Ingredients for filling:
1 C flour
¾ C rolled oats
¾ C brown sugar
½ C melted butter
1 t cinnamon
Ingredients for crumble layer:
¾ C granulated sugar
2 T cornstarch
1 t vanilla
1 C water
4 C chopped rhubarb
Method:
Prepare the crumble layer by mixing the flour, oats, brown sugar, melted butter and cinnamon in a bowl. Press half in a 9 X 9 baking pan. Reserve the remaining half of crumble for the topping.
Prepare the filling layer by bringing all the ingredients to a soft boil: sugar, cornstarch, vanilla, water and rhubarb. Allow to cook and thicken – but not too much – it’s OK that it’s very watery.
Pour rhubarb over crumble layer. Top with remaining crumble mixture.
Bake 350 degrees for about 45 minutes.
