Preheat an oven to 350 F. Begin with room temperature butter and cream cheese. Cream the butter and cream cheese together in the bowl of a stand mixer fitted with a paddle attachment, for 1-2 minutes.
Next, add the sweetener, almond flour, baking powder, kosher salt and peppermint extract. Beat again until well blended for about 1 minute.
Divide the dough into three parts and place them into separate bowls. Color one bowl with a few drops of green food coloring and another bowl with a few drops of red food coloring. Start with a little at time and add more as desired.
Place each dough side by side on a piece of parchment paper into a rough log shape. Freeze for 5 minutes until chilled. The dough should not be hardened, just firmer and easier to handle.
Remove the log from the freezer. Pick it up and slap it down gently. Repeat this process turning it on all sides to form a log shape that is roughly 12” long. Cut the log into 16 equal pieces. Roll each into a ball and then place them on a baking sheet several inches apart.
Use a measuring cup or a cup with a flat bottom to press each ball into a round cookie that is about ¼” thick. Press the bottom of the measuring cup or flat cup into some granulated sweetener and then press the cookie. This will help the cookie from sticking and give the cookie a nice crispiness after baking.
Bake for 8 minutes or until the cookies are set with barely any browning on the outside edges. Allow them to cool completely before removing them from the baking sheet to a cooling rack. Store in an airtight container.
