Preheat oven to 350 degrees and grease an 8x8 inch pan with coconut oil.
Combine the first five dry ingredients together in a medium bowl and stir until evenly combined. Add the rest of the ingredients and stir until evenly combined.
Pour batter into prepared pan, top with optional chocolate chips, and bake for 12-15 minutes until the center is just cooked and no longer looks wet.
Allow to cool for 5-10 minutes before serving. Serve warm.
