Ingredients
- 3 ripe but firm bananas, sliced
- 1 box yellow cake mix, approximately 15.25 ounces
- 1/2 cup unsalted butter, melted
- 3/4 cup packed brown sugar
- 1 teaspoon ground cinnamon
- 2 large eggs
- 1 cup milk
- 1 teaspoon vanilla extract
Optional for serving: vanilla ice cream, whipped cream, or chopped pecans.
Equipment Needed
- 5- to 6-quart slow cooker
- Mixing bowls
- Whisk or electric mixer
- Measuring cups and spoons
- Nonstick cooking spray
Instructions
Step 1: Prepare the Slow Cooker
Lightly coat the inside of a 5- to 6-quart slow cooker with nonstick cooking spray. For easier serving and cleanup, you can also use a slow-cooker liner designed for cooking.
Step 2: Make the Bananas Foster Layer
Arrange the sliced bananas across the bottom of the slow cooker.
In a small bowl, combine the melted butter, brown sugar, and cinnamon. Stir until the mixture is evenly combined, then spoon it over the bananas.
This buttery brown sugar mixture creates the caramel-inspired topping as the dessert cooks.
Step 3: Prepare the Cake Batter
In a large mixing bowl, combine the yellow cake mix, eggs, milk, and vanilla extract.
Whisk until the batter is smooth and no large dry pockets remain. Avoid overmixing, which can make the cake dense.
Step 4: Add the Batter
Carefully pour the cake batter over the banana mixture. Spread it gently into an even layer without stirring it into the bananas and caramel mixture.
Keeping the layers separate helps create a soft cake topping with a sweet banana sauce underneath.
Step 5: Slow Cook the Cake
Cover and cook on HIGH for approximately 2 to 3 hours or on LOW for approximately 3 to 4 hours.
Cooking times vary by slow cooker, so begin checking early. The cake is ready when the center is set, the top looks cooked, and a toothpick inserted into the cake portion comes out without wet batter. The cake portion should reach 200–210°F for a typical fully baked cake.
Avoid lifting the lid frequently because this releases heat and extends the cooking time.
Step 6: Rest and Serve
Turn off the slow cooker and let the cake rest for 10 to 15 minutes before serving.
Spoon portions into bowls, making sure each serving includes both cake and the warm banana topping. Add a scoop of vanilla ice cream or a dollop of whipped cream if desired.
Tips for the Best Slow Cooker Bananas Foster Cake
Choose the right bananas. Use ripe bananas with yellow skins and a few brown spots. Very soft bananas can break down too much during cooking.
Grease the slow cooker well. This helps prevent sticking around the edges and makes serving easier.
Keep the lid closed. Slow cookers rely on retained heat, and repeatedly opening the lid can delay cooking.
Check the center carefully. Slow cookers vary in temperature. If the middle is still wet, continue cooking in 15- to 20-minute increments.
Let the cake rest. A short resting period allows the caramel sauce to settle and makes the cake easier to serve.
Use a serving spoon. This is a soft, spoonable dessert rather than a firm layer cake, so it is best served directly from the slow cooker.
Variations
Bananas Foster Pecan Cake
Add 1/2 cup chopped pecans over the bananas before pouring in the cake batter. The pecans provide a pleasant crunch and complement the caramel flavor.
Chocolate Banana Cake
Use chocolate cake mix instead of yellow cake mix for a chocolate-and-banana combination.
Extra Cinnamon Cake
Increase the cinnamon to 1 1/2 teaspoons and add a small pinch of nutmeg for a warmer, spiced flavor.
Caramel Banana Cake
Drizzle a little caramel sauce over each serving just before serving for an even richer dessert.
Banana Walnut Cake
Replace the pecans with chopped walnuts for a classic banana bread-inspired variation.
What to Serve with Bananas Foster Cake
This cake is delicious on its own, but a few simple additions make it even more memorable.
- Vanilla ice cream for a creamy contrast to the warm cake.
- Freshly whipped cream for a light, airy topping.
- Chopped toasted pecans for crunch.
- A drizzle of caramel sauce for extra sweetness.
- Fresh banana slices for a simple garnish.
For a dinner party, serve small warm portions in dessert bowls with vanilla ice cream.
Make-Ahead Instructions
You can measure the dry cake mix and prepare the brown sugar and cinnamon mixture in advance. Store the components separately until you are ready to assemble the dessert.
For the best texture, slice the bananas and mix the wet cake ingredients shortly before cooking. Once assembled, cook the cake rather than leaving raw batter sitting at room temperature.
Storage Instructions
Allow leftovers to cool, then transfer them to an airtight container and refrigerate within two hours of cooking.
- Refrigerator: Store for up to 3 to 4 days.
- Freezer: Freeze portions in freezer-safe containers for up to 2 months for best quality.
- Reheating: Warm individual portions in the microwave in short intervals until heated through. Add a small spoonful of water or milk if the cake seems dry.
The banana topping may darken slightly during storage, but the dessert will still be enjoyable if stored properly.
Frequently Asked Questions
Can I use homemade cake batter?
Yes. A favorite yellow cake batter can replace the boxed mix. Use a recipe that produces approximately the same quantity of batter, and monitor the cooking time because different batters may cook at different rates.
Can I use frozen bananas?
Fresh bananas are recommended because frozen bananas release extra moisture as they thaw. If using frozen bananas, thaw and drain them well before adding them to the slow cooker.
Why is my cake still wet in the middle?
Slow cookers differ in heat output, and the center can take longer to cook than the edges. Continue cooking in short increments with the lid closed between checks. Make sure you are testing the cake layer rather than the moist banana sauce underneath.
Can I cook this dessert overnight?
It is not recommended to cook this cake overnight unless you can reliably control the cooking time. Overcooking can make the edges dry or overly dark while the banana layer becomes very soft.
Is this the same as traditional Bananas Foster?
Traditional Bananas Foster is a skillet dessert made with bananas, butter, brown sugar, cinnamon, and often rum, then served over ice cream. This slow cooker version is inspired by those flavors but adds a cake layer for a more substantial dessert.
