Easy Key Lime Pie Cake Recipe 

When I was a kid, I wasn’t necessarily a fan of lime-flavored anything. As time is going on, though, I’ve become more accustomed to the flavor of key lime, and I honestly cannot get enough of it. I make all sorts of key lime recipes, including this easy key lime cake.

The entire family actually loves the flavor too. So I’m more than happy to make it for all of us whenever somebody gets a craving. Or I will take it to parties and events when I want something extra special and not just a typical boring dessert.

The biggest thing that sets this dessert apart from other lime recipes is that it has lemon and lime. Using lemon cake with the addition of the key limes takes it to the next level of excellence. I seriously can’t wait for you to taste it. 

What If I Can’t Find Lemon Cake Mix 

Don’t worry! If you can’t find a lemon cake mix, that is more than fine. You can easily swap it out for a white cake, yellow cake, or french vanilla cake. Or if you combine any other fruit-flavored cakes, they would work well too.

The lime cake may not have as an intense citrus flavor if you don’t use a lemon cake mix; however, it’s still going to be divine, and you’re going to love the taste.

Another option would be to use your favorite lemon cake recipe that’s homemade. Using a homemade cake would be a fantastic idea, an easy solution to not being able to buy a lemon cake mix. 

How to Store Cake 

The easiest way to store this cake is to keep it in an airtight container in the refrigerator. First of all, it tastes really good cold. Secondly, due to the cream cheese and the icing, it just ages better if you keep it chilled.

Can You Freeze This Cake 

Yes, you can freeze this lemon-lime cake. You will need to wrap it up tightly and freeze it for up to three months. When you’re ready to serve, it merely thaw it out in the refrigerator overnight. Then indulge in this fantastic key lime pie cake. 

Variations to Recipe 

  • Sprinkle some toasted coconut on top of the icing for an extra fun flavor.
  • Add slices of key lime over the top of the frosted cake. It will look gorgeous and add a vibrant green color. 
  • Consider using a strawberry cake mix with the other ingredients to have even more fun and playful dessert idea. Limes and strawberries go so amazing together; you’ll be impressed by how wonderful it tastes.
  • You could also add orange zest or orange slices to the cake to give it even more citrus flavor. Plus, it will add a pop of color.
