Preheat oven to 350°
In a large mixing bowl add your dry ingredients (flours, coconut sugar, cinnamon, salt, and baking soda)
Whisk your dry ingredients together until evenly combined.
Using the back of a spoon, form three caves (depressions) into the mix.
In one of the caves pour the coconut oil. In the second pour the vanilla and vinegar. In the third one pour the maple syrup.
Next, begin mixing the wet and dry ingredients. The mixture will be lumpy and difficult to mix.
Slowly begin adding in the water while mixing.
Mix thoroughly until a thick pancake-like batter consistency is achieved.
Pour batter into coconut oil-greased 8 x 11 inch pan.
Bake at 350° between 30-35 minutes or until a toothpick comes out clean.
When done baking, let the cake rest inside the oven for 20 minutes.
