Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a large mixing bowl, combine the non-fat Greek yogurt, angel food cake mix, and vanilla extract. Stir until well incorporated.
Using a spoon or cookie scoop, portion the batter onto the prepared baking sheet, leaving space between each cookie.
If desired, sprinkle the cookies with colorful sprinkles.
Place the baking sheet in the preheated oven and bake for approximately 10 minutes, or until lightly golden brown and set.
Remove the cookies from the oven and allow them to cool on the baking sheet for a few minutes before transferring to a wire rack.
