Blueberry-Lemon Icebox Cake – tender pound cake layered between fluffy lemon curd mascarpone cream and a fresh blueberry sauce for a wonderful frozen dessert you’ll be thrilled to serve your guests.
Your guests will be thrilled too … especially if you slice it nice and thick, and glob another spoonful of the blueberry sauce right on top. I love a make-ahead dessert that is easily sliced as needed, and this Blueberry-Lemon Icebox Cake is needed at our house!
First of all … there are hard working men in my kitchen today. They’re not cooking but doing something so much more exciting. They’re laying a new tile floor. Over the last four months I’ve mentioned our kitchen renovation and hinted at the constant problems. If something could go wrong, it did. However, after a tremendous amount of perseverance, we have new cabinets, countertops, most of our appliances have been re-installed and today they’re laying the tile floor. I love our team and they’ve gone above and beyond when it comes to seeing this through.
With temperatures near 100 degrees here in Virginia today, I know our construction team will enjoy this cold and creamy dessert after working hard in my kitchen all day!
These guys are great taste-testers and I can’t wait to hear what they say about this one. Even though I like them both very much, I’m ready for them to be gone for good so I can get my house back, and especially my dishwasher! Oh how I’ve missed my dishwasher. I am starting to feel like a food blogger without a kitchen. Even though my kitchen may be functional in a few days, there is still plenty of detail work to be done. It’s not over yet but prayers are being answered today!
Icebox cakes are so much fun to make. Most recipes include layers of your favorite ice cream, and I love those too!
However, there is something so refreshing about this lemon curd infused mascarpone cream. The cream freezes beautifully and once it rests at room temperature for a few minutes, it softens into a light and fluffy cloud of lemon, without melting into a puddle. Don’t get me wrong … I love a good ice cream puddle but on really hot days – this is perfect because it won’t melt completely.
If you don’t want to make homemade pound cake, no worries; buy a pre-made or frozen cake and slice it up.
Not into homemade blueberry sauce? Buy a good jar of blueberry jam … we won’t tell.
Never made easy homemade lemon curd? You can buy that too but don’t skip this homemade lemon mascarpone cream. With only 5 ingredients the cream mixes up in just a few minutes and really makes this dessert something special.
Lemons and blueberries are a classic combination for desserts and baked goods. Each layer of this Blueberry-Lemon Icebox Cake stands on it’s own but also blends together beautifully.

- For the blueberry sauce:
- 3 cups fresh blueberries, plus ⅓ cup, divided
- ½ cup granulated sugar
- 2 tablespoons water
- juice of ½ a large lemon (about 1 tablespoon)
For the lemon cream:
- 8 ounces mascarpone cheese, room temperature
- ¾ cup powdered sugar
- zest of 1 large lemon
- 2 cups (16-ounces) heavy whipping cream
- 1 cup of store-bought or homemade lemon curd, divided
- 1 9x5 pound cake, trimmed of top, bottom and sides (saved for another use)
- To make the blueberry sauce combine 3 cups of fresh (or frozen) blueberries with ½ cup granulated sugar and 2 tablespoons water in a deep saucepan. Heat on medium until the mixtures begins to boil. Reduce the heat slightly to maintain a simmer, and cook until the blueberries pop and the sauce thickens, about 5 minutes. Add the lemon juice and cook until the mixture is almost reduced by half (about 10 minutes.) You will need 1½ cups of sauce. Remove from the heat and cool. Refrigerate until ready to use. (Keep the extra ⅓ cup of fresh blueberries ready - they are added at the end.)
- When ready to make the icebox cake, line a 9x5 inch loaf pan with plastic wrap making sure there is a lot of extra hangover on all sides. Set aside.
- Prepare the pound cake by slicing into ½" pieces removing the dark ends, and sides if desired for a prettier presentation. (freeze the extra pound cake pieces for another use like adding to a dollop of Greek yogurt and a drizzle with honey or combine with your favorite ice cream.) Set aside.
- In the bowl of a stand mixer combine the mascarpone cheese, powdered sugar, and lemon zest. Blend until smooth. Turn the mixer on low and slowly add the whipping cream until it's incorporated and starting to thicken. Increase the speed to medium, then high, and beat until medium peaks form. It won't take long.
- Transfer ⅓ of the cream to a container with a tight fitting lid and refrigerate until needed. This will be used to "ice" the cake.
- Gently fold in ½ cup of lemon curd into the remaining mascarpone mixture. Now you're ready to assemble the icebox cake.
- Place a layer of pound cake in the bottom of the prepared pan, cutting to fit as needed. Spread ¼ of the lemon cream over the cake and use the back of a spoon to smooth the surface (place the remaining lemon cream in the refrigerator until needed again).
- Place the pan in the freezer for 5-10 minutes, then spoon ½ cup of the blueberry sauce in mounds over the lemon cream. Spread gently with a clean spoon to cover the cream. Place the pan back in the freezer for about 10 minutes.
- Drizzle ¼ cup of the lemon curd over the blueberry sauce. Spoon ⅓ of the remaining lemon cream over the curd and smooth evenly with the back of a spoon. Top with another layer of pound cake.
- Repeat the process with ½ of the remaining lemon cream, ½ cup blueberry sauce, and the remaining lemon curd, freezing between layers as needed.
- Finish with a layer of lemon cream and a final layer of pound cake. The cake may extend over the top of the pan depending on how thick you cut the pound cake. This is where you need that extra long pieces of plastic wrap to come up and over the cake to hold it all in.
- Wrap the entire cake in plastic wrap and freeze for at least 8 hours or overnight.
- When ready to serve, remove the plastic wrap and invert the cake onto a serving platter. Peel off the plastic wrap and trim the sides of the cake with a knife, if desired, to make a straight edge.
- Spread the top and sides of the cake with the remaining mascarpone cream. If needed, whisk the cream until soft peaks form again.
- Place the iced cake in the freezer at least 15 minutes or until ready to serve.
- To serve, mix the ⅓ cup fresh blueberries into the remaining blueberry sauce and spoon over the cake.
Mascarpone cream and the layering adapted from a recipe in Bon Appetit Magazine, July 2016
Blueberry sauce can be replaced with good quality blueberry jam.
Homemade lemon curd can be replaced with store-bought.
You may have leftover pound cake depending on how thick it was sliced.
Most of all, don’t be put-off by the layering and assembly of the icebox cake.
Once all the components are ready, it comes together easily. Take a little extra time to pop the cake in the freezer after adding each layer – if only for ten minutes or so. It will make the final product much prettier and a little more tidy when sliced.
