Preheat oven to 350F.

Combine the coconut flour, cacao powder, tapioca flour, coconut sugar, and baking soda together in a bowl and mix well.

Add the milk, maple syrup, oil and eggs to the bowl and mix well using an electronic hand-mixer.

Fold in the chocolate chips.

Pour the batter into an 8x8 greased/parchment-lined glass dish or greased cake pan of choice.

Bake for 35-40 minutes, or until a toothpick comes out clean.

Allow the cake to cool, then slice and serve.
