KEY LIME CAKE

This delicious Key Lime Cake recipe features moist lime cake layers with tangy lime and cream cheese frosting. Made with lime jello mix for vibrant color and maximum lime flavor. Only takes 10 ingredients you likely have on hand! An easy from scratch cake with a refreshingly bright citrus taste that’s perfect for summer parties, birthdays, or anytime you crave a lime dessert. Store in the fridge after frosting for up to 5 days.

Can I use regular limes instead of key limes?

Yes, you can substitute regular Persian limes if key limes are unavailable. The flavor will still be delicious.

Do I need to use jello mix or can I leave it out?

The lime jello mix helps give the cake that signature green color and enhances the lime flavor. But in a pinch, you can leave it out – the cake will still taste great!

Can I make this into a sheet cake instead?

Absolutely! Just pour the batter into a greased and floured sheet cake pan. It will likely need 5-10 extra minutes of bake time since it will be spread thinner.

What kind of frosting can I use if I don’t like cream cheese?

Whipped cream or a lime buttercream frosting would also be delicious on top of this cake.

For Frosting:

Tips:

  • Be sure your ingredients are at room temperature for best texture and rise.
  • Zest your limes before juicing to add even more lime punch!
  • For a 3-layer cake, split the batter between 3 greased and floured round cake pans.
  • Garnish with lime zest or slices for a pretty presentation.
  • Store frosted cake covered in the fridge for up to 5 days. Freeze unfrosted cake layers for longer storage.
  • Substitute lemon for the lime if desired for a lemon cake variation.
