This 5-ingredient slow cooker banana pudding tastes just like the vintage version my grandmother set out every spring when the first warm breeze rolled across the fields. It’s built on simple pantry staples and those familiar vanilla wafers, turning into a creamy, custardy dessert with a soft crumble on top as it bakes low and slow. You stir it together in minutes, let the slow cooker do the work, and end up with a cozy, old-fashioned pudding that feels right at home on a weeknight table but special enough for Sunday supper.
Serve this banana pudding warm right from the slow cooker, spooned into small bowls so you catch both the silky custard and the soft, crumbly vanilla wafer topping. A little whipped cream on top never hurts, and a few extra vanilla wafers tucked in the side make it feel like company’s coming. It pairs nicely with a cup of coffee after supper or a glass of cold milk for the kids. If you’re serving a bigger meal, it’s especially lovely after something simple and comforting like roast chicken or meatloaf with mashed potatoes.
5-Ingredient Slow Cooker Vintage Banana PuddingServings: 6
Ingredients
3 large ripe bananas, sliced
2 cups whole milk
1 cup granulated sugar
4 large eggs
3 cups vanilla wafers, lightly crushed (plus a few whole wafers for garnish, optional)
Directions
Lightly grease the inside of a medium slow cooker (about 4-quart) with butter or nonstick spray to help keep the pudding from sticking.
In a large mixing bowl, whisk together the whole milk, granulated sugar, and eggs until the sugar is mostly dissolved and the mixture is smooth and well combined. This will be your simple custard base.
Scatter half of the lightly crushed vanilla wafers evenly over the bottom of the slow cooker, making a loose, crumbly layer.
Arrange half of the sliced bananas over the wafers in an even layer, tucking them into the crumbs so they’re nestled but not packed tight.
Pour about half of the custard mixture gently over the bananas and wafers, letting it seep down into the layers.
Repeat with the remaining crushed vanilla wafers and remaining banana slices, then pour the rest of the custard over the top, making sure all the bananas are mostly covered so they stay tender.
Place a clean kitchen towel over the slow cooker crock, then set the lid on top of the towel. (The towel will catch excess moisture so the top stays glossy and lightly set instead of watery.)
Cook on LOW for 2 1/2 to 3 hours, or until the custard is just set around the edges and the center still has a gentle wobble when you jiggle the crock. The top should look creamy with a soft, darker crumbly wafer layer.
Turn off the slow cooker, remove the lid and towel carefully to avoid dripping water onto the pudding, and let the pudding stand uncovered for about 20 to 30 minutes. It will finish setting and thicken slightly as it cools, while staying soft and spoonable.
Spoon the warm pudding into bowls, making sure each serving has some of the creamy custard and the crumbly vanilla wafer topping. If you like, garnish with a few whole vanilla wafers just before serving. Store any leftovers covered in the refrigerator and enjoy within 2 days.
Variations & Tips
For a slightly richer custard like my grandmother used to make for company, you can swap 1/2 cup of the whole milk for heavy cream. If you prefer a stronger vanilla flavor, stir 1 to 2 teaspoons of vanilla extract into the custard mixture before cooking (this will add an extra ingredient beyond the core 5, but it’s a nice touch when you have it). For a lighter sweetness, reduce the sugar to 3/4 cup, especially if your bananas are very ripe. If you like more texture on top, reserve 1/2 cup of the crushed vanilla wafers and sprinkle them over the surface during the last 30 minutes of cooking so they stay a bit more crumbly. You can also add a pinch of ground cinnamon or nutmeg to the custard for a gentle warm spice note that fits well with old-fashioned Midwestern baking. Food safety tips: Use only ripe, not spoiled, bananas—look for speckled yellow, not black and mushy. Make sure the pudding reaches a safe temperature; cooking on LOW for at least 2 1/2 hours in a covered slow cooker will fully cook the eggs, but if your slow cooker runs cool, you can extend the time slightly until the custard is set at the edges and no longer thin. Cool leftovers promptly and refrigerate within 2 hours; because this dessert contains eggs and dairy, do not leave it at room temperature for extended periods. Reheat leftovers gently in the microwave until just warm, not boiling, to keep the custard from curdling.
