To keep hot waffles warm, place them in a 200°F oven on a wire rack.
Do not open the waffle maker until there is no more steam.
Make sure not to overfill the waffle iron.
Fill it in the center of the spot and do not go all the way to the edges, or it will overflow.
Don’t overmix the batter. Mix it just until there are no more lumps.
Let the waffle iron heat back up after every few waffles and check to see if it needs more oil.
