Enjoy the bounty of the season with these salty, sour, and sweet Rhubarb Bars!
Cook this mixture until it is thickened and bubbly on low to medium-low heat. It usually takes about 20 minutes.
Grease a 9 x 13 pan. Place 1/2 of the crumble mixture in the bottom of your pan and pat it down firmly. Now pour your rhubarb sauce mixture over the bottom crust. Place the remaining crumble mixture over the sauce and pat down, slightly. Bake at 375 degrees for 30 minutes.
