Preheat oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a large bowl, whisk together almond flour, coconut flour, cinnamon, nutmeg, ginger, salt, and baking soda.
In a separate bowl, mix melted coconut oil, maple syrup, and vanilla extract until well combined.
Add the wet ingredients to the dry and stir until a dough forms.
Chill dough for 10–15 minutes if it's too soft to roll.
Roll out dough on a floured surface to about 1/4-inch thick. Use cookie cutters to cut into festive shapes.
Transfer cookies to prepared baking sheet and bake for 8–10 minutes, or until edges are golden.
Let cool completely on a wire rack before icing.
For the icing, mix powdered sugar, vanilla, and almond milk until smooth. Pipe or spoon over cooled cookies.
Decorate with sprinkles if desired. Let icing set before storing.
