1-First, whip the room temperature unsalted butter on medium-high speed with a whisk attachment for 5-7 minutes until it lightens in color and gets super fluffy. I learned the hard way that under-whipping can leave it dense, so give it that full time! Next, add the vanilla extract and fine salt, mixing on low speed just until combined to keep everything smooth.

2-Slowly pour in the sweetened condensed milk in four separate additions, mixing at medium speed after each one; don’t forget to scrape down the bowl to mix everything evenly.

3-If the frosting looks separated or too soft, mix in powdered sugar a half cup at a time until it firms up.

4-Once done, use it right away on your cakes, cupcakes, or cookies for the best results it’s that straightforward!
