Method
- In a large mixing bowl, beat the softened unsalted butter with an electric mixer on medium speed until it is light and fluffy, about 2-3 minutes. Ensure the butter is truly softened but not melted; this is crucial for a smooth frosting.1 cup unsalted butter
- Gradually pour in the entire can of sweetened condensed milk while continuing to beat the butter on low speed. Mix until everything is just combined and the mixture is smooth. Avoid overmixing at this stage.1 14-ounce can sweetened condensed milk
- Add the vanilla extract to the bowl and beat on low speed until it is fully incorporated. You should have a smooth, pourable frosting at this point.2 teaspoons vanilla extract
- If you prefer a thicker, more traditional buttercream-style frosting, gradually add the powdered sugar, 1/2 cup at a time, beating on low speed until each addition is incorporated. Continue adding powdered sugar until you reach your desired consistency. If the frosting becomes too stiff, you can add a tiny splash of milk or cream. If adding powdered sugar, you might also want to add a pinch of salt to balance the sweetness.2-3 cups powdered sugar, Pinch salt
- Once all ingredients are added, beat the frosting on medium-high speed for another 1-2 minutes until it is exceptionally smooth and creamy.
Notes
Store leftover frosting in an airtight container in the refrigerator for up to 5 days. For longer storage, freeze for up to 3 months. Thaw in the refrigerator overnight.
