A pancake warmer is one of those silly things that you always think would be "nice to have." And they are kind of clever. But again, you have to ask yourself, how often do you really make pancakes? And how many pancakes are you making at a time so that you'd need a whole piece of stoneware to keep them warm? Usually, pancakes get eaten pretty quickly!
Plus, this is another one of those kitchen items that will take up a lot of space in your cabinets. So, instead of registering for one, try putting your cooked pancakes on a baking sheet in a warm oven while you cook the rest. Or, if you're really a pancake fiend, register for a griddle with a warming drawer built in.
