Can I Use Frozen Bananas in Banana Bread?

Yes, of course! You can freeze all of your ripe bananas to use in baking recipes like banana bread, banana muffins, banana cake, and (my favorite) chocolate banana muffins. If you have spotty, nearly black, heavily ripened bananas on the counter, but don’t have the chance to bake with them right now, go ahead and freeze them to use for your baked goods at a later time.

Time is on your side this way! You’ll always have bananas ready for banana bread if your freezer is stocked. Go ahead and build up a frozen stash. 😉

Freeze Bananas Whole (If Using for Baking)

If I’m freezing bananas to use in smoothies, I usually cut them into chunks first, because my blender can’t really handle whole frozen bananas. You usually do not have to thaw bananas if using them in smoothies, like my favorite pumpkin pie smoothie.

But to use in baking recipes, you need to thaw the frozen bananas first, because you need to mash them for your recipe. Many online tutorials may tell you to leave the peels on when freezing them, and that definitely works! I like to peel the bananas before freezing them. Here’s why:

  • Peeled bananas take up less room in your freezer-friendly container.
  • Peeled bananas thaw a little quicker.

Either way works. I also recommend freezing the bananas whole, and here’s why:

  • Baking recipes usually call for a specific number of bananas, such as “3 large bananas.”
  • Bananas can vary in size, so if you cut them up before freezing, it may be hard to determine how much you need.

Freezing bananas whole helps you determine exactly how much you need so you aren’t defrosting too little or too much.

You can freeze bananas in a large zipped-top freezer bag or any covered container. I like to use these glass freezer containers, which are fantastic for freezer meals & snacks, too.


Freeze Up to 3–6 Months

Freeze bananas for up to 3–6 months. Freezing bananas beyond 6 months may be fine, but the peeled bananas do begin to darken over time, and then they thaw into an overly mushy mess. I’ve found up to 6 months is fine, and under 3 months is even better.


How to Defrost Bananas for Baking

You can use either of these defrosting methods:

  1. Remove the frozen bananas from the freezer and thaw at room temperature for 2 hours, or in the refrigerator overnight.
  2. Defrost in your microwave at 50% power. The time varies depending on your microwave, but for 4–5 bananas, this probably takes around 3 minutes.

After thawing, bananas are slippery, mushy, and sitting in a pool of brown liquid.

#1 Success Tip: Strain the Brown Liquid

When thawing your frozen bananas, they release a pool of brown liquid. Pretty much any tutorial I’ve seen tells you to leave the brown liquid and mash the bananas and liquid together. Here is all the liquid that 5 frozen bananas released when thawing:

I actually strain all of this liquid out and discard it. (Tip: If your banana baked good recipe calls for a liquid (like milk), you could use this brown banana liquid instead.)

Mashing up your thawed bananas with this liquid might work for some recipes, but I’ve found it makes most baked goods overly dense and heavy. That’s because your mashed banana mixture is thinner, almost liquid-y instead of being chunky. In this banana bread, for example, you’re now adding 2 cups of a thin liquid instead of 2 cups of a chunky add-in. And there’s not enough dry ingredients in the batter to support that extra moisture.

The following photo shows 2 slices of banana bread:

  1. The left slice is from a loaf made with frozen, thawed, and mashed bananas with nearly all of the excess liquid strained off. This loaf rose nicely and was soft, moist, and tender as intended.
  2. The right slice is from a loaf made with frozen, thawed, and mashed bananas with the defrosted brown liquid. Even though this is the natural moisture from the thawed bananas, it produced an overly thin mashed banana mixture and therefore weighed down the banana bread. This loaf took much longer to bake, had a chewier exterior, tasted overly dense, and was quite squat.

You will notice a difference if you mash your thawed bananas with the excess liquid and that difference may not be desirable. Again, if your recipe calls for a liquid such as milk, you can replace some of it with the banana liquid. This banana cake, for example, uses 1 and 1/2 cups (360ml) buttermilk. You may get 1/4 cup (60ml) brown liquid from your 3 frozen and thawed bananas, so go ahead and replace 1/4 cup (60ml) of buttermilk with the banana liquid.

Here are 3 frozen, thawed, and mashed bananas with pretty much all of the brown banana liquid strained off. The mixture is chunky and pretty thick, which is how it looks if using regular ripe bananas that have not been frozen. (Which is what we’re trying to replicate.)

