Preheat the oven to 350 degrees Fahrenheit.

Stir together the almond flour, baking powder, baking soda, sea salt, and cinnamon in a bowl (dry ingredients).

Whisk together the egg, coconut oil, pure maple syrup, and vanilla extract in a separate bowl (wet ingredients).

Pour the dry ingredients into the bowl with the wet ingredients and stir until combined. The dough will be very sticky. This is normal!

Stir in the chocolate chips and chopped walnuts until they are well-incorporated throughout the dough.

Scoop heaping mounds of cookie dough onto a non-stick baking sheet. Note: The dough will not spread much during the baking process and will maintain the same shape throughout. For this reason, form the dough into the shape you would like to end up with.

Bake 8 to 12 minutes (I do 10 on the dot), or until the edges of the cookies are golden brown. Remove from the oven and allow cookies to cool a couple of minutes before transferring them to a wire rack to finish cooling.
