*To tell if your batter is just right, dip an Oreo into it and lift it out slowly. The batter should coat the cookie fully in a smooth, even layer without any of the Oreo peeking through. It should stick to the cookie without dripping too much. If the batter slides off or seems too runny, add a little more pancake mix and stir. If it feels clumpy or overly thick, mix in a small splash of milk to thin it out.
