How to Freeze Brownies

Here are two ways you can freeze brownies. 

1. The Full Tray

Brownies’ out, cooled, knife’s ready. Hold on, before you cut your tray of brownies, are they for a special occasion on a later date? Because if so, you might want to freeze the whole slab.

Not only is it easier and more efficient to freeze the entire slab of brownie, but doing so can help the brownie retain moisture better and prevent freezer burns. You’ve got the hard, crunchy outside layer to protect your brownie with less surface exposed to air. 

To freeze a full tray of brownies, let the uncut slab cool down completely. Wrap your brownie in plastic wrap. Be generous with your plastic wrap as you want to cover every corner, this is not the time to be stingy.

For extra protection from freezer burn and oxidation, wrap another layer of aluminum foil over your plastic wrap-covered brownies. Once you’re ready to serve your brownie, you can simply remove the wrapping, thaw, or reheat your brownie in the oven. 

Note that with this method, you’ll have to reheat the whole slab of brownie before you’re able to cut into it. Brownies contain a lot of chocolate and butter which will harden them and make them difficult to cut through frozen.

2. Individually

While freezing the entire slab is an efficient way to freeze the brownies, freezing them individually might be more efficient when it comes to defrosting them. 

You might want to quickly grab a slice for a friend or to snack on at work without having to wait for a whole slab of brownie to thaw. 

Once you’ve cut up your brownies into square slices, wrap them individually in plastic wrap. An optional step here is to wrap them in foil. After that, you can place your individual brownie pieces in an airtight container or a freezer-safe bag and put them in the freezer. 

Freezing your brownies this way gives you easy access to each individual piece. Once you’re ready to eat them, simply defrost brownies at room temperature or reheat them on a tray. It shouldn’t take long. 

Can You Freeze Brownies with Frosting

If you are worried that your frosted, peanut butter swirled, or rocky road brownies can’t be frozen, don’t be. You can freeze brownies with toppings and it’s almost just as simple. 

Peanut butter or cheesecake-swirled brownies can be frozen just like regular brownies. The swirled design lays flat on the brownies and by the time they come out of the oven, they should be completely smudge-free. 

If your brownies are topped with marshmallows, nuts, pretzels, or whatever else one puts on brownies, simply wrap your brownies carefully trying not to crush their toppings. 

After that, you can rest assured that your brownies will be just as good once they’re reheated or thawed because most of the ingredients you add to your brownies won’t change in texture in the freezer. 

For buttercream or ganache frosted brownies, you want to avoid wrapping them right away because that can mess up the beautiful designs. Instead, chill your brownies in the fridge so that the frosting can harden. 

After that, wrap your brownies in plastic wrap and place them in a freezer-safe ziplock bag, freeze away. Thaw your brownies overnight in the fridge for best results.
