Rhubarb Crunch

This is a yummy summer dessert. We always had a rhubarb patch to have fresh rhubarb pies and bars in the summer.

1 cup flour, sifted
1 cup brown sugar
½ cup butter, melted
1 tsp. cinnamon
¾ cup oatmeal
4-5 cups rhubarb, diced
1 tsp vanilla
1 cup sugar
2 Tbsp. cornstarch
1 cup water

Mix together flour, brown sugar, butter, oatmeal and cinnamon. Press half the crumbs into well greased 9 x 9 baking pan. Cover with rhubarb. Combine sugar, cornstarch, water and vanilla. Cook in saucepan until thick. Pour over rhubarb and top with remaining crumbs. Bake in 350۠۫ F oven for one hour.
