Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
In a large bowl, whisk together whole wheat flour, almond flour, coconut sugar, baking powder, and salt.
1.5 cup whole wheat flour, 0.5 cup almond flour, 0.25 cup coconut sugar, 0.5 tsp baking powder, 0.25 tsp salt
Cut in the cold butter (or coconut oil) using a pastry blender or your fingers until the mixture resembles coarse crumbs.
0.5 cup unsalted butter
In a separate bowl, whisk together the egg (or flax egg) and vanilla extract. Add to the dry ingredients and mix until just combined. Add milk, one tablespoon at a time, until the dough comes together.
1 large egg, 1 tsp vanilla extract, 2 tbsp milk of choice
Wrap the dough in plastic wrap and chill for at least 30 minutes.
On a lightly floured surface, roll out the dough to about 1/4 inch thickness. Use Christmas cookie cutters to cut out shapes.
Place the biscuits on the prepared baking sheets and bake for 10-12 minutes, or until the edges are lightly golden brown.
Let the biscuits cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely.
Once cooled, decorate with sugar-free icing, natural food coloring, and sprinkles, if desired.
