This playful 5-ingredient baked dessert turns pantry-staple lasagna noodles into a fun, National Banana Split Day-inspired treat with layers of banana, chocolate, and a creamy finish. It is the kind of recipe that feels a little unexpected at first, but that is exactly why busy home cooks love it: minimal ingredients, easy assembly, and a nostalgic banana-split flavor that comes out warm, sweet, and scoopable from the oven.
Serve this dessert warm with extra banana slices, a drizzle of chocolate syrup, or a small scoop of vanilla ice cream to lean into the banana split theme. It also pairs well with coffee after dinner or with a cold glass of milk for a casual family dessert, and if you are bringing it to a potluck, a spoonful of whipped topping on each serving makes it feel a little more special.
5-Ingredient Oven Baked National Banana Split Day Dessert
Servings: 8
Ingredients
9 whole uncooked lasagna noodles
4 ripe bananas, sliced
2 cups milk
1 cup semi-sweet chocolate chips
2 cups whipped topping
Directions
1. Preheat the oven to 375°F and lightly coat a metal roasting pan with nonstick spray or a thin layer of butter to help prevent sticking.
2. Pour a thin layer of milk into the bottom of the pan, then arrange 3 whole uncooked lasagna noodles in a single layer. Scatter some of the banana slices and chocolate chips over the noodles, then spoon on a light layer of whipped topping.
3. Repeat the layering two more times with the remaining milk, noodles, banana slices, chocolate chips, and whipped topping, ending with whipped topping on top. Cover the pan tightly with foil.
4. Bake for 35 to 40 minutes, or until the noodles are tender and the top looks softly set. Remove the foil for the last 5 minutes if you want a little color on top.
5. Let the dessert rest for 10 to 15 minutes before scooping. Serve warm, topped with any extra banana slices or a little extra whipped topping if desired.
Variations & Tips
Add a cherry finish: For an even more classic banana split vibe, top each serving with a maraschino cherry right before serving. It adds color and makes the dessert look festive with almost no extra effort.
Use foil well: Keeping the pan tightly covered for most of the bake helps the lasagna noodles soften properly. If the pan seems dry when you check it, add a small splash of milk before returning it to the oven.
Make it more chocolatey: If your family loves rich desserts, drizzle a little chocolate syrup over each serving. The base recipe stays at 5 ingredients, but this is an easy serving-time upgrade for special occasions.
Serve it fresh: This dessert is best the day it is made, when the bananas still taste bright and the texture is soft and creamy. If you do make it ahead, reheat gently and add fresh banana slices right before serving.
