When I do pancakes I insist people eat them as I finish them. Putting them in the oven isn't good. They don't taste the same.
One tip, if you have extra batter, go ahead and make the extra pancakes, let them cool, and then store them in the freezer in a zip loc. Pull them out some morning within 2 weeks, cut them in half, and put them in the toaster. Still good and slightly toasted.
