Add all of your cookie ingredients to a large bowl and use a hand or stand mixer to combine the dough. Alternatively, add everything to a food processor to incorporate
Place dough onto parchment paper, place another piece of parchment on top, and roll dough out to 1/4 inch thickness
Use a small cookie cutter to get even cookies, and move shaped cookies onto a baking sheet lined with parchment paper. The cookies won't spread, so no need to leave much spacing
Roll the excess dough back up and out again, and repeat until you've made cookies out of all the dough. I got 40 single cookies total
Bake at 350 for 10 min
Allow to cool completely
Gather 3 bowls
Add half of each color satchet along with 1/2 tsp water to each bowl, until colorant has dissolved
Add roughly 1/3 cup pre-made vanilla frosting to each of the three colored bowls and whisk / use a hand mixer until icing is smooth, fluffy, and color is vibrant and fully incorporated
Place each colored icing into a piping bag, and pipe onto the center of half the cookies
Place remaining cookies on top and press down slightly
You can now add your candy eyes if using (see homemade candy eye instructions in the post above)
Enjoy as is, or refrigerate for firm cream filling
