This bananas foster bread takes everything I love about the classic dessert and transforms it into the most intensely banana-flavoured banana bread you’ll ever taste. Caramelised bananas in brown sugar and rum get folded into a moist, tender loaf, then served with whipped bananas foster butter that’s ridiculously delicious.

banana foster bread with banana foster butter

I adore bananas foster more than words can say, so it made total sense to carry this flavour profile into banana bread. What’s not to like about brown sugar caramelised bananas in buttery rum?

I searched the internet high and low for the perfect banana bread recipe and found a plethora claiming to be the best ever. In the end, I settled on my favourite banana bread recipe because better the devil you know. I added an extra banana to make it even more banana-forward, and next time I might push it further with two or three more. Sometimes you have to live on the edge.

I’m not typically a fan of adding cinnamon to my banana bread, although I once made it with chocolate and blueberries, which was quite nice. I just can never seem to make my banana bread banana enough. Until now.

Why This Recipe Works

Caramelising the bananas in butter and brown sugar before adding them to the batter creates layers of flavour you simply can’t achieve with raw mashed bananas. The sugars caramelise, the bananas become jammy and concentrated, and the rum adds depth and complexity.

The flambéing step burns off the harsh alcohol whilst leaving behind the deep, rich flavour of the rum. Dark spiced rum works beautifully here, adding warmth and complementing the brown sugar perfectly.

Using five bananas instead of the typical three creates an incredibly moist, dense crumb that’s bursting with banana flavour. This isn’t a light, fluffy banana bread. It’s rich, indulgent and unapologetically banana-forward.

The Bananas Foster Butter

This whipped butter might be my proudest invention. With two very limp, sad, thawed frozen bananas remaining, I decided to foster them up and see if I could make a whipped butter. It worked brilliantly.

The method is identical to making bananas foster for the bread, but you cool the caramelised banana mixture completely, then whip it with softened butter until smooth and spreadable. The result is a decadent, sweet butter that takes this banana bread completely over the top.

Even if you stick with your favourite banana bread recipe, I highly recommend making this bananas foster butter to spread on it.

Frequently Asked Questions For Bananas Foster Bread

Can I skip the flambéing step?
You can, but the flavour won’t be quite as good. Flambéing burns off the harsh alcohol whilst concentrating the rum’s flavour. If you’re nervous about flames, you can skip it, but simmer the rum with the bananas for an extra 2-3 minutes to evaporate some of the alcohol.

Can I make this without alcohol?
Yes. Replace the rum with 1 teaspoon of rum extract mixed with 2 tablespoons of water. The flavour will be different but still delicious. You could also use 2 tablespoons of bourbon or brandy.

What if I don’t have frozen bananas?
Fresh overripe bananas work perfectly. Use the ripest, spottiest bananas you can find. The blacker the skin, the sweeter and more flavourful they’ll be.

Can I add nuts or chocolate?
Absolutely. Fold in 100 grams of chopped walnuts or pecans, or 150 grams of chocolate chips after mixing the batter. Just be aware this will change the texture slightly.

Why is my banana bread dense?
This recipe is meant to be quite dense and moist due to the high banana content. If it’s overly dense, you may have overmixed the batter or your baking powder might be old. Mix just until combined and check your baking powder is fresh.

Can I make muffins instead?
Yes. Divide the batter among 12 muffin cases and bake at 180°C for 20-25 minutes, until golden and springy to the touch.

Do I have to make the butter?
No, the bread is delicious on its own with regular butter. But the bananas foster butter is truly special and takes it to another level.

Tips for Success

Freezing Bananas: I had been very clever and frozen a whole lot of bananas that were about to turn, so I had them right on hand in perfect gooey condition for banana bread. This is one of the best tips I picked up on the internet. They lose a fair amount of liquid as they thaw, but when you peel the black skin off, out pops what looks like a baked banana that’s perfect for baking or butter.

Sugar Choice: I love muscovado or demerara sugar here. It adds to the caramel profile beautifully. You could use any brown sugar, but the molasses-rich varieties give deeper flavour.

Rum Selection: It’s important to flambé the rum to burn the harsh alcohol off, leaving behind the delicious deep flavour. I love to use Captain Morgan Spiced Rum in dessert baking as it imparts great taste. White rum would be a waste of time here. Use a dark or spiced rum for the best results.

Preventing Over-Browning: Line your loaf tin with baking paper. This helps prevent over-browning of the outer part of the loaf, which can happen when baking for a long period. I also loosely cover with foil from about 35 minutes into the baking time to protect the top.

