Creamy vanilla pudding, fluffy whipped cream, ripe bananas, and graham crackers come together in this no-bake banana icebox cake. It’s an easy make-ahead dessert that slices beautifully after an overnight chill.
Chill a mixing bowl and beaters. Add heavy whipping cream, powdered sugar, vanilla, and salt to the bowl and whip to medium-stiff peaks. Set aside.
In a separate large bowl, whisk instant vanilla pudding mix with cold whole milk for about 2 minutes until thickened.
Fold most of the whipped cream into the pudding until light and smooth, reserving about 1 cup of whipped cream for topping.
Slice bananas and gently toss with lemon juice to slow browning.
Line the bottom of a 9x13 inch baking dish with a single layer of graham cracker sheets, breaking pieces as needed to cover the surface.
Spread half of the pudding-cream mixture over the crackers. Top with half of the banana slices in an even layer.
Add a second layer of graham crackers, spread the remaining pudding-cream mixture over them, and top with the remaining banana slices. Finish with a final layer of graham crackers and spread the reserved whipped cream over the top.
Cover tightly and refrigerate at least 4 hours, preferably overnight, until the crackers soften and the cake slices cleanly. Slice and serve cold.
Notes
For extra flavor, sprinkle the top with crushed graham crumbs or shaved chocolate before chilling. Swap vanilla pudding for banana or cheesecake pudding if desired. The cake keeps well, covered and refrigerated, for up to 3 days.
