Easy apple rhubarb crunch with oats dessert is amazing! Using fresh or frozen fruit with an Old Fashioned oatmeal crisp topping it's great for brunch, breakfast or a light dessert.
Mix together your rhubarb, sugar, cornstarch and diced apples gently so all fruit is coated well.
Preheat oven to 350 degrees and spray 8x8 pan with non stick spray.
Pour fruit mixture into pan.
Mix together melted butter, oats, brown sugar, flour and cinnamon in a bowl until everything is combined well. Sprinkle this on top of your fruit mixture in your pan so it is spread evenly across.
Put in oven for about 40-45 minutes or until top is lightly golden brown. Allow to sit to thicken up a bit. Serve with ice cream on top if desired.
