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.

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 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.

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 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!
