Most quick breads and loaf cakes depend on baking soda to rise, but here's a recipe for banana bread without baking soda, that relies on baking powder.
Baking soda versus baking powder in banana bread
Old-school banana bread recipes are usually made with baking soda only and without baking powder. I gather that there was a time when baking powder wasn't as readily available, but also that the consistency of baking powder sold in grocery stores varied. Baking powder wasn't the reliable chemical leavener it is today.
Remember that baking soda is sodium bicarbonate and requires acidic ingredients to react to form carbon dioxide. The acidity in banana bread could come from the mashed bananas, which have a pH that is between 4 and 5.
Baking powder is made from sodium bicarbonate, acid(s), and a drying agent (or anti-caking agent) like cornstarch. It's a complete leavening agent and all you have to do is wet it and apply a little heat to make it react.
What does baking soda do in banana bread?
In banana bread, baking soda does more than just help the loaf cake rise:
- it increases the pH of the batter, leading to a browner, much darker crumb and crust
- it tenderizes by reducing gluten formation in the batter
- it adds flavour, especially since most banana bread recipes call for 5 mL (1 teaspoon) or more of baking soda, which is quite a lot for such a small quantity of flour and batter.
Examples of quick breads with baking soda
This eggless banana bread is made with baking soda only, as is this healthier pumpkin bread. And when I was working on this pumpkin bread, I found that I had no choice but to use both baking powder and baking soda, though I tried really hard to eliminate the baking soda. The pumpkin loaf cake required both leavening agents to rise properly and achieve the perfect texture.
Why bake banana bread without baking soda
I find baking soda, especially in some loaf cake recipes and quick breads, can provide too much flavour. While some tasters don't notice it, I find I'm particularly sensitive to it, and the flavour in some instances can verge on soapy.
Baking Soda Substitute In Banana Bread
Though in some recipes, it's inevitable, I prefer the taste of banana bread without baking soda, which has a milder more buttery flavour and a lighter, golden brown colour with a pale yellow crumb inside. Baking powder is a good substitute for baking soda in banana bread. A good rule of thumb is to use at least 5 mL (1 teaspoon) of baking powder for every cup of flour.
And though I couldn't get the pumpkin bread to work without baking soda, I am happy to report that banana bread without baking soda does work beautifully, with the recipe below.
📖 Recipe
Banana Bread Without Baking Soda
Ingredients
- 250 grams bleached all-purpose flour
- 10 mL baking powder
- 5 mL Diamond Crystal fine kosher salt
- 175 grams unsalted butter softened
- 200 grams granulated sugar or a mix of brown sugar and granulated sugar
- 2 large egg(s) room temperature
- 5 mL pure vanilla extract
- 330 grams mashed banana roughly 3 ripe bananas, approximately 450 grams with peel
Instructions
- Preheat the oven to 350 ºF (175 °C). Butter and flour an 8½ x4½-inch (21.5x11.5 cm) loaf pan OR a 9x5-inch (23x12.5 cm) loaf pan, then line the bottom with a rectangle of parchment paper. Set aside.
- In a medium bowl, whisk together the flour, baking powder, and salt.
- In a large bowl, using an electric hand mixer, cream together the butter and sugar for at least 5 minutes until light and fluffy. Be sure to scrape down the sides of the bowl often to make sure the mixture is evenly whipped.
- Add the eggs, one at a time, mixing in between each addition. Mix in the vanilla, if using.
- Add the mashed banana. Mix well, scraping the bottom and sides to incorporate everything.
- Dump in the flour and fold it in with your spatula.
- Pour the batter into the prepared loaf cake pan. Smooth the top to even it out.
- Bake for 60–65 minutes for a 9x5" loaf or up to 75 minutes for an 8.5"x4.5" pan, until the edges are a deep golden brown and a cake tester inserted into the middle comes out clean.
Notes
- Use the largest bananas you can find for this recipe: I used a pound of bananas and after peeling, I was left with roughly 330 grams of fruit, which works out to 330 mL (1⅓ cups) but this recipe can accommodate up to 375 mL (1½ cups) of mashed banana. Don't use more than that.
- Make sure the bananas are very ripe (black even).
- If you are using frozen bananas for this recipe, please make sure do the following:
- defrost the bananas
- peel the bananas and place in a strainer set over a bowl
- press very gently to squeeze out the liquid
- either discard the banana liquid OR place the liquid in a saucepan and boil it down to a couple tablespoons, stirring often so that it doesn't burn. Add this banana concentrate to the bananas and proceed with recipe.
- If you want to make a fancier banana bread, add any of the following:
- add 250 mL (1 cup) chocolate chips
- add 250 mL (1 cup) chopped walnuts or chopped pecans
- add 5 mL (1 tsp) ground cinnamon
- add 10 mL (2 tsp) ground cardamom
- add 5 mL (1 tsp) vanilla extract
- You can also use a thermometer to check if your cake is done baking and the internal temperature should register around 212 ºF or 100 ºC when it's done.
- If you don't have eggs or are allergic, try this eggless banana bread recipe.

Frequently asked questions
If your loaf cake is dense, it could be that your ratio of wet ingredients to dry ingredients was off. Did you measure the bananas before adding them to the batter? Often people add too much banana, leading to a dense banana bread.
You may need to add more leavening agent if you want to try to add more banana to this recipe, but I don't recommend adding more than 375 mL (1.5 cups) of mashed banana with this recipe.
Make sure to check if your cake is done with a cake tester and a thermometer (internal temperature around 212 ºF or 100 ºC when baked). If there's a gummy layer at the bottom of the banana bread, it could be that your ratio of wet to dry ingredients was off. Did you add extra banana? Or did you defrost your bananas to make the cake? If so, the mashed banana will end up very wet, and I recommend straining the liquid and cooking it down to evaporate some of the water before mixing it into the batter.

I made it, and my mom said that it was better than anything that she ever made.

Can I use this recipe with a muffin pan?? I can't seem to find my loaf pan
Janice says
Hi Tea, I think this recipe will work great in muffin pans! I think it will make about 12 muffins and the baking time will be reduced, start checking them after 20 minutes, but I suspect they may take 25 minutes even. Let me know how it goes!

This was delicious!

So nice absolutely love this recipe

Hi, is this a mistake, you say;
Bake for 60–65 minutes for a 9x5" loaf or up to 75 minutes for an 8.5"x4.5" pan.
Shouldn’t it be the shorter time for the smaller loaf, not longer?
Thanks
Janice says
Hi, Thanks for your comment. I find taller cakes tend to take longer to bake. In this case, in the smaller pan, the batter fills more of the pan, which is more narrow. As always, I highly recommend using a few different techniques for checking if the cake is done baking, rather than the oven timer. I hope that makes sense and if you can, drop by once you've baked the cake to let us know how long it took in your cake pan! Happy baking!
Fen says
I’m sorry, so the times are actually correct?
Thanks
Janice says
Hi! Yes! But really, always use a cake tester to double check. Your oven and the material of your pan will have an impact on baking time. The baking times are just a suggestion based on my tests 😉
Hope that is clear! Happy baking!

Thanks for the additional feedback Janice, really appreciated!

I made this recipe using dark chocolate chips and pecans and used 1/2 white sugar and 1/2 brown sugar which gave them kind of a caramelized crunch to them ! Also put in the cinnamon and vanilla and they were the BEST !! Great recipe and would definitely make again ! Thank You

This recipe worked great! I was able to make some delicious banana bread 🙂
