Preheat your oven to 350°F.

Place the frozen berries directly into your baking dish (such as a pie dish or 8x8-inch pan).

Add the jam and coconut sugar to the berries, mixing until each berry is coated. Set aside.

In a medium mixing bowl, combine oat flour, oats, ground flax, olive oil, and maple syrup, stirring until a thick crumble forms.

Using your hands, crumble the mixture over the berries until they are evenly coated.

Bake for 30 minutes or until golden brown.

Allow it to cool for 10 minutes before serving. Enjoy warm with a dollop of vanilla ice cream or coconut whip cream!
