This key lime frosting is refreshing and easy. It only takes 10 minutes to prepare and can be doubled if you love lots of frosting.

Key Lime Buttercream Frosting

butter, softened

lime

vanilla extract

salt

sugar

Key lime juice

Tbsp. milk

Beat first 4 ingredients at medium speed with an electric mixer until creamy.


Gradually add powdered sugar alternately with Key lime juice, 1 Tbsp. at a time, and 1 Tbsp. milk, beating at low speed until blended and smooth after each addition. Beat in up to 1 Tbsp. additional milk for desired consistency.


Frosting looks as yellow as the butter used.  Not sure how to make it white and fluffy as in pic.Melts super fast within minutes...looking like melted butter again... :-(Anybody has advice? If not, I've to switch back to my old trusty recipes again....

Truly delicious, but the consistency was too soft for me as written. The filling squeezed out the side of my cake. I recommend forgoing the 1T of milk, or if you do add it, be prepared to add more powdered sugar to thicken it back up.

I have not made this yet. What would be a good cake batter recipe to go with this frosting?? Looks good for this coming Easter weekend.

Having never made frosting before this recipe was simply amazing and no fuss. Truly delish and used it on a carrot cake. Brilliant :)

This frosting is wonderful.  I had more than enough to thickly frost 24 cupcakes.  Going to use this same recipe but try different flavors than lime next time.

This was truly outstanding!!  I substituted regular lime zest and fresh lime juice, otherwise made it just as it is written.   It got lots of raves at the gathering.  I used it for white wedding cake cupcakes....yummy!  Also lots of requests for the recipe...You won't be disappointed if you try it.  The name should be "SPOON worthy"  as we had to control ourselves from sampling and sampling  it off the spoon ...lol  I also agree with the review about the cream cheese and the hot weather...this will melt if out of the fridge too long!

Terrific quick recipes - great for a summer treat. You can also make this as a Cream Cheese Icing by reducing the butter to 1/2 stick and adding an 8 oz. block of softened cream cheese, beaten with the butter. The cream cheese version is good when you need a slightly sturdier icing to stand up better to hot weather, as the Buttercream version can't be without refrigeration for very long or it will run.

This icing is fantastic... but make sure you double it- you won't need all of it, but one recipe isn't enough to cover the entire cake.  You'll need 1 1/2 times the icing.. it's wonderful on the basic vanilla cake recipe.

This frosting is a PERFECT 10. My family loved it including my children. It is the perfect combination of sweet and tart. It really cuts down on the sweetness of the standard vanilla buttercream. I used one recipe on a bundt shaped cake and had plenty of frosting and even had some left over which everyone fought for. But I do think if I was doing a layer cake it wouldn't have been quite enough and I would double it. If you like lime, you've got to try this recipe.

This is much easier to make then you would think and everyone loved it--all the adults at least.  I doubled the recipe because its not enough for one cake.  I also put a little tiny bit of almond extract to balance the tartness.

I used a lemon curd for the filing between layers.  I would definitely make this again.
