1 c quick oats
1/2 c flour (I used almond flour)
1 c brown sugar (I used coconut sugar)
3/4 tsp cinnamon
1/3 c butter
4 c diced rhubarb (could also use apples or mix fruits)

Preheat oven to 375° and grease a 9″ square baking pan.

Blend first 5 ingredients in food processor or using a pastry blender.  Spread half of this mix in baking pan.  Spread all the rhubarb out over this. Cover rhubarb with remaining dry mix.

Bake for 40 min.
