Key Lime Cream Cheese Frosting Recipe (1)

Key Lime Pie is one of my most favorite desserts and cream cheese frosting... well, it goes on anything! So by combining those flavors into one frosting recipe - I hit it out of the ballpark. I really didn't even need a cupcake to eat it on... I could eat the frosting with a spoon!

I've used this frosting on cupcakes, a layer cake, and bundt cakes. I love that it's even stiff enough that you can use it for cakes where you want to pipe a pretty border!

Are key limes different from other limes?

Yes. The most obvious difference is that key Limes are smaller, darker green, and have thinner skin. But that's not what's important when using key limes in recipes. For recipes, key lime juice is more potent and the flavor is more floral. The juice is tart and less acidic than regular lime juice.

Can you use regular limes or lime juice in this recipe? Yes. You likely will not notice the difference, but if you can get key limes, do. Or use this amazing key lime juice and skip the zest.

Cream Cheese Frosting FAQ

Can you change the color of key lime cream cheese frosting? Yes! The lime juice only adds the tiniest hint of color so you can add gel coloring to make it any color you want. Or you can add a little green gel color if you want a distinct green to the frosting to "match" the key lime flavor.

How can you stiffen the cream cheese frosting? Add more powdered sugar. To be really careful, you can add the powdered sugar a tablespoon at a time. But I often add more (up to half a cup) at a time to stiffen my frosting.

Is cream cheese frosting or regular buttercream sweeter? The tanginess of the cream cheese plus the lime definitely gives this frosting a less sweet taste than regular vanilla buttercream.
