Lemon Icebox Cake was inspired by the classic pie. This silky, refrigerated cake has the popular filling made with lemon juice and sweet condensed milk. It’s the perfect marriage of tangy, tart lemon filling and buttery cake and crowned with fluffy whipped cream.

I grew up in a household where my parents didn’t like chocolate. I know right? It is hard to believe. Therefore, I’m not a huge fan of chocolate. Even now, I’d rather have almost any dessert flavor instead of a chocolate dessert. The exception to that would be brownies and this chocolate cake. I mean, brownies pretty much make the world go round, right?!

My mother’s favorite desserts are anything with blueberries and my dad’s favorite treats are lemon desserts, especially Lemon Icebox Pie. My mom always did her Lemon Icebox Pie with a vanilla wafer crust instead of the traditional graham cracker crust. It was so good!

As a result of that family favorite, I developed this Lemon Icebox Cake that has a white cake as the base, topped with that same luscious lemon filling and whipped cream as an icing.

This dessert recipe is easy to make, tasty, and great for potluck parties especially during the hot weather months!

Additionally, it’s better when made 1 or 2 days before serving. The flavors melt together and the cake becomes moist from the filling. For this reason, it’s a great dessert for entertaining.

Lemon Icebox Cake

  1. You can make a scratch-made cake instead of using the cake mix if you prefer. Proceed with the filling and topping as directed in the recipe instructions.
  2. The citric acid in the lemon juice reacts with the sweetened condensed milk and thickens it without cooking. After whisking about 30 seconds, you’ll see the mixture begin to thicken. After refrigerating, it will thicken even more and will hold up the whipped topping.

  1. My cake was also soupy in the middle but the top is browning so I can’t leave it in there much longer. Is it because I used a round spring foam pan instead of a 9×13 dish?

  2. Excellent receipe. I followed exact instructions only making one small adjustment. I added one and a half tablespoons of lemon extract to the sweetened condensed milk and lemon juice filling mixture. Cake was delicious reminded me of my Grandma’s lemon meringue pie,minus the pie crust and meringue topping. Thank you receipe brought back alot of good memories for myself and my family. I will definitely be passing this recipe along to my two daughters. Thanks for the recipe!!!!

  3. If I make this a day ahead, should I wait to put the whip cream on the day of? Thanks!

  4. HELP!
    My cake was still very soupy in the middle and collapsed while cooling, creating a concave cake. Is this normal or a fail?

  5. I am going to HAVE to make this! I will take lemon over any other flavor. I am not a fan of boxed mixes, do you have a scratch cake recipe you recommend for this dessert? Thanks for all your yummy recipes!!!!

  6. 5 stars
    How long will this cake last in the refrigerator after cutting? It looks really good Paula.

  7. This sounds refreshing. I can just imagine this on a warm day. Thanks for sharing, Paula.

    Wishes for tasty dishes,
