There’s something about a weekend afternoon that calls for a dessert that’s both playful and comforting. This Jello Banana Split Cake brings together the fun of a classic banana split with the ease of a crowd-pleasing layered cake. It’s the kind of treat that sparks smiles—bright colors, soft textures, and that familiar combination of fruit, cream, and just the right touch of sweetness.
I remember the last time I made this for a small get-together. The kitchen smelled faintly of vanilla and warm cake, but my mind kept wandering to the moment when I’d pour the strawberry Jello layer over the bananas. I was a little worried it might slide right off or not set quite right, but it settled perfectly — shiny and inviting. I almost forgot to take a photo before the first bite happened; someone swooped in, and I wasn’t fast enough. It’s a bit of a showstopper, but also forgiving if you’re juggling more than one thing at a time.
Why You’ll Love It:
- It’s a colorful, nostalgic dessert with fresh bananas and creamy pudding that’s surprisingly simple to pull together.

Jello Banana Split Cake

Description
A delightful and colorful dessert combining the flavors of a classic banana split with a moist cake base, layered with creamy pudding, fresh bananas, and topped with vibrant Jello and whipped cream.
Ingredients
1 box (15.25 ounces) yellow cake mix
1 cup water
1/3 cup vegetable oil
3 large eggs
1 box (3.4 ounces) instant vanilla pudding mix
2 cups cold milk
3 medium ripe bananas, sliced
1 package (3 ounces) strawberry Jello gelatin
1 cup boiling water
1 cup cold water
2 cups heavy whipping cream
1/4 cup powdered sugar
1 teaspoon vanilla extract
1/2 cup maraschino cherries, drained and halved
1/2 cup chopped walnuts
Instructions
Preheat the oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan.
In a large bowl, combine the yellow cake mix, water, vegetable oil, and eggs. Beat on medium speed for 2 minutes until smooth.
Pour the batter into the prepared baking pan and bake for 30 to 35 minutes or until a toothpick inserted into the center comes out clean.
Remove the cake from the oven and allow it to cool completely in the pan on a wire rack.
In a medium bowl, whisk together the instant vanilla pudding mix and cold milk until thickened, about 2 minutes. Refrigerate until ready to use.
In a separate bowl, dissolve the strawberry Jello gelatin in 1 cup boiling water. Stir until completely dissolved, then add 1 cup cold water. Refrigerate until the gelatin is thick but not fully set, about 30 minutes.
In a large mixing bowl, beat the heavy whipping cream, powdered sugar, and vanilla extract together until stiff peaks form. Refrigerate until ready to assemble.
Once the cake is completely cooled, spread the prepared vanilla pudding evenly over the top.
Arrange the sliced bananas evenly over the pudding layer.
Carefully spoon the thickened strawberry Jello over the bananas, spreading gently to cover them completely.
Refrigerate the cake for at least 1 hour to allow the Jello to set.
Before serving, spread the whipped cream evenly over the top of the set Jello layer.
Decorate the top with maraschino cherry halves and chopped walnuts.
Cut into squares and serve chilled.

Kitchen Notes: You don’t need any special kitchen gadgets for this cake—just a good-sized mixing bowl and a pan that fits a 9×13 inch cake. When serving, I like to pair it with a simple cup of coffee or tea to balance the sweetness. If you want to switch things up, sometimes I swap the strawberry Jello for raspberry, or scatter a few mini chocolate chips over the whipped cream for a little extra texture. Also, using very ripe bananas makes a difference; they blend smoothly with the pudding layer. I haven’t tested it, but I imagine a sprinkle of toasted coconut could add a nice tropical twist, too.
FAQ
Can I make this cake a day ahead?
Yes! In fact, letting it chill overnight helps the layers set perfectly and the flavors meld.
Will the bananas brown?
They stay fresh under the pudding and Jello layers, but it’s best to serve within a couple of days for the brightest look and taste.
Can I use fresh whipped cream instead of store-bought?
Absolutely, and it makes a lovely difference in texture and flavor.
