Preheat oven to 350° F (175° C).
Line a muffin tin with 12 liners or grease each muffin indent liberally with oil or butter. Set aside.
Add almond flour, coconut flour, salt, soda, baking powder, and 1 tsp. cinnamon to a small sized bowl and use a wire whisk to mix together.
In a larger bowl, add eggs and whisk for about a minute until frothy. Add the honey, almond milk, coconut oil, and vanilla extract and whisk until mixed well.
Add dry ingredients into bowl of wet ingredients and whisk until just combined and incorporated.
Stir coconut sugar and 3 tsp. cinnamon together in a small bowl.
Spoon muffin batter into prepared muffin tin, filling each hole half full.
Sprinkle about 1 tsp. of the cinnamon sugar mixture onto the batter in each half filled muffin. Top each one with remaining batter.
Insert a butter knife into each muffin's batter and draw an "S" to lightly swirl making sure the knife is only inserted half way down. Don't over swirl!
Sprinkle remaining cinnamon sugar mixture on top of the batter for each muffin.
Place muffin tin in oven and bake for about 18-22 minutes until muffins are cooked through (if needed, test by sticking a toothpick into the center - it will come out mostly clean when muffins are ready).
Pull muffins from oven and let cool in the pan for 10 minutes before removing and letting cool completely on a wire cooling rack.
