01 - In a large bowl, whisk together the protein powder, oat flour, coconut flour, and sea salt until evenly distributed.
02 - Add the almond butter, maple syrup, and vanilla extract to the dry mixture. Mix thoroughly until a crumbly dough consistency forms.
03 - Gradually incorporate milk, adding 1 tablespoon at a time, while mixing continuously. Stop when the dough becomes firm yet pliable and holds its shape when pressed.
04 - Gently fold in the rainbow sprinkles, being careful not to overmix which could cause sprinkles to break.
05 - Portion the dough and roll into uniform 1-inch balls. Optionally roll each ball in additional sprinkles for exterior decoration.
06 - Arrange the balls on a parchment-lined baking tray and refrigerate for a minimum of 30 minutes to allow the mixture to set completely.
