How to Make Blueberry Lemon Icebox Cake

Prepare the Blueberry Sauce: In a small bowl, whisk together 2 teaspoons of cornstarch, 2 teaspoons of fresh lemon juice, and 1 tablespoon of warm water until smooth. In a small saucepan over medium heat, combine 2 cups of blueberries and 2 tablespoons of granulated sugar. Stir continuously for about 3 minutes, allowing the blueberries to release their juices. Stir in the cornstarch mixture and keep stirring for another 2-3 minutes. As it thickens, gently smash some blueberries with the back of a spoon. Once thickened, remove from heat and stir in 1 teaspoon of lemon zest. Set aside to cool completely; placing it in the fridge can speed up this process.
Prepare the Loaf Pan: Line a 9×5-inch loaf pan with plastic wrap, ensuring there is an overhang to make it easy to lift the cake out later.
Whip the Cream: Using a hand mixer or stand mixer with a whisk attachment, whip 2 cups of cold heavy cream on medium-high speed until soft peaks form, about 3 minutes. Once whipped, transfer to another bowl. In the same mixing bowl, beat 4 ounces of softened cream cheese on high speed until completely smooth, about 1 minute. Add in 6 tablespoons of confectioners’ sugar, 1 tablespoon of fresh lemon juice, and 1 teaspoon of lemon zest, and continue mixing until well combined and creamy. Gently fold the whipped cream into the cream cheese mixture, being careful not to over-mix.
Layer the Cake: To start layering, spread a thin layer of the cream mixture in the bottom of the prepared loaf pan. Fit in graham crackers in a single layer, breaking them if necessary. Spread approximately 3/4 cup of the cream filling over the crackers, followed by half of the blueberry sauce. Add another 3/4 cup of cream filling, a second layer of graham crackers, and 3/4 cup of cream filling again. Then, add the remaining blueberry sauce over that layer, followed by another 3/4 cup of cream filling. Finally, place the rest of the graham crackers on top and add the remaining cream filling, smoothing it out on top.
Chill the Cake: Cover the loaf pan with plastic wrap or aluminum foil and put it in the freezer to set for at least 4 hours or overnight.
Serve & Garnish: Before serving, allow the cake to rest in the refrigerator for about 1 hour or at room temperature for about 10-15 minutes to soften slightly. Using the plastic wrap overhang, carefully lift the cake from the pan. Garnish with fresh blueberries, mint, or lemon slices before slicing into portions and serving chilled.
Store Leftovers: Any leftovers can be covered and stored in the refrigerator for 2-3 days, or if you want, freeze for up to 3 months. Just remember to let it soften again before enjoying!

Storing & Reheating

To store your Blueberry Lemon Icebox Cake, keep it covered in the refrigerator for 2-3 days. For longer storage, it can be frozen in an airtight container for up to 3 months. If you do freeze it, simply allow it to soften in the fridge for an hour or at room temperature for 10-15 minutes before serving. Be mindful that the texture may change slightly after freezing, but a quick refresh in the fridge can help bring it back to life.

Chef’s Helpful Tips

To avoid a grainy texture in your cream filling, ensure the cream cheese is fully softened before mixing.
Always use cold heavy cream for whipping; it incorporates air better for a fluffy filling.
If you love lemon, feel free to adjust the amount of zest or juice to suit your taste preferences.
For a fun twist, add some crushed mint leaves into the blueberry sauce for a refreshing herbal note.
Make this icebox cake a day in advance—it’s even better when allowed to sit overnight for the flavors to meld!
