You can keep your gingerbread at room temperature in an airtight container for about 5 days, but trust me, it won’t last that long without getting eaten! You can also put it in an airtight container in the refrigerator for about a week, but keep in mind that the longer it’s in the cooler temps the more it’ll dry out. If you want to freeze your cake, wrap it up tight and keep it in the freezer for a few months. You can allow it to defrost in the refrigerator and then warm it up in the oven for a few minutes at 350.
