees for 50-60 minutes. Serve warm or at room temperature. Yum!
