Key Lime Cream Cheese Frosting

4 oz cream cheese, at room temperature
1 1/2 cups confectioners’ sugar
1 tablespoon key lime juice
food coloring, optional

In a large bowl, beat together all ingredients until well blended. Frost on cooled cupcakes or cake.

icing for about 12 cupcakes or a single layer cake.

My thoughts:

I still find a few things about key limes amazing. The first thing is that they have become really easy to find in the last couple of years. Secondly, even here in Maryland, far from any place they could possibly grow, they are often cheaper than regular limes. finally, they produce a lot of juice. I got a whole tablespoon of juice from a lime the size of a quarter. This icing has the whole sweet-tart thing going. It’s good with other citrus flavors or paired with something more tropical like mango or pineapple. It would probably be good on vanilla or chocolate cupcakes/cake as well.


  1. You had me a Key Lime! That looks amazing!

  2. Just lovely, the color is so fresh. What kind of cupcake would this taste good with?

  3. Hey Kim: I just posted what I paired it with: mango chile cupcakes.

  4. Hi Rachel..
    You have a cutesy Blog, I like it. This recipe caught my eye because I have just created a mango cake and cupcake reciepe due to my husband’s love for mango!!
    I am new to this blogging thing, so I am stopping by certain blogs that catch my eye to say Hello fellow baker:)

  5. Mmmm. I am thinking that this would be good piped into the middle of coconut cupcake.

  6. Hi Rachel-
    My timing is just a touch off today. Caught your new post, love the idea. Dare I say, I am gaining wait too fast with all this good food around me!

  7. I love your blog – I check it every time I’m at work and have almost filled a booklet with things to try from here. One question, though – do you have any suggestions for picky eaters that don’t love cream cheese? I can’t wait to make a key lime icing, but my boyfriend and I aren’t big fans of cream cheese, so I’m hoping there’s an alternative. Thanks!!

  8. Kristin:
    Kristen: Thanks for the compliment! If I didn’t like cream cheese I’d make a basic butter cream and replace any vanilla with key lime juice.

  9. I’m a huge fan of key lime. This is going on my “must try” list. Very creative!

  10. Wow, I’m jealous! When I lived in Baltimore, I was a student at UMBC and had no way to get to a grocery store. Now, living in Iowa, you definitely cannot find Key limes in the grocery store. I’ve been to Key West four or five times (have family there) so they only time I get key limes is on those few-and-far-between vacations.

  11. would this be good on a fruit pizza?

  12. Anon-I have no idea. Try it and let me know!

  13. I'm making this tomorrow. I think I'll try to shoot it, but I don't think it will be as pretty as your picture!

  14. Just tried this recipe 🙂 Fan-freakin'-tastic!!! I doubled the recipe for what i was making– and added 4 tablespoons (up from 2) of key lime juice. Thanks for the good work!!
