Recipe Information
Ingredients
- 1 cup Unsalted butter, softened
- 4 cups Powdered sugar (confectioners' sugar)
- 3 tablespoons Key lime juice, freshly squeezed
- 2 teaspoons Key lime zest
- 1 teaspoon Vanilla extract
- 2 tablespoons Heavy cream (optional, for consistency adjustment)
- 1 pinch Salt
Instructions
In the bowl of a stand mixer or a large mixing bowl, add softened unsalted butter. Using a stand mixer fitted with the paddle attachment or a hand mixer, beat the butter on medium-high speed for 3-4 minutes until it is light, fluffy, and creamy.
Reduce the mixer speed to low and gradually add the powdered sugar, one cup at a time. Beat well after each addition to ensure the sugar is fully incorporated before adding more. Scrape down the sides of the bowl as needed.
Once all the powdered sugar is incorporated, add the freshly squeezed key lime juice, key lime zest, vanilla extract, and a pinch of salt to the mixture.
Increase the mixer speed to medium-high and beat for another 2-3 minutes until the frosting is light, smooth, and fluffy. If the frosting is too thick, add heavy cream one tablespoon at a time and mix until the desired consistency is achieved.
Taste the frosting and adjust the flavor as needed by adding more key lime juice or zest for extra tanginess.
Once the frosting is ready, use it immediately to frost cakes, cupcakes, or other baked goods. Alternatively, store it in an airtight container in the refrigerator for up to one week. Bring it to room temperature and re-whip before using if needed.
