Slow Cooker Bananas Foster or Slow Cooker Caramelized Bananas.
This recipe transforms raw, firm bananas into a buttery, rum-infused, brown sugar syrup that is incredible over ice cream or pound cake. It is essentially a “dump and go” dessert that makes your house smell like a New Orleans bakery.
The 4 Ingredients
-
4-5 Firm Bananas (raw, peeled, and sliced into 1-inch chunks)
-
Use bananas that are yellow with just a hint of green. If they are too ripe, they will turn to complete mush.
-
-
1/2 cup Brown Sugar (packed; light or dark)
-
1/4 cup Butter (salted), melted
-
1/4 cup Rum (or 1 tsp Rum Extract mixed with 1/4 cup apple juice)
-
Dark rum is best for depth, but any rum works.
-
Optional: 1 tsp Cinnamon and 1 tsp Vanilla Extract (these enhance the “bananas foster” vibe).
The Method
1. Prep the Bananas
-
Peel the bananas and slice them into thick coins (about 1-inch thick). If they are very long, you can also slice them in half lengthwise, then cut the halves in half.
2. Combine in the Slow Cooker
-
Place the banana slices into the slow cooker.
-
In a small bowl, whisk together the melted butter, brown sugar, and rum (plus cinnamon/vanilla if using).
-
Pour the mixture over the bananas and gently toss to coat.
3. Cook
-
Cover and cook on LOW for 1.5 to 2 hours.
-
Do not cook on High, and do not leave them for 4 hours—bananas break down fast.
-
Check at 1 hour: They should be soft and swimming in a caramel sauce, but still holding their shape.
4. Serve Immediately
-
Spoon the warm bananas and the thick, syrupy sauce over:
-
Vanilla ice cream
-
Pancakes or waffles
-
Cheesecake
-
Plain yogurt or oatmeal
-

⚠️ The Most Important Tip
Bananas are delicate.
Unlike apples or pears, bananas turn to mush very quickly with heat.
-
Don’t stir them once they start cooking, or you’ll end up with banana soup.
-
Slice them thick. Thin slices will dissolve.
-
Serve immediately. If they sit in the warm slow cooker for an hour after cooking, they will disintegrate.
