Good ways to store brownies?
We store them at room temperature. If only for 3-4 few days: under plastic wrap or in the microwave. If about a week: in sealed Tupperware to keep the humidity from getting to them. I don't know if the humidity is an issue for everyone or only for those of us in a very humid climate. The refrigerator will make them last even longer but they won't taste as fresh after refrigeration. Freezer: 4-6 months.

The absolute best place I've found to store brownies though is in my stomach.
