After spending your entire day baking, the last thing you want is for improper storage to undermine all your hard work. Freezing is the most common way to store baked goods long term. Ideally, you want to be sure your baked goods are cooled completely before storing.
Breads or cakes without frosting can be stored in the freezer for about 3-4 months. Wrap at least half of the top of the baked item in a cloth towel and then wrap well in plastic. The cloth towel will absorb the extra moisture during thawing. To use aluminum foil, you must first wrap the baked good in parchment paper, then foil. After the cake is wrapped in foil, place inside plastic bag for added protection.
Frosted cakes must be frozen unwrapped initially until the frosting gets hard. Then the cake should be wrapped in plastic. When ready to thaw, unwrap the cake and leave at room temperature until thawed.
Cookies must be stored with like varieties. For example, you cannot store peanut butter cookies with sugar cookies, the flavors will mingle and you cannot store moist cookies with crisp cookies. Brownies can be wrapped individually or as a unit prior to cutting.
