Heat oven to 350 and line a 9x13 inch baking pan with parchment paper.
Next, in a small saucepan add the filling ingredients and bring to a boil over medium heat. Reduce heat and simmer for about 10 minutes, stirring and breaking up the berries with the back of the spoon. Once the filling has thickened, remove it from the heat and set aside.
Then, in a large mixing bowl, whisk together the dry ingredients - flour, oats, coconut sugar, baking soda, and salt. Once they are combined, stir in the coconut oil and stir again to incorporate it.
Next, press in just over half of the crust mixture into the lined baking dish. Pressit in well to make a nice even base for your bars.
Then, pour in the strawberry filling over the base and spread it out evenly.
Finish by sprinkling the remaining crumble mixture over top of the strawberry layer.
Bake for 30 minutes, until the top is golden brown.
Cool completely in the pan before removing and slicing. About 1 hour.
