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
- 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.
- 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.

This recipe is fail-proof and delicious every time! I haven’t needed to alter anything.
My family specifically requests this cake and even our pickiest eaters LOVE IT.
So easy, economical, and tasty – can’t beat it.
Paula says
Thank you so much!!
Mari says
I MADE THIS CAKE AND I HAVE TO SAY, I PREFER IT TO THE ICE BOX CAKES THAT USE COOKIES OR SOME TYPE OF FILLING AS SUCH. THE ONLY THING I WILL DO DIFFERENT IS USING ONE CAN OF CONDENSED MILK INSTEAD OF TWO. I’M NOT A FAN OF A LOT OF SUGAR, THE CAKE WAS WAY TOO SWEET.
Pamela says
I made this cake for my husband’s birthday and it came out great!! This recipe is very easy.
Thank you
MaryLou Plaksin says
I have a couple of questions. Will the cake work with two 8 inch pans? It says it serves 15. Are those large slices? Can I freeze the cake and do the whipping cream later.
I am making this cake for my daughter for an event this weekend and I want it to be perfect. It looks so Yummy.
I look forward to your reply. Mary Lou

Paula says
Yes two 8-inch pans will work. I would freeze the cake but not the lemon layer or whipped cream
Carol Bonsignore-Kitchen says
I’m making it now and the timer went off and it caved in and is soupy in the middle. I made it in a 9×13 What do I do now? I put it back in but it is already browning. YIKES!
Gloria says
This is one of the most delicious cakes I’ve ever tasted or made. My Bunko group loved it and they all wanted the recipe. I plan to take it to a family function next. I know it will be a big hit there too. Thank you!
Paula says
You’re welcome! I’m so happy you like it.
mandy says
so do you keep this refrigerated after the cake is done or is it ok to leave out overnight?
Paula says
It needs to be refrigerated
Alice says
Just found this recipe looks delicious! Do you think it would work as a layered cake?
Paula says
I’m afraid the lemon pudding layer wouldn’t be sturdy enough and the cake would slide to the side.
Myra says
I’ve made this as a layer cake with a few small differences… I bake the cake in two layers but split the layers to make four. In between each layer, I put the filling mixture (condensed milk and lemon juice). After putting the last layer on top, I add whipped cream to what’s left of the filling and spread evenly over top and sides. I’ve never had any issues with it sliding.
Paula says
This sounds wonderful. I’m going to make it your way!!!
JMA says
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?
Paula says
More than likely it is since the batter will be thicker in the springform pan
Diana says
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!!!!
Paula says
I’m so happy you enjoyed it!
Nina says
If I make this a day ahead, should I wait to put the whip cream on the day of? Thanks!
Paula says
Either way, I always put on when I make it and it’s fine the next day.
quinteishia love says
CAN I USE MILK INSTEAD OF WATER
Paula says
yes
CJ says
HELP!
My cake was still very soupy in the middle and collapsed while cooling, creating a concave cake. Is this normal or a fail?
Paula says
NO, it should not have done that. It should spring back to the touch in the center
Lisa Langston says
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!!!!

How long will this cake last in the refrigerator after cutting? It looks really good Paula.
Paula says
Mine has been in the fridge a week and it’s still good.
