Freezing brownies after they are baked works too, but sometimes you just want some fresh brownies at a moments notice and do not want to resort to any brownie mixes.

I know that this trick to saving time in the kitchen is a great idea, but I wanted to show you how it actually works to bake them after freezing, so I tested that as well!

Keep reading to the bottom of the post for substitutions, ways to modify the freezing methods, and other ideas where you can use this trick as well.

Make my Low Carb Fudgy Brownies First, Here are the Essential Ingredients Needed:

• Butter; softened
• Confectioners erithrytol or other powdered low carb sweetener
• Cocoa powder
• Large eggs room temperature
• Pure Vanilla extract
• Almond flour 
• Baking powder
• Sugar free chocolate chips
• 8×8 pan
• Parchment Paper

Now lets combine the simple ingredients to make the brownie dough

Prepare your 8×8 baking dish by lining with parchment paper.

This ensures that you are able to lift your prepared brownies out of the pan once frozen.

Since we are mixing everything up in one bowl, there is no need to mix up the wet ingredients and dry ingredients separately.

Now put your eggs in a small bowl filled with hottest tap water and set aside.

This warms up the egg to room temperature so it does not solidify the fat used in the recipe.

In a medium saucepan over low heat, melt butter and confectioners erithrytol and whisk until well combined.

Watch it as the melted butter takes a bit of whisking to combine with the powdered sweetener.

Once it is whisked in smooth, slowly incorporate the cocoa powder into the butter mixture until smooth.

Remove from heat and let sit 5 minutes to cool a little bit.

Now whisk in the vanilla and eggs one at a time until a very smooth batter is made with a shiny top.

This step is what improves the texture of the brownies to be fudgy.

Now whisk in the almond flour and baking powder until very smooth.

Lastly stir half of the dark chocolate sugar-free chocolate chips. 

It is the secret ingredient that brings out the fudginess of these delicious brownies.

Spread in your parchment lined prepared baking pan.

Sprinkle other half of chips over the top of the unbaked batter or leave them out for less carbs in each serving.

What you will need to freeze your homemade brownies

• Prepared brownie batter
• Parchment Paper
• 8×8 pan (glass or metal)
• Plastic Freezer Bag or AirTight Container

Pour your prepared brownie batter into an 8×8 baking pan that has been lined with parchment paper with an overhang for lifting later.

Now for the best results place in your freezer for 2 hours minimum, overnight is the best option to ensure the freezing process is complete.

Once your brownie batter freezes, gently lift the frozen batter out of the baking tray by lifting up by the sides of the parchment paper.

Set the baking pan aside and fold the edges of the parchment paper in to cover the top of the brownie.

This helps prevent freezer burn. 

You could also cover the surface of the brownie batter with plastic wrap ensuring it touches the batter directly to minimize air exposure.

Now place the frozen brownie batter slab into a Ziploc bag or freezer-safe bag and press out as much air as possible to prevent freezer burn.

Airtight freezer bags make a world of difference in your brownies staying fresh in the freezer.

The shelf life of your frozen brownie batter is up to 3 months for best taste.

You can technically store it long term 8 months if double wrapped with plastic and it does not get freezer burnt.

To thaw or not to thaw? 

Now when you have a chocolate craving and you want a fresh batch of brownies, you can bake your frozen brownie batter. 

You wonder, “Can you bake the brownie batter from frozen?” Yes, good news is that you can!

This is the best part about freezing your brownie batter to be prepared for when you want brownies.

Just put the frozen batter into the original pan you froze it in.

If it is a glass baking pan, you must thaw it first for a little bit so the frozen batter doesn’t crack the glass.

Turn your oven to 350F and let your frozen batter sit at room temperature as the oven preheats.

Bake your frozen brownie batter for the recommended 20 minutes.

You may need to bake for a longer period than that as it is essentially thawing while baking.

Once they are baked and toothpick tests with a few crumbs, let it cool on a wire rack for 10 minutes before lifting out and cutting on a flat surface.

If you do plan ahead and want to thaw the batter before baking, place a paper towel over the top of the frozen batter to absorb any extra moisture that may collect.

Bake as directed in your recipe then enjoy!

Tips, Substitutions, and FAQs

• Consider freezing in portions for convenience. Ice cube trays, muffin tins, or small containers work well for individual brownies.

• Use a Disposable Brownie Pan if you want instead of a baking pan and parchment. This will give you a whole slab of brownie batter or make a larger batch for a full tray of brownies using disposable brownie pans. These can then be easily wrapped in aluminum foil and plastic wrap for storage with the pan and all. This is a great thing if you only have one baking pan to use for brownies, then you can prepare and freeze multiples at once.

• You can freeze any type of brownie batter even an unbaked brownie mix that has been prepared. 

• Watch the cooking time as the initial time will need to be increased by 5-10 minutes.

• If you have a favorite cookie recipe like my Keto Pudding Chocolate Chip Cookies, you can freeze the cookie dough just the same! You will want to let the cookie dough to be frozen in balls on a baking sheet. Then once frozen you will store in a freezer bag. To bake cookies, just let them sit on your baking sheet for 10 minutes before baking as normal.

• I use baking powder instead of baking soda as it holds up to the freezing better with mixed batter and more stable once thawed.

• If you are preparing multiple batches of regular brownies and freezing the batter for later use, make sure you stack in a single layer while they freeze. Once frozen, they can be stacked for storage purposes which is the easiest way to get prepared for the baking season ahead of time!

• There are many different ways you can enhance your brownie batter before you freeze it to have variety later. One way is to stir in your favorite additions like some chopped Keto 3 Musketeers Bars!

—Should I freeze brownie batter in a whole pan or smaller portions?

It’s a good idea to freeze it in smaller portions if you plan to bake individual brownies later. I prefer to make a full recipe as it is a small 8×8 pan. 

—Are you sure that I can freeze brownie batter with raw eggs?

Yes, it’s safe to freeze brownie batter with raw eggs. The concern with food safety comes when you are consuming the raw batter before it is baked. Make sure you only eat baked brownies.

—Can I freeze unbaked cake batter similarly?

Yes, the same principles apply to freezing unbaked cake batter. Unbaked cake batter freezes very similarly. I would put the batter in a pan lined with parchment paper and freeze the same way. You can also bake the cake just as we did the brownie recipe.

—Can I freeze brownie batter with cream cheese or peanut butter?

Yes, you can freeze brownie batter with cream cheese or peanut butter, but it may affect the texture slightly. My modifications on my Low Carb Brownie Recipe to include a peanut butter swirl or cream cheese swirl may separate once thawed.

—How do I prevent freezer burn on the batter’s surface?

Use plastic wrap or parchment paper directly on the batter’s surface to minimize air exposure. Make sure you press out any excess air from the bag before putting it away in the freezer for long term storage.

—What’s the best way to thaw frozen brownie batter?

Thaw it in the refrigerator for a few hours or on the counter for quicker results. I let mine thaw in the baking pan on the counter while the oven is preheating. This way when it goes into your preheated oven it has thawed a little.

—Can I freeze a whole slab of brownies?

Yes, you can freeze an uncut slab of brownies in a disposable pan, wrapped in aluminum foil and plastic wrap. This would work with a larger batch in a 9×13 pan or an 11×15 baking sheet. The same directions apply wether small or large.

—Does the leavening agent stand up to the freezing process?

Yes, this is why I used baking powder in my recipe as it stands up to freezing. Even a boxed brownie mix can stand up to freezing once it is mixed into batter. You will just increase the baking time a few minutes to ensure the middle gets cooked through.
