One of my favorite things to do in the kitchen is bake a new batch of brownies. Nonetheless, baking brownies correctly is a crucial skill for every baker to master. My years of baking expertise have taught me that things don’t always go as planned in the kitchen.

While I was in the midst of making the brownie batter, I realized I didn’t have enough time to complete baking my brownies. This raised a few questions for which I needed solutions. Is it possible to freeze brownie batter? How do I properly freeze my unbaked brownie mix?

Brownie batter can be frozen without losing its consistency. Place the unbaked brownie mix in a freezer bag and on a baking sheet. This will help the batter to freeze flat and evenly. To avoid freezer burn, place the batter in a disposable pan and cover it with foil.

I’ve cooked hundreds of brownies for various occasions during my baking career. Understanding how to keep my unbaked brownie mix’s integrity saved me a lot of time over the years. This is why I’m going to give you a few extra pointers on how to properly freeze brownie batter.

Brownie Batter Freezing Instructions

If you want to freeze your brownie batter for a limited period of time, use a freezer bag. Place the prepared brownie batter in a freezer bag and spread it out down the length of the bag. This will keep the batter smooth and flat throughout the freezing process.

After that, remove any surplus air from the bag and seal it securely! Removing all of the air from the freezer bag may help avoid oxidation of the brownie batter. Even if the food is frozen, oxidation might cause it to deteriorate quicker.

*Removing all air from the freezer bag and closing it completely can help avoid freezer burn on your brownie batter*

To keep the batter’s form flat, use a cookie sheet. In order to absorb any extra moisture that may build, I also lay a paper towel between the sheet pan and the freezer paper. Fill a flat sheet pan halfway with brownie batter from a freezer bag.

Although less ideal, another method for freezing brownie batter in the short term is to pour it in a disposable pan and cover it with aluminum foil or freezer paper. Again, this will keep the batter from suffering freezer burn.

How long can brownie batter be frozen?

Brownie batter may be frozen for 12 to 18 months without losing its freshness. Place the unbaked brownie mix in a freezer bag and squeeze out any extra air. This will help prevent long-term oxidation of the brownie batter and make it safe to consume.

As you may be aware, air is the enemy of every food. Air oxidizes enzymes in food, resulting in food deterioration. The most critical step in keeping your batter-filled freezer bag fresher for longer is to keep it airtight.

Does freezing brownies destroy them?

As a general rule, brownie batter may be frozen without compromising its freshness. Place the unbaked brownie mix in a freezer bag and squeeze out any extra air. Put the frozen bag on a baking sheet. This will help the batter to freeze flat and evenly.

Normal brownie batter has the following ingredients:

  • Flour
  • Eggs
  • Cocoa Powder
  • Sugar
  • Oil or butter

These important components have a propensity to freeze well and retain their freshness over time.

How should frozen brownie batter be thawed?

Place the frozen brownie batter in the refrigerator after removing it from the freezer. Let for several hours or overnight thawing. While preheating the oven, place the batter on the counter for 20 minutes or until room temperature. This slow temperature rise keeps the batter fresh for baking.

I would advise covering the frozen brownie batter with extra paper towels after placing it in the freezer bag. While the frozen batter will be thawing for many hours in the fridge, the paper towels will assist absorb any extra water that may melt over time.

This will keep your brownie batter fresh while also keeping your fridge clean.

How long can brownie batter be stored in the refrigerator?

As a general rule, homemade brownie batter should keep in the refrigerator for 7 days without losing freshness. Place the unbaked brownie mix in a freezer bag and squeeze out any extra air. This will help avoid long-term oxidation of the batter and make it safe to consume.

If you want to bake your batter the next day, refrigerating the batter is the best alternative. That will bring out the chocolate taste of your brownie mix much more than leaving it in the cupboard.

Although refrigerating your brownie batter for more than a few days might help keep it fresh, I recommend freezing it instead! Freezing the batter for many days might help it keep its freshness for longer.

Having frozen brownie batter ready to bake provided me the confidence I needed to complete the brownies on time for a function!
