Add almond flour (1 1/2 cup), salt (1/2 teaspoon), xanthan gum (1/2 teaspoon), and erythritol (1/2 cup) to a food processor. Pulse several times to combine.
Add unsalted butter (2 tablespoon) and almond milk (1/4 cup), occasionally scraping down the sides of the food processor to thoroughly combine everything. Process until the dough forms into a ball.
Form the dough into 2 small balls, and press each into a disk.
Roll each disk between 2 pieces of parchment paper until 1/8" thick -- The thinner the dough, the crisper your cookies will be.
Remove the top sheet of parchment, and cut the dough using cookie cutters. If your dough is picking up off the bottom parchment, place it in the freezer for 15 minutes (this allows the butter to harden and make it easier to work with).
Place cut cookies in the freezer for 15 minutes (this makes the cookies more mobile and easier to spread out on your cookie sheet).
Preheat oven to 350 F.
Remove cookies from the freezer and spread them out on a parchment paper-lined cookie sheet.
Bake in preheated oven for 8-11 minutes. You'll know they're done once the edges are golden.
Allow your cookies to cool completely on the parchment paper before moving.
Meanwhile, melt the sugar-free white chocolates (1 1/2 cup) in the microwave, using 30-second intervals. Stir the chocolate every 30 seconds until smooth.
Divide the melted white chocolate into 2 bowls. Add food coloring or raspberry powder to one of the bowls and stir. Add more/less depending on how pink you would like the pink version to be.
Dip the cookies into the melted chocolate, switching between the white and pink. Place them on a cookie rack nested into a rimmed cookie sheet. Option to sprinkle the cookies with rainbow sprinkles.
Allow cookies to set completely by placing them in the fridge for at least an hour. Enjoy!
