Preheat oven to 325
Grease sides of baking pan (8x8 or slightly smaller works best)
Add eggs, sweetener (honey or sugar), 2 tbsp coconut oil, and coconut milk to food processor. Blend for 45 seconds.
Add in coconut flour, baking soda and sea salt. Blend for additional 15 seconds.
Stir in walnuts by hand.
Make the swirl by blending all the ingredients (coconut oil, honey and cinnamon) in separate bowl to combine then swirl by hand into cake batter.
Pour batter into greased pan and bake for 25 minutes. Cool for 20 (if you can wait that long).
