  • Kitchen tools you’ll need: A stand mixer or a hand mixer, large bowl, medium bowl, measuring cups and spoons, a citrus grater, 13 x 9 inch baking dish or pan.
  • What are key limes? Even though Key limes aren’t exclusive to the Florida Keys, characteristically they are quite a bit smaller in size than a regular Persian or Mexican lime and they have a smoother skin and texture.
  • The flavor is also more tart than a Persian lime that’s found most often in the supermarket produce section. It adds a distinct tartness to the overall flavor.
  • The juice of key limes is more yellow than green. In keeping with the color of the skin, I add a few drops of food coloring to the filling. This is for visual appeal, and doesn’t alter the flavor at all.  This is completely optional.
  • Is there a substitute for key lime juice? As discussed, you can use the juice from regular limes or you can use half lime juice and half lemon juice in keeping with the actual flavor of key limes. If you’re unable to find key limes at your local grocery any lime will work well in this recipe.

  1. 5 stars
    My boss asked me to make her a key lime cake for her birthday. I stumbled across this recipe and made one for home before making one for her since I’ve never tasted key lime cake or pie. Wow! Delicious! I’m not a baker and this was simple. Thank you. I’ll be researching more of your recipes

  2. Not only does this look stunning but it tastes even better. Couldn’t be happier to have chosen this lime cake as a surprise for my wife, thanks!

  3. Yum! I love dishes made with real lime juice. Here’s a tip from my time living in Florida –key lime juice is not really green. If you see “Key Lime Pie” that is green, run away????

    1. I know it it’s so funny how visual we are isn’t it? It’s perfectly fine to leave out the food coloring as the taste isn’t effected at all.
