Imagine tender banana slices caramelised in rich brown sugar, topped with a crunchy oat crumble topping that bakes to golden brown perfection. It's a cosy, old-fashioned dessert that uses simple ingredients and turns them into something truly irresistible.

This comforting pudding takes inspiration from my apple and banana crumble pudding I made years ago - but it's even more gooey and delicious!

It's a great way to use up a bunch of overripe bananas or fresh bananas that need a new purpose - especially if you're tired of banana bread or banana crumb cake.

Once baked, serve warm with a scoop of vanilla ice cream, whipped cream, custard or even a few tablespoons of yogurt for a lighter version. You might also many of our other crumble bakes that the whole family will adore!

🛒 Ingredient Notes

Please see the printable recipe card with exact ingredient quantities and preparation instructions at the bottom of this post.

For the Banana Filling

Butter - use cold butter for best texture, as it melts slowly when caramelising the fruit
Brown sugar - adds depth and sweetness with that irresistible toffee flavour
Plain flour (AP) - to thicken the syrup while baking
Lemon juice - adds a subtle tang that balances the sweetness and deepens the caramel's flavour
Pure vanilla extract - enhances the caramel flavour beautifully
Ground cinnamon - the perfect spice for sweetness and warmth
Salt - balances all the flavours.
Ripe but firm bananas - sliced into thick 1-inch chunks to hold their shape, but don't worry if you have overripe ones - better in this dish than in the bin!

For the Crumble Topping

Old-fashioned rolled oats - gives that signature crunchy oat texture
Plain flour (all purpose flour) - for structure and binding
Light brown sugar & granulated sugar - this combination gives both depth and crispness
Ground cinnamon - adds warmth to the topping
Cold unsalted butter (cut into little pieces) - use cold butter to keep that crumbly texture
Walnuts pieces - adds crunch and nuttiness as it will toast while baking

Optional:
Add a pinch of nutmeg, or a spoon of sour cream to the syrup for richness dark chocolate chunks or other fruits if desired

📋 Instructions

1. Prepare the Bananas:

First, preheat the oven to 180°C / 160°C fan, gas mark 4 or 350°F and lightly butter a medium baking dish or 4-6 ramekins.

In a large bowl, cut the bananas into 1" (2.5cm) chunks toss with 1 tablespoon of flour to lightly coat and set aside.

2. Make the Caramel Syrup:

In a large pan, melt the butter, brown sugar, lemon juice, vanilla, cinnamon, and salt and simmer for 2 minutes until it starts to bubble and form a syrup.

Remove from the heat and carefully stir in the bananas until coated well and transfer the caramelised mixture into your prepared dish and spread in an even layer.

3. Prepare the Crumble Topping:

In a medium bowl (or mixing bowl), combine oats, flour, butter, sugars, and cinnamon.

Add cold butter cubes and rub together using your fingers or a pastry cutter until a crumbly mixture forms. You're aiming for small crumbs and a few larger buttery clumps.

4. Assemble:

Sprinkle the crumble mixture evenly over the banana filling.

Place in the preheated oven and bake for 25 minutes until the top is golden brown and bubbling at the edges.

Allow to cool a little before serving with a scoop of vanilla ice cream, a dollop of whipped cream, or warm custard.

Tip: avoid overboiling the syrup to prevent it from being too thick.

❓ FAQ

Can I use overripe bananas in a banana crisp?

Yes! Overripe bananas add natural sweetness, though fresh bananas will hold their shape better.

Can I make this ahead of time?

Yes, assemble and cover with plastic wrap, then refrigerate and bake later for convenience.

Can I add other fruit?

Absolutely - this crumble bakes beautifully with apples, berries or other fresh fruit.

What if I don't have oats?

You can substitute part of the oats and make a cookie crumble topping like crushed biscuits or breadcrumbs for a unique texture.