This isn’t really a “recipe” but I figured putting it all in a printable recipe card would be most helpful. Do you freeze bananas to use in baking?

Description

Use this simple guide to freeze and thaw your ripe bananas for baking recipes. You can peel the bananas or leave the peel on, it doesn’t make a difference either way. If leaving the peel on, the peels considerably darken in the freezer.


Ingredients

  • 4 ripe bananas (or however many you have)
  • freezer container


Instructions

  1. Place bananas in a freezer container. Feel free to peel first or leave the peel on. You can freeze bananas in a large zipped-top freezer bag or any covered container, such as these glass freezer containers.
  2. Freeze bananas for up to 3 months.
  3. Defrost: Remove the frozen bananas from the freezer and thaw at room temperature for 2 hours, or in the refrigerator overnight. Or you can defrost in your microwave at 50% power. The time varies depending on your microwave, but for 4–5 bananas, this probably takes around 3 minutes.
  4. Bananas release liquid as they thaw. For best success in your baking recipe, pour all or most of this liquid out because it could add too much liquid to your batter. (Tip: If your banana baked good recipe calls for a liquid like milk, you could use this brown banana liquid instead. See recipe Note.)
  5. Gently mash thawed, strained bananas with a fork and then use in your baking recipe, such as banana bread.

Notes

  1. If it’s helpful: 1 very large banana usually gives you about 1/2 cup (115g) of mashed banana. When freezing and thawing the banana, this amount may be a little less since you are discarding some excess liquid. So if a recipe calls for 2 cups of mashed bananas (usually about 4 very large bananas, or 460g), you may need 5 frozen, thawed bananas.
  2. Using the brown banana liquid: If your recipe calls for a liquid such as milk, you can replace some of it with the banana liquid. This banana cake, for example, uses 1 and 1/2 cups (360ml) buttermilk. You may get 1/4 cup (60ml) brown liquid from your 3 frozen and thawed bananas, so go ahead and replace 1/4 cup (60ml) of buttermilk with the banana liquid.
  3. Can I combine frozen, thawed, mashed bananas with bananas that have not been frozen? Yes. If you have ripe bananas on your counter AND frozen bananas in your freezer, you can combine the mashed ripe bananas and the frozen, thawed, strained, mashed bananas to yield however much mashed banana you need in your baking recipe.

    Why doesn’t my banana bread rise? My recipes call for two loaf pans, maybe I should just use one? Otherwise I always have “bread” that is about 2 inches high.

      Hi Ty, If your banana bread did not rise, your baking soda could be old – we would try again with fresh!

      Another thought to consider, what size loaf pans are you using? My recipe that I use calls for large loaf pans (9×5). Perhaps try small loaf pans (8×4)? If your baking soda is older, try adding an extra 1/2-1 teaspoon…

    I’ve been just placing the bananas straight from the counter, right to the freezer. Ooops! Was never taught or told otherwise. Thank you for explaining about the brown water from the thawed bananas. It totally makes sense now why my banana bread was so dense. Ahhhh!

      SAME! I would just toss the banana in the freezer as is, no bsg, no container….and when using. I would just peel the banana and dump it in, juice and all. Now we know! Lol.

    When I make banana bread with frozen bananas this is what I do: Put the flour/sugar mix in a bowl in the oven for 5 minutes so it’s hot, chop up the frozen banana and throw it into the flour/sugar with the eggs and butter, the heated flour quickly thaws the banana while i continue to chop it into smaller pieces, and it’s exactly the same as using unfrozen ripe banana. Having ‘chunky’ banana makes no difference, the chunks disappear when you bake it

    Years ago I received a tip on freezing bananas. Do not peel! Put in a zip bag with skins on. peel when thawed. They do not get dark and nature’s peeling protects the fruit.

    So far I’ve only used frozen bananas to make your Bowl Baked Oatmeal and put in the liquid as well. In that it added a little sweetness and tasted great!
    I’ll make sure to discard the liquid when making cakes and bread. Thanks so much for this explanation.

    When I make banana bread, I thaw the bananas in the oven, still wrapped in foil, I freeze them that way. As the oven is preheating. That way I can measure out ingredients, while they thaw out.
    I use, parchment on the jelly roll pan, as they defrost.
