Preheat oven to 350 degrees F.
Melt together cashew butter, honey, and chocolate drink mix in a pot over medium heat. Stir until smooth. Add vanilla. Let cool, then stir in beaten egg (don't add before mixture cools or you will cook the egg). Stir in oatmeal blend until well combined.
Scoop a heaping teaspoon of dough and roll into a ball. Flatten onto cookie sheet (greased or parchment lined). Space cookies about 1 inch apart.

Cool and enjoy!
