This lemon lasagna dessert has become my go-to summer treat for gatherings where I need something impressive without spending hours in a hot kitchen. The bright citrus layers and creamy texture create the perfect balance of tangy and sweet that disappears quickly at every potluck.
I first made this for a garden party when temperatures hit 95 degrees and needed something refreshing. The bright yellow layers and cool creaminess had guests requesting the recipe before they even finished their first slice.
Ingredients
- Lemon sandwich cookies: Providing both the crust and optional garnish with their perfect balance of sweet cookie and tangy filling
- Cream cheese: Creating a rich and tangy base for the second layer that complements the lemon beautifully
- Lemon pie filling: Delivering concentrated citrus flavor without requiring fresh lemons when not in season
- Whipped topping: Bringing lightness to multiple layers while requiring zero effort
- Vanilla pudding mix: Acting as a stabilizer for the whipped layers ensuring perfect slices every time
- Heavy cream: Thinning the lemon filling to the perfect consistency while adding richness
- Lemon juice: Enhancing the natural citrus flavor with bright acidity that balances the sweetness
- Lemon zest: Optional but adds beautiful color and concentrated flavor bursts in each bite
Step-by-Step Instructions
- Create the Cookie Crust:
- Process lemon sandwich cookies in a food processor until finely ground resembling coarse sand then pour in melted butter and pulse until the mixture looks like wet sand that clumps when pressed between your fingers. Press this mixture firmly into your prepared pan using the bottom of a measuring cup to create an even compact layer.
- Prepare the Cream Cheese Layer:
- Beat room temperature cream cheese with sugar until completely smooth with no lumps about 2 minutes on medium speed. Add room temperature sour cream and continue beating until incorporated fully waiting until the mixture looks silky and uniform. Gently fold in 2 cups of whipped topping using a rubber spatula with a light hand folding from bottom to top to maintain maximum fluffiness.
- Create the Lemon Layer:
- Whisk the lemon pie filling heavy cream and fresh lemon juice in a large bowl until completely combined and smooth taking care to break up any clumps from the pie filling. Add 2½ tablespoons of vanilla pudding mix whisking continuously until the mixture thickens slightly which happens almost immediately. Spread this mixture carefully over the cream cheese layer using an offset spatula for the smoothest finish.
- Finish with Stabilized Whipped Topping:
- Mix the remaining tablespoon of pudding mix into the leftover whipped topping creating a more stable final layer that will hold its shape when sliced. Spread this across the top of the dessert in decorative swirls or peaks reaching all the way to the edges to seal in the lemon layer. Refrigerate for at least 2 hours but preferably 4 or overnight allowing all layers to set properly.

The lemon pudding layer is truly the star of this dessert. I discovered that adding that extra squeeze of fresh lemon juice brightens the canned filling tremendously taking it from good to spectacular. My grandson always begs to lick the pudding bowl which I happily allow since watching his face pucker from the tartness brings me joy every time.
Make Ahead and Storage Tips
This lemon lasagna actually improves with time as the flavors meld together in the refrigerator. Make it up to 24 hours before serving for the best texture and flavor development. The dessert will keep well refrigerated for up to 4 days though the crust may soften slightly over time. I recommend covering with plastic wrap rather than aluminum foil which can react with the acidic lemon.
Smart Substitutions
For a lighter version use Neufchâtel cheese in place of regular cream cheese and light sour cream which reduces calories without sacrificing flavor. If lemon sandwich cookies are unavailable substitute golden Oreos mixed with 1 tablespoon lemon zest. Fresh homemade lemon curd can replace canned pie filling for a more intense lemon flavor though you may need to add an extra tablespoon of pudding mix to achieve the proper thickness.
Serving Suggestions
For an elegant presentation serve squares on chilled dessert plates with a small dollop of whipped cream and a fresh raspberry or blackberry on top. The contrast between the bright yellow dessert and dark berries creates a stunning visual. For summer gatherings I like to serve this alongside a pitcher of iced tea with lemon slices and fresh mint which complements the citrus flavors beautifully.
Seasonal Variations
During winter holidays add a drop of yellow food coloring to enhance the lemon layer and sprinkle with red and green sprinkles for a festive touch. In spring add 1 tablespoon of poppy seeds to the cream cheese layer for a lemon poppy seed variation that adds subtle crunch. Summer calls for fresh berries scattered between layers or as garnish creating a beautiful contrast in both flavor and color.
