COFFEE CAKE
Preheat the oven to 350 F and line or grease an 8x8 baking dish.
In a separate bowl, mix together the wet ingredients: coconut oil, eggs, maple syrup, vanilla, apple cider vinegar and lemon juice.
Gently combine the wet and dry ingredients together with a spatula.
Toss and coat the blackberries in 1-2 tbsp tapioca flour to prevent them from sinking to the bottom of the cake
Gently fold the blackberries and the rest of the lemon zest into the cake batter.
Pour the cake batter into the baking dish and then layer the crumbles on top (use your hands to combine smaller crumbles together to create larger pieces).
Bake for 30 - 32 minutes or until a toothpick comes out clean.
Allow the coffee cake to cool on a cooling rack. Drizzle some melted coconut butter with maple syrup. **
Slice and enjoy it!
