Preheat oven to 350°F. Line a baking sheet with parchment paper.
In a small bowl, combine Paleo Baking Flour, coconut sugar, baking soda, and salt; set aside. In a large bowl, mix together coconut oil, egg, and vanilla extract. Add dry ingredients and mix-ins and mix to combine. Dough will be dry and crumbly.
Shape about 2 Tbsp dough per cookie into a tight ball and place on prepared baking sheet; flatten slightly. Bake until edges are golden-brown, about 10–12 minutes.
To make the dark chocolate cherry cookies pictured above, add 1/4 cup dark chocolate chips and 1/4 cup chopped dried cherries.
