Preheat oven to 350°F. Grease an 8x8 inch pan with coconut or olive oil and set aside.
In a large bowl, combine all crust/crumble ingredients together until well mixed.
Add 2/3 of the mixture to the 8x8 pan and press evenly onto the bottom. Set remaining crust/crumble mixture aside to use for crumble topping.
Bake crust at 350ºF for 10 minutes. Remove crust and set aside.
While crust bakes, add all ingredients for the berry filling into a medium sauce pan. Stirring often, bring filling mixture to a low boil, breaking up the berries. Once the mixture starts to boil, turn heat down to low and let simmer for 10-15 minutes. Continue stirring often. (Berries will start to thicken.)
Pour thickened berry filling on top of baked crust. Spread the rest of the crumble mixture over the top of the berry filling.
Bake for 10 minutes then remove from heat.
Let cool for 20 minutes before placing into the fridge for at least 2 hours to let the filling set. Slice and enjoy!
