Preheat oven to 350F. Grease a loaf pan with coconut oil and line it with a strip of parchment paper long enough to create “handles” on the ends for easy lifting. Set aside.
In a large bowl, add the dry ingredients (almond flour, arrowroot starch, baking powder, cinnamon, nutmeg and salt) and mix until well combined.
Add remaining wet ingredients (eggs, maple syrup, vanilla and olive oil) to the dry ingredients. Mix again until well combined. Set aside.
In another bowl, combine all the ingredients for the cinnamon swirl.
Pour ⅓ of the batter into the loaf pan then dollop ⅓ of the cinnamon mixture. Use a knife to gently swirl the cinnamon mixture into the loaf batter. Repeat the layering until all batter and cinnamon mixture has been used.
Place in the oven and bake for 45-50 minutes or until toothpick inserted comes out clean. If the loaf begins to brown too quickly cover and place back in the oven.
Once cooked, remove from oven and let cool before removing from the pan and slicing.
Wrap any uneaten portions and store at room temperature for 2-3 days (it will become dense the longer it's out).
