Giant Sheet Pan Banana Pudding Lasagna – Crowd-Pleasing Dessert!

Hi there, food lover! 👋

Ready to dive into a dessert so nostalgic, creamy, and wildly crowd-pleasing that it practically disappears the second it hits the table? Today we’re making a Giant Sheet Pan Banana Pudding Lasagna, a grand, party-sized twist on classic Southern banana pudding. 🍌🍰

This dessert is everything you adore about the original—velvety pudding, fluffy whipped cream, soft bananas, and those irresistible vanilla wafers—but built into glorious lasagna-style layers on a sheet pan. That means more slices, more smiles, and more people begging you for the recipe. It’s perfect for potlucks, BBQs, holidays, birthdays, or any moment you want to serve something comforting that feels like a warm hug from the kitchen.

Traditionally, banana pudding is kept simple and served chilled, often featuring a from-scratch custard or pudding mix depending on the cook. Our sheet pan version honors that tradition while stretching it into a delightful showstopper. The magic comes from its scale, its airy whipped topping, and the way the layers settle together as it chills—making each bite a dreamy scoop of creaminess.

Get ready to feed a crowd and win serious dessert points. Let’s build this beauty! 😋✨

Ingredients

For the Pudding Layer

• 2 boxes (5.1 oz each) instant vanilla pudding mix
• 6 cups cold whole milk
• 1 can (14 oz) sweetened condensed milk
• 1 tbsp vanilla extract

For the Whipped Layer

• 3 cups heavy whipping cream
• 1/2 cup powdered sugar
• 1 tsp vanilla extract

For the Layers & Assembly

• 1–2 boxes vanilla wafer cookies (enough to cover sheet pan twice)
• 6–8 ripe bananas, sliced
• Optional: crushed wafer crumbs for topping
• Optional: caramel drizzle for serving

Step-by-Step Directions

1. Prepare your sheet pan.
   Use a deep, rimmed sheet pan (also called a jelly roll pan). Line with parchment if desired for clean slicing later.
2. Mix the pudding.
   In a large bowl, whisk the pudding mix with cold milk until thickening begins. Add sweetened condensed milk and vanilla extract. Whisk until smooth and creamy. Chill 10 minutes.
3. Whip the cream.
   In a chilled mixing bowl, beat heavy cream, powdered sugar, and vanilla until stiff peaks form. Set aside.
4. Create the first cookie layer.
   Arrange vanilla wafers across the entire bottom of the sheet pan, fitting them snugly together.
5. Add bananas.
   Lay an even layer of banana slices over the cookies. This ensures every bite has banana goodness.
6. Spread pudding.
   Pour half of the prepared pudding over the bananas and cookies. Gently smooth with a spatula.
7. Second cookie layer.
   Add another full layer of wafers on top of the pudding. Lightly press into place.
8. More bananas + pudding.
   Slice the remaining bananas and scatter over the cookies. Pour the remaining pudding on top and smooth again.
9. Top with whipped cream.
   Generously spread the whipped cream across the entire surface until fully covered and fluffy.
10. Chill.
    Refrigerate at least 4 hours (overnight is even better) to allow the layers to meld into delicious harmony.
11. Finish & serve.
    Sprinkle with crushed wafers or drizzle with caramel. Slice into squares and watch it disappear! 🍌✨
