Waffles are dough-based cakes cooked in a molded iron that creates a distinctive waffled pattern. They are crisp on the outside and fluffy on the inside. When serving waffles at a buffet, you'll need to make sure they stay this way. You can keep them warm and crisp for up to two hours with a warming plate and a baking sheet.
Preheat the warming plate to "high."
Lay the waffles on the baking sheet in a single layer. Stacking them on top of each other traps steam between each waffle, causing them to become soggy.
Place the baking sheet on the warming plate and cover the waffles with paper towels. The towels will keep the waffles warm without trapping steam and softening them.
Serve the waffles within two hours for the best flavor and texture.
If you need to keep waffles warm for longer periods, place the baking sheet in an oven set to "warm," or 150 degrees Fahrenheit. Serve the waffles within five hours. Don't use paper towels with this method.
