Plain brownies keep for 3 to 4 days at room temperature, about 1 week in the fridge, and up to 3 months in the freezer. Keep them tightly covered. Brownies with cream cheese swirls, cheesecake layers or whipped-cream frosting must go in the fridge.
| Brownies | Room temperature | Fridge | Freezer |
|---|---|---|---|
| Plain or with chocolate chips or nuts | 3 to 4 days | About 1 week | Up to 3 months |
| Frosted (buttercream or ganache) | 2 to 3 days | About 1 week | Up to 3 months |
| Cream cheese or cheesecake brownies | No more than 2 hours | 3 to 4 days | Up to 2 months |
Room temperature or fridge?
Plain brownies taste best at room temperature, because the fridge can make them firmer and drier. Use the fridge if your kitchen is hot or humid, or if you need them to last longer. Bring them to room temperature before eating, or warm them for 10 to 15 seconds in the microwave.
How to store them
- Let them cool completely, then cover the pan tightly or move them to an airtight container.
- Don’t cut them all at once. An uncut slab stays moist longer.
- To freeze, wrap pieces individually, then put them in a freezer bag. Thaw them at room temperature.
Signs they’ve gone bad
Mold, a sour or off smell, or a very hard, dry texture. Throw out any brownies with mold.
