  • 1 1/2 cups Mixed Berries thawed if using frozen
  • 2 tsp White Sugar or preferred granulated sugar substitute
  • 1/2 cup Rolled Oats certified GF if needed
  • 1/2 cup All Purpose Flour or oat flour (see note)

  • 1/4 tsp Cinnamon ground
  • 1/4 tsp Salt
  • 2 tbsp Extra Virgin Olive Oil

  • Preheat your oven to 350F
  • In a small bowl, mix the mixed berries (along with their juices if using thawed frozen berries) with the white sugar.
  • In a separate medium-sized bowl, add the oats, flour, oat bran, brown sugar, cinnamon, salt, butter and olive oil. Mix to combine.
  • In a small 6.5” cast iron skillet or loaf pan, press half of the crumble mixture into the bottom of the pan. Top with the berry mixture, then scatter the remaining crumble mixture over top.
