In a large mixing bowl, combine the softened cream cheese and unsalted butter.
Using an electric mixer, beat the cream cheese and butter on medium speed until smooth and creamy, about 2-3 minutes.
Gradually add the powdered sugar, one cup at a time, beating on low speed after each addition to avoid powdered sugar clouds. Scrape down the sides of the bowl as needed.
Once all the powdered sugar is incorporated, increase the mixer speed to medium-high and beat for 2-3 minutes until fluffy.
Add the freshly squeezed key lime juice, key lime zest, vanilla extract, and a pinch of salt to the bowl.
Beat the mixture on low speed until the ingredients are fully combined, then increase to medium-high speed and mix for an additional 1-2 minutes to ensure a light and creamy texture.
Taste the frosting and adjust the key lime juice, zest, or powdered sugar as desired to achieve your preferred balance of tanginess and sweetness.
Use immediately to frost your favorite baked goods, or store in the refrigerator in an airtight container for up to 5 days.
