Brown Butter Banana Bread

This Brown Butter Banana Bread is soft, moist, and packed with rich banana flavour and warm caramel notes from browned butter. Whipped eggs give the loaf a light, cake-like crumb while still keeping that classic cozy banana bread texture. Easy to make in one bowl with or without a mixer!

I’ve shared a lot of banana bread on the blog already but this banana bread made with brown butter has to be the one we make the most.

All About This Brown Butter Banana Bread

This brown butter banana bread is an adaption of my mom’s banana bread recipe that she’s been making since before I was even born. If you’ve ever had classic North American-style banana bread, it’s usually dense, very moist, hearty, and on the sweeter side. Japanese-style banana bread on the other hand tends to be lighter, fluffier, less sweet, and airy from whipped eggs incorporated into the batter.

I love both styles, so I wanted to combine everything I love about each into one loaf and this is it. This banana bread:

• bakes up tall and golden
• stays ultra soft and moist without feeling gummy
• has a tight plush crumb that still feels light
• gets deeply caramelized edges
• isn’t overly sweet
• has rich banana flavour with caramel-nutty notes from browned butter

And although I use a stand mixer for this recipe, you can easily make it in one bowl by hand and it’ll still turn out delicious.

Ingredients and Substitutions

This brown butter banana bread uses simple pantry ingredients, but each ingredient plays a role in creating a loaf that’s soft, moist, flavourful, and light without feeling overly heavy. Here are the main ingredients you’ll need:

• Salted butter: Browning the butter gives the banana bread a deeper caramelized, nutty flavour that makes it taste richer and more bakery-style. I prefer salted butter here because it balances the sweetness and enhances the banana flavour.
• Neutral oil or refined coconut oil: A small amount of oil helps keep the loaf soft and moist for days, even after the browned butter firms up as it cools. Use any neutral oil you like.
• Eggs: Whipping the eggs with sugar helps aerate the batter, creating a lighter, softer crumb that’s inspired by Japanese-style banana bread. Room temperature eggs whip up with more volume, but cold eggs will still work.
• Sugar: I like using a mix of brown sugar and white sugar. Brown sugar adds moisture and a slight caramel flavour while white sugar keeps the crumb lighter. You can adjust the sugar depending on how sweet you like your banana bread.
• Mascarpone, crème fraîche, or sour cream: Adds richness and keeps the crumb extra tender and moist. Mascarpone gives the richest flavour, while sour cream adds a slight tang. You can even use full fat greek yogurt or heavy cream in a pinch.
• Ripe bananas: The best bananas for banana bread are heavily spotted and very sweet, but not completely black and watery. Overly mushy bananas can make the loaf too dense or gummy.
• Toasted milk powder (optional): Adds extra nutty, almost butterscotch-like flavour that pairs really well with the browned butter. It’s optional, but highly recommended if you have it.
• Cinnamon, nutmeg, vanilla extract and salt: Adds warmth without overpowering the banana flavour.
• Baking Powder and Baking soda: Reacts with the bananas and dairy to help the loaf rise while also contributing to browning and caramelization.
• All-purpose flour: Keeps the banana bread soft and tender while still giving enough structure to support the very moist batter.

How to Make Brown Butter Banana Bread

This brown butter banana bread comes together with a few simple techniques that give it a soft, plush crumb and rich caramelized flavour. Here’s an overview of how to make it:

1. Brown the butter: Cook the butter until the milk solids turn golden brown and smell nutty. You can read more about brown butter in my How to Brown Butter post.
2. Toast milk powder: Heat the milk powder until deeply golden brown.
3. Whip the eggs and sugar: Beat until pale, thick, and airy to create a lighter banana bread texture.
4. Add in brown butter: Drizzle the browned butter down along the sides of the bowl to slowly incorporate it into the whipped eggs.
5. Add remaining wet ingredients: Mix in the mascarpone, vanilla, bananas, spices ad leavening agents until bananas are mostly mashed up.
6. Add the dry ingredients: Stir in the flour and mix-ins until just combined.
7. Bake: Pour into a loaf pan and bake until tall, golden brown, and a skewer comes out mostly clean with a few moist crumbs.
8. Cool: Let the loaf cool before slicing so the crumb can fully set.

How to Determine if Brown Butter Banana Bread is Done Baking

Because banana bread has such a moist batter, it can sometimes look done on the outside while still being underbaked in the center. The best way to check is by inserting a skewer or toothpick into the middle of the loaf. You’re looking for a few moist crumbs, but no wet batter. The top should also feel set and spring back lightly when gently pressed. If the loaf is browning too quickly before the center is done, loosely tent the top with foil for the remaining bake time.

Another good indicator is the smell and appearance. Properly baked banana bread will have deeply golden edges, a domed top with cracks, and a rich buttery banana aroma. Keep in mind that banana bread continues to cook slightly as it cools in the pan, so it’s better to slightly underbake than overbake if you want a softer, moister crumb.

Moistness of Banana Bread

A really good banana bread isn’t just about adding more bananas. Moistness comes from the balance of fat, liquid, and structure in the batter. Oil-based cakes are usually softer and moister because oil stays liquid at room temperature, while butter firms up as it cools. But butter gives a richer flavour, especially once browned, which is why this recipe uses both.

The browned butter adds deep caramelized flavour while a small amount of oil and mascarpone help keep the loaf soft and plush for days. As I mentioned earlier, the bananas matter too! Heavily spotted bananas give the best balance of sweetness and moisture, while overly black and watery bananas can sometimes make banana bread too dense or gummy.

Serving Suggestions

This banana bread is soft and moist enough to eat on its own, but I love serving it with an extra swipe of salted butter. It’s also really good warmed up with whipped cream or a scoop of vanilla ice cream for more of a dessert moment.

One of my favourite ways to eat it though is frying thick slices in a little more butter until the edges get golden and crisp. It makes the banana bread even toastier, richer, and extra buttery.

How to Store and Reheat Leftovers

This brown butter banana bread stays soft and moist for several days thanks to the bananas, oil, and mascarpone in the batter. Once completely cooled, store the loaf tightly wrapped or in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to 1 week or freeze individual slices for up to 2 months.

To reheat, microwave a slice for 10–15 seconds or warm it in a toaster oven until soft and lightly toasted. I especially love frying slices in a little butter until the edges get golden and crisp.
