Leftover pancakes can be allowed to cool, then sealed in an airtight container and frozen for up to 1 month. To reheat, brush both sides of the pancakes with a little melted butter, place them in a single layer on a baking sheet, and warm them through in a preheated 350┬░F oven for about 10 minutes. Pancakes reheated in a microwave tend to toughen, but frozen pancakes can be popped into a regular toaster or toaster oven, though this produces a thicker, darker crust than oven warming. Just be careful that ΓÇ£toastedΓÇ¥ pancakes donΓÇÖt burn. Reheated pancakes will never have the tenderness and suppleness of freshly made ones but are still awfully goodΓÇöand convenient.
