This pumpkin dessert lasagna stacks a buttery graham crust, spiced pumpkin cream, ladyfingers, and a white chocolate whipped layer into a chilled dessert that looks impressive and slices into neat squares.
It borrows the flavors of pumpkin pie but swaps the custard for a light cream cheese mousse, so there is only a short bake for the crust. After a few hours in the refrigerator, the layers set into a cool, creamy dessert for fall dinners and family gatherings.

Why This Pumpkin Dessert Lasagna Recipe Works
The graham crust is baked briefly so it turns crisp and golden, which gives the soft layers above it something firm to rest on. Cooling it fully keeps the mousse from melting into the base.
Beating the cream cheese until smooth before adding anything else prevents lumps in the pumpkin mousse. Whipped topping folded in at the end makes it light and spreadable.
Ladyfingers soften as the dessert chills, turning soft and tender between the two mousse layers. A final topping of white chocolate whipped cream, spiced chips, and pecans adds sweetness and crunch.
Ingredients for Pumpkin Dessert Lasagna
- 9 graham cracker sheets (about 1 sleeve)
- 6 ounces unsalted butter, melted (1 1/2 sticks)
- 8 ounces cream cheese, softened
- 1/4 cup heavy cream
- 1 cup powdered sugar
- 11 ounces pumpkin puree (not pumpkin pie filling)
- 1 1/2 teaspoons pumpkin pie spice
- 20 ounces whipped topping, thawed and divided (2 1/2 tubs of 8 ounces)
- 6 ounces white chocolate, melted
- 15 ladyfinger cookies
- 1 cup pumpkin spice chips
- 1 cup chopped pecans (optional)
Graham crackers and butter. They form a crisp, buttery crust that anchors the dessert.
Cream cheese. Softened cream cheese gives the mousse its tang and helps it hold its shape.
Pumpkin puree. Choose plain puree. Pumpkin pie filling is already sweetened and spiced.
Whipped topping. It lightens the mousse and makes the white chocolate layer spreadable.
Ladyfingers. They soak up moisture from the mousse and become soft and tender.
How to Make Pumpkin Dessert Lasagna
1. Make the crust Heat the oven to 350 degrees F. Crush the graham crackers in a zip top bag with a rolling pin, add the melted butter, and knead the bag until the crumbs look like wet sand.
2. Bake and cool the base Press the crumbs firmly into a 9×13 inch pan and bake for 6 to 8 minutes, until golden. Let the crust cool completely.
3. Beat the pumpkin mousse Beat the softened cream cheese until smooth and fluffy, then add the heavy cream. Mix in the powdered sugar, pumpkin puree, and pumpkin pie spice until no streaks remain.
4. Lighten the mousse Stir in one tub of the whipped topping, then whisk on high for 1 to 2 minutes until fluffy. Set the mousse aside.
5. Make the white chocolate layer In another bowl, whisk a second tub of whipped topping with the melted white chocolate until smooth.
6. Assemble the first layers Spread half of the pumpkin mousse over the cooled crust, then lay the ladyfingers on top in even rows.
7. Add the top layers Cover the ladyfingers with the remaining mousse and spread the white chocolate whipped layer over it. Finish with a thin layer of the remaining whipped topping, then scatter the spiced chips and pecans on top.
8. Chill until set Refrigerate for at least 2 hours before cutting so the layers firm up.
How to Serve Pumpkin Dessert Lasagna
Cut the dessert into squares and serve straight from the refrigerator. It pairs well with mini pumpkin Bundt cakes on a fall dessert table, or with a small scoop of vanilla bean creme brulee for a contrast in texture. A spoonful of dark chocolate mousse suits chocolate lovers, and a glass of strawberry blueberry kefir smoothie makes a lighter side.
How to Store and Reheat Pumpkin Dessert Lasagna
Cover the pan tightly and refrigerate for up to 3 days. Do not leave the dessert out for more than 2 hours, since it contains cream cheese and whipped topping. Freezing is not recommended because the texture turns watery after thawing.
Tips and Variations for Pumpkin Dessert Lasagna
Soften the cream cheese. Let it sit at room temperature briefly so it beats smooth without lumps.
Cool the crust fully. A warm crust melts the mousse and makes the layers slide.
Use plain puree. Pumpkin pie filling will make the dessert too sweet and too loose.
Cool the white chocolate. Let the melted chocolate cool for a few minutes before whisking it into the whipped topping so it does not deflate.
Use regular cream cheese. Full fat cream cheese gives a richer, firmer mousse than a low fat version.
Adjust the spice. Add a little more pumpkin pie spice for a stronger flavor or a little less for a milder one.
Chill overnight. A longer chill gives the cleanest squares.
Keep it cold. Follow the Purdue Extension guide to storing leftovers and refrigerate the dessert promptly after serving.
Frequently Asked Questions About Pumpkin Dessert Lasagna
Can I make pumpkin dessert lasagna the day before?
Yes. It needs at least 2 hours to chill, so making it a day ahead gives the layers extra time to set. Keep it covered in the refrigerator.
How long should pumpkin dessert lasagna chill before slicing?
Chill it for at least 2 hours so the layers firm up enough to cut into clean squares.
Can I use pumpkin pie filling in pumpkin dessert lasagna?
No. Pumpkin pie filling is already sweetened and spiced, so use plain pumpkin puree and add the spice yourself.
Why does the crust need to be baked?
A short bake sets the buttered crumbs into a crisp base that supports the soft layers. Cool it completely before adding the mousse.
Which toppings can I swap?
Mini chocolate chips, toffee bits, or toasted walnuts can replace the spiced chips and pecans. Leave the nuts off for a nut free dessert.
