In a mixing bowl, combine the oat flour and vanilla protein powder. Mix well until they are evenly combined.
To the dry mixture, add the unsalted creamy cashew butter, maple syrup, and vanilla extract. Stir until the ingredients start to come together.
Gradually pour in the non-dairy milk, starting with 1/4 cup, and mix. Add more milk as needed, until the dough reaches a soft and pliable consistency. The dough should hold together when pressed, but not be overly sticky.
Now it's time to bring in the festive element! Gently fold in the colorful sprinkles, ensuring they are evenly distributed throughout the dough. The vibrant specks of funfetti will add a playful touch to your protein-packed treat.
Take small portions of the dough and roll them into bite-sized balls or any desired shape. Place the cookie dough bites on a parchment-lined tray or plate. Once all the dough has been shaped, transfer the tray to the refrigerator.
