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 forms.
03 - Gradually add milk, 1 tablespoon at a time, mixing continuously until the dough becomes firm yet pliable and holds its shape when pressed.
04 - Gently fold in the rainbow sprinkles until evenly distributed throughout the dough.
05 - Roll the dough into 1-inch balls. Optionally roll each ball in additional sprinkles for decorative coating.
