Using light cream instead of milk in crepes?
In that recipe, there are 2 cups of milk, and 2 tablespoons of butter.

The difference in fat from dairy in going from milk to light cream at 15% fat is about 3 tablespoons of fat (and therefore, about 3 tablespoons less water).

You are almost quite likely going to get a quite similar outcome if you eliminate the butter, and maybe add a tablespoon or two of water.
