Make the Cookies:
- Preheat and Prep: Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper.
- Combine Dry Ingredients: In a large bowl, whisk together almond flour, cocoa powder, baking soda, salt, and coconut sugar.
- Add Wet Ingredients: In a separate bowl, whisk the egg (or flax egg), coconut oil, and vanilla extract. Add the wet ingredients to the dry ingredients and stir until a dough forms.
- Roll Out the Dough: Place the dough between two sheets of parchment paper. Roll out to about 1/4 inch thick.
- Cut into Shapes: Use your favorite cookie cutters to cut the dough into shapes. Transfer the cookies to the prepared baking sheet, spacing them slightly apart.
- Bake: Bake for 10-12 minutes, or until the edges are set. Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
Make the Chocolate Buttercream:
- Cream Butter: In a mixing bowl, beat the softened butter (or vegan buttery stick) with a hand mixer until creamy.
- Add Dry Ingredients: Add cocoa powder and powdered sugar, mixing on low speed until combined.
- Add Vanilla and Almond Milk: Stir in the vanilla extract and 2 tablespoons of almond milk. Gradually add more almond milk, 1 tablespoon at a time, until the frosting reaches your desired consistency.
Assemble the Cookies:
- Decorate: Spread or pipe the chocolate buttercream onto cooled cookies. Top with sprinkles, if desired.
- Serve: Let the frosting set for a few minutes before serving.
