In a 8x8 pan place 3 C of frozen berry mix. I sprinkled mine with a slight dusting of RxSugar because the berries were sour.

In a bowl mix together 6 Tbs butter, 1 tsp cinnamon, 1 C oats, & 2 scoops of vanilla protein powder. Place the crumble mixture on top of the berries. Bake at 350 for 15 min or until golden brown. I topped mine off with vanilla bean ice cream!
