Brownies have a lot of flavors packed into a small package. Unlike cakes, brownies generally do not contain leavening agents such as baking soda or baking powder.

There is a fundamental difference between a chocolate cake and a brownie in how much sugar, butter, and flour they contain. As such, brownies are bar cookies rather than cake. Bar cookies are generally eaten by hand, as opposed to with utensils.

It is hard not to smile and be upbeat when you smell and taste freshly baked brownies. How can you preserve brownie batter so that you can enjoy chocolatey goodness whenever you want?

Can you freeze Brownie Batter? It is possible to freeze brownie batter for 12 to 18 months before eating. Unbaked brownie batter freezes very well because it does not contain leavening agents. The brownie batter can be frozen, thawed, and baked the same way as a freshly prepared batter.

There is no question that brownie batter freezes well. But what is the best way to go about it? There are no complex steps; it is easy to do and can be frozen in a variety of ways to meet your needs.

How to Freeze Brownie Batter

The brownie batter can be frozen in any container if you want to prepare them ahead of time and use them later. To ensure the best flavor, it’s best if the batter is frozen immediately after preparation.

Step 1: Portion and Pre-Freeze the Brownie Batter

Prepare the brownie batter by following the directions to your favorite brownie recipe. Once the batter is ready for freezing, it can be portioned into small containers (for single-serve brownies) or transferred into a baking dish.

By dividing the batter into portions, you do not have to thaw the whole batch at once. You can opt to cook just a couple of brownies at a time. Portion sizes work great for smaller households or those with dietary concerns that may not want a large batch of brownies lying around.

Brownie batter can be spooned into a vacuum seal or Ziploc bag and frozen. Remove all excess air from the bag before sealing. We prepare the batter this way if we plan on baking it in muffin tins to create brownie sundae bowls.

Step 2: Storage

You can store a frozen brownie batter for up to 18 months. The batter will have to be protected from the harsh air of the freezer for that length of time. If you don’t plan to consume the brownies within 30 days, we recommend that you vacuum seal the batter.

Step 3: Freezing

If you haven’t already, you can label the freezer bags once the brownie batter is packed well and sealed. Make sure you state the contents of the freezer bag and the date you froze it.

Freezing Brownie Batter into Disposable Pans

Generally speaking, we prefer to freeze the entire batch in 8″x8″ square foil baking pans. Spread the batter evenly throughout the baking dish, then apply a piece of plastic wrap or parchment paper on the surface of the batter.

Slide the entire pan into a gallon-sized Ziploc bag, remove as much excess air as possible and seal. Label the brownie batter with the finishing instructions for the recipe.

For example, bake at 350°F for 24-28 minutes. Once the bag has been properly sealed and labeled, place it in the freezer.

Recommended Containers for Freezing Brownie Batter

When it comes to freezing brownie batter, the best container options are those that are airtight and resealable. This is important in order to preserve the freshness of your batter as long as possible. Here are a few recommended containers for freezing brownie batter:

  • Reusable silicone bags: These reusable bags come in a variety of sizes and shapes, which makes them perfect for storing individual servings or larger quantities of brownies. They also feature an airtight seal which helps prevent freezer burn.
  • Plastic wrap with foil lid: If you want to save space (or don’t have enough room in your freezer), plastic wrap can be used in combination with aluminum foil lids to create a semi-airtight environment for food storage. Just make sure to use multiple layers of plastic wrap, and press the lid down firmly against the rim of your pan/container before freezing!

How to Thaw Brownie Batter

There is no big secret to thawing frozen brownie batter.

If you chose to freeze brownie batter in Ziploc or vacuum seal bags, it could be left in the refrigerator overnight to thaw. Then transferred to a baking dish and baked according to the directions of the recipe.

Brownies baked in this manner will be slightly more dense and fudgy.

How to Bake Frozen Brownie Batter

After you have frozen the brownie batter in disposable pans, you can place the pans into the oven straight away, without thawing.

When you want brownies quickly, you can bake the frozen brownie batter in a preheated oven at the temperature provided in the recipe instructions. You’ll need to add about 5-10 minutes more baking time to allow for the frozen batter.

When done, the brownies should pull away from the edges of the pan, and the center should be set but not dry or stiff.

How to Recognize Spoiled Brownie Batter

Brownie batter can go bad. Spoiled brownie batter will develop an odd or off odor, flavor, and appearance. Mold on a brownie batter is a sure sign that it has spoiled and shouldn’t be baked or consumed.

Benefits of Freezing Brownie Batter

Freezing brownie batter can be a great way to save time in the kitchen. Here are some of the main benefits associated with freezing brownie batter:

  • Longer Shelf Life: Freezing brownie batter helps to preserve its freshness and texture for much longer than if it was left at room temperature. This means that you can make your brownies ahead of time, and simply thaw them when you’re ready to bake!


  • Versatility: With frozen brownie batter, you can easily switch up flavors or shapes without having to start from scratch each time. Plus, they freeze well in any type of container — whether it’s a muffin tin, plastic wrap, or resealable baggie.


  • Economical: Purchasing pre-made brownie mixes can be expensive and not always as delicious as homemade. Freezing your own batter cuts down on food waste and allows you to use up all the ingredients at once.

Overall, freezing your own homemade brownies is a hassle free way to diversify your baking repertoire while saving time and money in the process!
