I first made this dessert for a Fourth of July celebration three years ago, and now my family insists I bring it to every warm-weather gathering. The cool, creamy texture paired with bright lemon and juicy blueberries never fails to impress guests who always ask for the recipe.

Step-by-Step Instructions
- Create the Graham Cracker Base:
- Process graham crackers into fine crumbs using a food processor or place them in a ziplock bag and crush with a rolling pin until no large pieces remain. Mix crumbs thoroughly with sugar in a large bowl until combined. Pour in melted butter and stir until every crumb is moistened and mixture resembles wet sand. Transfer mixture to a 9x13 baking dish and press firmly across the entire bottom using the back of a measuring cup to create an even layer. Place in freezer for exactly 20 minutes to set.
- Prepare the Lemon Filling:
- In a medium bowl, combine the lemon pudding mix and half and half, whisking continuously for a full minute until completely smooth. Set aside for 5 minutes until mixture thickens noticeably. Meanwhile, in a large separate bowl, beat the very softened cream cheese and powdered sugar with an electric mixer on medium speed for 2 minutes until light and fluffy with no lumps remaining. Add the thickened pudding mixture to the cream cheese mixture and blend on low speed until fully incorporated, scraping down the sides of the bowl as needed. Gently fold in one entire container of Cool Whip using a rubber spatula with a light hand to maintain airiness, making sweeping motions from bottom to top until no white streaks remain.
- Assemble the Layers:
- Remove crust from freezer and spread the lemon mixture evenly over the chilled crust using an offset spatula, ensuring it reaches all corners. Carefully spoon blueberry pie filling over the lemon layer in dollops, then gently spread into an even layer without disturbing the lemon layer beneath. Top with the second container of Cool Whip, spreading in smooth, even motions to create a fluffy cloud-like topping that completely covers the blueberry layer.
- Chill and Serve:
- Cover the dessert with plastic wrap without touching the surface and refrigerate for a minimum of 8 hours or ideally overnight to allow flavors to meld and layers to set properly. When ready to serve, cut into squares with a clean, sharp knife, wiping between cuts for neat presentation.
The lemon layer is truly the star of this dessert. I discovered through many test batches that allowing the cream cheese to reach complete room temperature is crucial. One summer, I tried to rush this step and ended up with tiny lumps throughout my otherwise perfect dessert. My grandmother actually commented that the slightly speckled appearance reminded her of lemon zest, but I knew better and have never skipped proper softening since!
Perfect Make-Ahead Dessert
This dessert actually improves with time, making it ideal for preparing in advance of gatherings. The graham cracker crust softens slightly while maintaining its integrity, and the flavors meld beautifully as it rests in the refrigerator. You can comfortably make this up to 48 hours before serving, which allows you to focus on other preparations when entertaining. Just be sure to cover it tightly with plastic wrap to prevent it from absorbing refrigerator odors or forming a skin on top of the Cool Whip layer.
Creative Variations
While the classic blueberry version holds a special place in my heart, this versatile dessert welcomes adaptation based on seasonal fruit availability or personal preferences. Try substituting the blueberry pie filling with strawberry pie filling for a pretty pink layer. Cherry pie filling creates a striking red layer perfect for Christmas gatherings. For a truly homemade approach, create your own fruit topping by cooking fresh fruit with sugar and cornstarch until thickened. Peach filling pairs wonderfully with the lemon layer during late summer when peaches are at their peak. The lemon layer itself can also be transformed by using different pudding flavors like vanilla, cheesecake, or even white chocolate.
Presentation Tips
Though delicious on its own, this dessert can be elevated with thoughtful garnishing. For special occasions, I reserve a few tablespoons of graham cracker crumbs to sprinkle along the edges of the dessert before serving. This creates a finished look and hints at what awaits beneath the creamy layers. Fresh fruit makes an outstanding garnish small clusters of fresh blueberries, thin lemon slices, or even a light dusting of lemon zest add visual appeal and reinforce the flavors. For elegant individual servings, consider preparing in clear glass trifle cups or small mason jars, creating visible layers that impress before the first bite.
