Ingredients You’ll Need

All you need are a handful of simple ingredients that each bring something special to this fabulous Blueberry Lemon Icebox Cake. From the airy mascarpone to zesty lemon and juicy blueberries, every element plays its part to deliver layers of flavor, texture, and sunshiny color.

• Mascarpone Cheese: This creamy, Italian cheese keeps the filling rich but light and blends seamlessly with lemon for that fresh tang.
• Confectioners Sugar: Sweetens the cream mixture without any grittiness, giving the filling its signature silky texture.
• Lemon Zest: Freshly grated lemon zest adds bright, citrusy aroma and real lemon flavor—don’t skip it!
• Heavy Whipping Cream: Whips up into luscious peaks, making the filling light and airy while holding those beautiful layers together.
• Graham Crackers: The classic “cake” for any icebox dessert—once chilled, they soften to just the right melt-in-your-mouth texture.
• Blueberry Jam, Preserves, or Spread: For the deeply jammy blueberry layers. Use your favorite, or even homemade!
• Lemon Curd: Adds an extra burst of tartness and creamy lemon intensity between the layers.
• Fresh Blueberries: For garnish and a pop of juicy freshness—plus an extra round of blueberry sauce, if you want even more flavor.

Variations

One of the best things about this Blueberry Lemon Icebox Cake is how easily you can mix things up to suit your craving or what you’ve got in the fridge. Don’t be afraid to put your own twist on this classic—here are some ideas to get you started!

• Swap the Jam: Raspberries or blackberries make a lovely substitute for blueberries—just use your favorite jam or preserves.
• Cookie Crust: Try vanilla wafers or gingersnaps instead of graham crackers for a different flavor and crunch.
• Dairy-Free Version: Use coconut whipped topping and a vegan cream cheese alternative for a plant-based treat.
• Add a Boozy Twist: Brush the graham crackers with a splash of limoncello or blueberry liqueur for grown-up flavor.

How to Make Blueberry Lemon Icebox Cake

Step 1: Make the Lemon Mascarpone Mixture

Start by whisking together the mascarpone cheese, confectioners sugar, and that gloriously fragrant grated lemon zest. Go for a silky, smooth mixture—about a minute by hand, or a quick whirl in your mixer if you want to save some time. Set it aside; it’ll wait patiently for the next step.

Step 2: Whip the Cream and Combine

In a large bowl (stand mixer or hand mixer both work), whip your heavy cream until it’s just reached the soft peaks stage—think billowy, but not yet stiff. In two or three additions, fold in the mascarpone-lemon mixture, and continue to beat gently until it holds firmer peaks. This is where the filling gets its signature cloudlike texture.

Step 3: Reserve Frosting & Add Lemon Curd

Scoop out a third of your whipped mixture, wrap, and store in the fridge—this is your “frosting” for the final flourish. To the remaining whipped mixture, gently fold in half a cup of lemon curd until only tiny swirls remain. Be patient and light-handed so you don’t lose that glorious fluff.

Step 4: Layer the Cake

Line your loaf pan with plastic wrap (leave it hanging over the edges for easy unmolding later). Lay down a layer of graham crackers, breaking and fitting them as needed to cover the bottom. Top with a quarter of the whipped cream mixture, smoothing it all the way to the corners, then add a layer of blueberry jam, followed by lemon curd. Repeat this layering—crackers, cream, jam, curd—until all ingredients are used, finishing with a final layer of crackers on top.

Step 5: Chill and Set

Fold the plastic wrap edges over the top to seal. Now, let your Blueberry Lemon Icebox Cake do its magic in the freezer for at least 6–8 hours, or overnight. This deep chill is key for dreamy, sliceable layers.

Step 6: Unmold and Frost

Once fully set, invert the pan over your serving platter and carefully peel away the plastic wrap. Spread your reserved mascarpone cream over the top and sides for that bakery-worthy finish. A quick pop back in the freezer for 15 minutes ensures clean slicing and sets the frosting perfectly.

Step 7: Garnish and Serve

Mix fresh blueberries with some blueberry jam for a quick, fruity sauce, and serve it drizzled over each slice. Pop any remaining cake back in the freezer (if you’re lucky enough to have leftovers!).

How to Serve Blueberry Lemon Icebox Cake

Garnishes

The prettiest touch for this Blueberry Lemon Icebox Cake is a tumble of fresh blueberries on top, plus a swirl of extra blueberry jam or even a sprinkle of lemon zest for color. For true wow-factor, a few dots of lemon curd and a dusting of powdered sugar bring the bright, bakery look to your dessert table.

Side Dishes

This dreamy cake likes to be the star, but a simple pitcher of iced tea or a crisp glass of sparkling lemonade pairs perfectly with the zesty lemon and berry vibes. For a bigger spread, serve alongside a platter of fresh summer fruit or a scoop of vanilla ice cream.

Creative Ways to Present

For parties, try assembling mini Blueberry Lemon Icebox Cakes in individual parfait glasses—guests will love seeing those gorgeous layers. You can even make a “sheet cake” version in a square pan for easy potluck slicing. Dress it up with edible flowers or tiny lemon wedges for a truly showstopping presentation.

Make Ahead and Storage

Storing Leftovers

If you have leftover Blueberry Lemon Icebox Cake (lucky you!), simply wrap it tightly with plastic wrap and keep it stored in the freezer. It’ll stay fresh for several days and is always ready whenever you need a sweet treat.

Freezing

This cake is meant to be frozen, so you can easily make it days in advance. Once assembled and frosted, keep it tightly wrapped to prevent freezer odors and ice crystals—just add garnishes fresh before serving, if you like.

Reheating

No reheating needed—just slice the cake straight from the freezer and give it about 5-10 minutes at room temperature for the perfect texture. The creamy filling softens slightly, making each bite positively dreamy.