Testing for Doneness: The bread should be golden brown and springy to the touch. Insert a sharp knife into the thickest part of the loaf and ensure it comes out clean. Baking time varies depending on your tin size, so start checking at 70 minutes.

Making Extra Banana: Next time I make this, I’m going to see how far I can take the banana addition and add another two or maybe three. If you’re a serious banana lover, feel free to experiment.

Serving Suggestions for Bananas Foster Bread

Classic: Slice whilst still slightly warm and slather with the bananas foster butter.

Toasted: Toast slices and spread with the butter for an even more caramelised flavour.

With ice cream: Serve a thick slice with vanilla ice cream and an extra drizzle of the butter.

For breakfast: Toast and spread with cream cheese, then add a dollop of the bananas foster butter.

Gift-giving: This makes a stunning gift. Wrap the loaf in cellophane and tie with ribbon, then include a small jar of the butter alongside.

Ingredients

For the bananas foster bread:

150 grams 3/4 cup brown sugar, divided into 50 grams and 100 grams
100 grams salted butter
2 tablespoons dark spiced rum such as Captain Morgan
2 large free-range eggs
1 teaspoon vanilla extract
5 ripe bananas mashed (about 600 grams)
220 grams 1 3/4 cups plain flour
3 teaspoons baking powder

For the bananas foster butter:

30 grams 3 tablespoons butter
2 tablespoons brown sugar
2 mashed bananas about 240 grams
2 tablespoons dark spiced rum
80-100 grams 1/3 cup salted butter, at room temperature

Instructions

Make the Bananas Foster Bread:

Preheat the oven to 180°C/350°F. Line a loaf tin (approximately 23 x 13cm) with baking paper, ensuring the paper comes up the sides.
Melt 100 grams butter in a large frying pan over medium heat. Add 50 grams brown sugar and stir until dissolved. Allow to bubble for 1-2 minutes.
Add the 5 mashed bananas to the pan and cook, stirring, until golden brown and caramelised, about 5-7 minutes. Everything should be molten and caramelly.
Add 2 tablespoons rum to the pan. Carefully ignite with a long lighter or match to flambé. This will burn the alcohol off. The flames will subside after 10-20 seconds. Set aside to cool to room temperature.
In a large bowl with an electric mixer, cream the remaining 100 grams sugar with the 2 eggs until pale, fluffy and doubled in volume, about 4 minutes. Add the vanilla extract and mix briefly.
Add the cooled banana mixture and stir by hand to combine.
Sift the flour and baking powder into the bowl. Using a spatula or wooden spoon, fold gently into the batter until just combined. Do not overmix.
Pour the batter into the prepared loaf tin and smooth the top.
Bake for 35 minutes, then loosely cover the top with foil to prevent over-browning. Continue baking for another 35-45 minutes (70-80 minutes total) until golden brown, springy to the touch, and a knife inserted into the thickest part comes out clean.
Allow to cool in the tin for 10 minutes, then lift out using the baking paper and cool completely on a wire rack.

Make the Bananas Foster Butter:

Melt 30 grams butter in a frying pan over medium heat. Add 2 tablespoons brown sugar and stir until dissolved and bubbling.
Add the 2 mashed bananas and cook, stirring, until golden brown and the sugar is completely incorporated, about 5 minutes.
Add 2 tablespoons rum and carefully flambé as before. Continue cooking for another minute until everything is well combined and caramelised.
Transfer to a bowl and refrigerate until completely cool, about 1 hour.
Once cool, use an electric mixer to whip the banana mixture until smooth. Gradually add 80-100 grams of room temperature butter, whipping until you have a smooth, spreadable consistency. Taste and adjust the butter quantity to your preference.
Serve the banana bread sliced, with generous amounts of the bananas foster butter.

Notes

Use the ripest bananas you can find. Frozen bananas that have been thawed work brilliantly and are actually sweeter.
Dark or spiced rum is essential for the best flavour. White rum doesn’t have enough depth.
Muscovado or demerara sugar adds the best caramel flavour, but any brown sugar works.
The bread is quite dense and moist due to the high banana content. This is intentional.
Lining the tin with baking paper prevents over-browning during the long baking time.
If you’re nervous about flambéing, you can skip it and just simmer the rum for an extra few minutes, though the flavour won’t be quite as deep.
The banana foster butter quantities aren’t exact. Adjust the butter to taste for your preferred consistency.
