Yes, I do it all the time.
One tip though--when you are making the pancakes from the cold, leftover batter, let it sit out on the counter for awhile. I find that when I cook the pancakes and the batter is still really cold, they don't cook well in the middle for some reason and can be kind of gooey.
I will generally let it sit out about 30 minutes or longer to get the chill off and then cook and they are fine.
