Equipment
-
10-inch ovenproof skillet (cast iron is ideal) or 8×8 baking dish
-
Medium mixing bowl
-
Whisk
-
Pastry cutter or forks (or clean fingers)
-
Rubber spatula
-
Measuring cups and spoons
Instructions
Step 1: Prep & Make the Crumble (Time: 10 minutes | Intensity: Low)
-
Preheat Oven: Preheat your oven to 375°F (190°C).
-
Mix Dry Ingredients: In a medium bowl, whisk together the rolled oats, flour, brown sugar, cinnamon, and sea salt.
-
Cut in Butter: Add the cold, cubed butter. Using a pastry cutter, two forks, or your fingertips, work the butter into the dry mixture until it resembles coarse, wet sand with pebble-sized clumps. These clumps will become your delicious, crunchy topping.
-
Add Chocolate: Gently stir in the dark chocolate chips. Place the bowl in the refrigerator to keep the butter cold while you cook the bananas.
Pro-Tip: Cold butter is the secret to a crunchy, non-greasy crumble. It creates steam pockets as it bakes, leading to perfect texture.
Step 2: Caramelize the Bananas (Time: 10 minutes | Intensity: Medium)
-
Melt & Sugar: In your ovenproof skillet over medium heat, melt the 3 tablespoons of butter. Sprinkle the ⅓ cup brown sugar evenly over the melted butter. Let it cook, without stirring, for 1-2 minutes until it begins to bubble and melt into the butter.
-
Create the Sauce: Whisk in the heavy cream and sea salt. Let it simmer for 1 minute, whisking constantly, until it forms a smooth, cohesive caramel sauce.
-
Cook Bananas: Remove the pan from the heat. Carefully arrange the banana slices in a single, snug layer in the pan, gently pressing them into the sauce. Return the pan to medium-low heat and cook for 3-4 minutes, without moving them, to allow the bottoms to caramelize.
-
Finish & Flambé (Optional): Remove from heat again. Pour the vanilla and rum (if using) over the bananas. If you’re feeling dramatic and your kitchen is safe, you can carefully ignite the alcohol with a long lighter to flambé, letting the flames die down on their own. If not, simply stir gently—the alcohol will cook off in the oven.
Intensity Note: This step requires attention. The sugar can go from caramelized to burnt quickly. Keep the heat at medium and watch it closely.
Step 3: Assemble & Bake (Time: 20 minutes | Intensity: Low)
-
Top with Crumble: Remove the crumble mixture from the fridge. Sprinkle it evenly over the entire surface of the caramelized bananas and sauce, covering them completely.
-
Bake: Transfer the skillet to the preheated oven. Bake for 18-22 minutes, until the crumble topping is golden brown, the chocolate chips are melty, and the sauce is bubbling vigorously around the edges.
-
Rest: Remove from the oven and let it cool for 5-7 minutes. This allows the molten caramel sauce to settle slightly, preventing burnt tongues and perfecting the texture.
Step 4: The Grand Finale – Serve (Time: 2 minutes | Intensity: Low)
-
Scoop & Serve: Spoon the warm crumble directly from the skillet into shallow bowls. The layers should be glorious: crispy topping, soft bananas, rich sauce.
-
The Essential Finish: Immediately top each serving with a generous scoop of cold vanilla ice cream. The hot/cold contrast is the soul of this dessert.
-
Garnish: Finish with a delicate pinch of flaky sea salt over the ice cream. This heightens every flavor—chocolate, caramel, banana.

The Last Bite: A Masterclass in Flavor & Technique
Why This Dessert Wins:
This isn’t just another banana dessert. It’s engineered for maximum sensory pleasure. The caramelization of the bananas in a buttery sauce deepens their flavor beyond mere sweetness. The crumble provides essential crunch and a bitter note from the dark chocolate that balances the sugar. The cold ice cream melts into the warm sauce, creating a DIY creamy banana split experience in every bite. The flaky salt is the conductor, making all the individual flavors sing louder.
Storage & Reheating (For Rare Leftovers):
-
Refrigerator: Store any cooled leftovers in an airtight container in the refrigerator for up to 2 days.
-
Reheating: Reheat single portions in a microwave for 30-45 seconds until warm, or in a 350°F (175°C) oven for 10 minutes to re-crisp the topping. Always re-top with fresh cold ice cream.
Chef’s Notes & Ingenious Variations:
-
The Banana Rule: Use bananas that are yellow with brown speckles (ripe). Green bananas lack sweetness; overripe black bananas will turn to mush. Their structure is key.
-
Skillet vs. Dish: A cast-iron skillet is perfect because it goes from stovetop to oven and retains heat beautifully for serving. A baking dish works too—just cook the bananas in a separate pan and transfer them with the sauce to the dish before topping and baking.
-
Chocolate Choice: A dark chocolate bar (60-70%), chopped, is superior to chips. It melts more luxuriously and offers a more sophisticated, less sweet flavor.
-
Alcohol-Free: Simply omit the rum. The flavor will still be incredible.
-
Nutty Bliss: Add ¼ cup chopped pecans or walnuts to the crumble mixture.
-
Coffee Kick: Add 1 teaspoon of instant espresso powder to the caramel sauce with the cream for a mocha nuance.
-
Tropical Twist: Add ⅓ cup toasted coconut flakes to the crumble and a tablespoon of lime zest to the caramel sauce.
Troubleshooting:
-
Soupy Sauce: Your bananas may have been overripe, releasing too much water. Simmer the sauce for an extra minute or two before adding the crumble to thicken it.
-
Soggy Topping: You forgot the cold butter! Or you pressed the crumble down into the sauce. Just sprinkle it loosely. Also, ensure your oven is fully preheated.
-
Burnt Sugar: Heat was too high during caramelization. Medium heat is your friend. If it starts to smoke, remove from heat immediately and whisk in the cream to stop the cooking.
This dessert is a celebration of contrasts and a testament to the magic that happens when simple ingredients are treated with a bit of culinary ambition. It promises and delivers pure, unadulterated joy in a bowl. Gather your ingredients, and prepare for applause.
