In a bowl add milk with your pancake mix and egg and whisk. Add vanilla and continue whisking until it is very smooth.
When skillet is hot spray with non stick spray and pour in 1/8 of your batter for a small pan or 1/6th in a larger size into the center.
Pick up the pan and swirl it so the batter coats the bottom of it. Return to heat just until the edges are starting to peel up and center is no longer wet.
Carefully use a spatula to lift up the edge and into the middle. Transfer to a plate with a paper towel on top of it.
Do this to make all the batter into crepes. Should serve immediately.
Fill with things like whipped cream with slices of fresh fruit or savory with shredded cheese and lunchmeat or warmed leftover meat. Roll or fold up and enjoy.
