This blueberry lemon icebox cake is a fresh, no-bake summer dessert that combines bright lemon cheesecake, homemade blueberry pie filling, crunchy graham crackers, and piped whipped cream into a beautiful layered treat. It’s easy to assemble and becomes wonderfully firm after chilling, making it perfect for potlucks, picnics, or warm evenings.
Blueberry Lemon Icebox Cake
If you love berries, this dessert showcases them beautifully. The tang of fresh lemon balances the sweetness of the blueberry filling, and the cream cheese layer, stabilized with a little gelatin, stays soft yet sliceable after chilling. Honey graham crackers add a familiar, comforting crunch between the layers.
The recipe works equally well with fresh or frozen blueberries. Smaller wild blueberries offer intense flavor, but regular berries are fine too. The blueberry pie filling is simple—just blueberries, sugar, lemon juice, and cornstarch—cooked until thick. Keeping the lemon bright in the cheesecake layer prevents the blueberry from overpowering the dessert.
Blueberry Pie Filling
This quick, four-ingredient pie filling uses blueberries, sugar, lemon juice, and cornstarch. To avoid lumps, whisk the sugar and cornstarch together first, then slowly add the lemon juice while whisking. Add the blueberries and simmer on medium heat, mashing slightly as they soften, and cook until the mixture thickens and becomes glossy. The filling cools quickly and can be used warm or chilled when assembling the cake.
Tips for a pretty icebox cake
To make the finished cake more attractive, pipe the whipped cream topping using a star tip such as Wilton 4B or 1M, and finish with a light sprinkle of fresh lemon zest for color and extra brightness. Assemble the cake in a 9×13 pan for neat layers, cover tightly, and chill until the cheesecake layer is fully set—ideally overnight for best results.
Helpful tips:
- Use honey graham crackers rather than cinnamon varieties; cinnamon can clash with the bright lemon and blueberry flavors.
- The cheesecake mixture may seem thin when you first mix it; it will firm up as it chills.
- Always use fresh lemon juice for the best citrus flavor.
- If you prefer convenience, canned blueberry pie filling can substitute for the homemade filling.

- 1 tablespoon water (for gelatin)
- 8 ounces cream cheese, room temperature
- 3/4 cup granulated sugar
- 1 tablespoon lemon zest
- 1 tablespoon butter, room temperature
- 1 cup heavy whipping cream
- 3 tablespoons powdered sugar
- 20–21 honey graham crackers
Topping
- 3/4 cup heavy whipping cream (for garnish)
- 2 tablespoons powdered sugar

Instructions
Blueberry Pie Filling
- In a medium saucepan, whisk together the sugar and cornstarch until combined.
- Slowly whisk in the lemon juice until smooth.
- Add the blueberries and heat over medium. As the berries soften, mash slightly and stir.
- Bring to a boil and simmer, stirring constantly, for about 5 minutes until the filling thickens and turns clear and glossy. Remove from heat and cool.
Lemon Cheesecake Filling
- In a small microwave-safe bowl, combine the gelatin, 4 tablespoons lemon juice, and 1 tablespoon water. Let sit 10 minutes until the gelatin blooms.
- In a large bowl, beat the cream cheese and 3/4 cup sugar until smooth. Add lemon zest and butter and mix until combined.
- In a separate bowl, whip 1 cup heavy cream with 3 tablespoons powdered sugar to stiff peaks.
- Microwave the bloomed gelatin for about 30 seconds until fully liquid. Stir and let cool slightly.
- Beat the cooled gelatin into the cream cheese mixture, then fold in the whipped cream until smooth.
Assemble
- Arrange 5 graham crackers in the bottom of a 9×13 pan, breaking one to fit as needed.
- Spread one-third of the cheesecake mixture over the crackers.
- Top with half the blueberry filling, adding in dollops and spreading gently to avoid disturbing the cheesecake layer.
- Add another layer of graham crackers, then repeat with remaining cheesecake, blueberry filling, and crackers. Finish with the remaining cheesecake layer on top.
- Cover with plastic wrap and chill until the top cheesecake layer is firm, 1–2 hours, but preferably at least 4 hours or overnight.
Topping
- Whip 3/4 cup heavy cream with 2 tablespoons powdered sugar to stiff peaks.
- Pipe whipped cream stars across the top using a star piping tip (Wilton 4B or 1M).
- Sprinkle fresh lemon zest over the whipped cream.
