First, blend the oats until they reach the fine, powdery consistency of oat flour. Pour it into a mixing bowl, then add your protein powder, collagen, salt, maple syrup, and vanilla extract, if using. Mix until combined, then pour in a splash of milk at a time until you reach a thick, dough-like consistency. Take it slow: You may need less milk than you think! Finally, fold in your dark chocolate chips.Â
