Torched Banana Brûlée Custard Tart with Dark Rum Caramel

This torched banana brûlée custard tart is the dessert that turns a simple banana into a crackling, caramelized showstopper. A creamy roasted banana custard, spiked with dark rum, bakes inside a crisp sweet tart shell.

Then ripe banana slices are arranged on top and dusted with turbinado sugar, which gets torched until it forms a glassy, amber crust. The contrast of the crunchy sugar, silky custard, and buttery pastry is pure magic.

Banana desserts often play it safe—breads, puddings, and cakes. This tart takes a different path. It borrows the technique of crème brûlée and applies it to a rich, roasted banana custard. The custard is made by whisking roasted banana puree with egg yolks, heavy cream, brown sugar, and aged dark rum, then baking it in a pre-baked sweet tart shell.

Once cool, the tart is topped with fresh banana slices and a generous layer of turbinado sugar, which is torched until it caramelizes into a brittle, crackling crust. The result is a dessert that's creamy, crunchy, boozy, and deeply banana-forward. It's a dessert that feels special but doesn't require a pastry degree to pull off.

Ingredients

Why this recipe works

Roasting the bananas before pureeing them concentrates their natural sugars and deepens their flavor, giving the custard a rich, almost caramel-like banana taste that you don't get from raw fruit. The heavy cream and egg yolks add richness and help the custard set into a velvety, smooth texture that holds its shape when sliced. The dark rum adds a warm, aromatic note that complements the banana without overpowering it.

Baking the custard in a pre-baked tart shell ensures that the pastry stays crisp and doesn't become soggy. The gentle oven temperature of 330°F (165°C) allows the custard to set slowly and evenly, preventing curdling and keeping the texture silky. The final torching of turbinado sugar creates a hard, glassy crust that contrasts with the soft custard and bananas, adding a textural element that makes every bite exciting.

Notes and substitutions

For the tart shell, use a store-bought sweet tart shell or make your own with a standard pâte sucrée recipe. The shell should be fully baked and cooled before filling. If using a homemade shell, blind-bake it with pie weights to prevent it from puffing up.

The custard can be made with fresh or frozen roasted banana puree; if using fresh, roast the bananas at 400°F (200°C) for about 20 minutes until soft and caramelized, then mash or blend until smooth.

Aged dark rum gives the custard a deep, complex flavor, but any dark rum or even bourbon will work. If you prefer to skip the alcohol, substitute with a teaspoon of rum extract mixed with two tablespoons of water, or simply omit it and add a little vanilla extract.

For the topping, turbinado sugar (or Demerara) is ideal because its large crystals melt evenly and create a thick, crunchy crust. Use a kitchen torch for the best control, but a broiler can work if you watch it closely.

• aged dark rum: 1 teaspoon rum extract plus 2 tablespoons water, or omit and add 1/2 teaspoon vanilla extract
• roasted banana puree: Mash 2 very ripe bananas (about 1 cup) and simmer in a pan until thick, or use thawed frozen banana puree
• turbinado sugar: Demerara sugar or coarse granulated sugar
• brown sugar: Coconut sugar or dark muscovado sugar
