In a large bowl, beat the ghee on high with a hand mixer, until creamy.
Add the maple sugar, and baking soda and beat once more until combined, scraping the sides to mix well.
Beat in the egg and vanilla.
Add the flour and mix with a rubber spatula until mostly combined, then finish mixing with the hand mixer.
Place a large piece of parchment paper on the counter and place the ball of dough on it.
Flatten it out and place another piece of parchment paper on top, then carefully roll it out to 1/4" thickness with a rolling pin. Don't press too hard or the parchment paper will stick. Remove top piece of parchment.
Use cookie cutters to cut out festive shapes, then carefully transfer them to a parchment-lined baking sheet with a spatula.
Space cookies 1-2" apart before baking on the top rack for 10-12 minutes, until edges become lightly golden.
Meanwhile, repeat cookie cutting process with remaining dough by combining dough scraps into a ball and rolling it back out. Bake remaining cookies.
Allow cookies to cool before transferring them to a serving dish. Frost with vanilla buttercream frosting for best results.
