Step 1

Using a whip attachment with a standing mixer or hand held mixer with a large bowl, whip softened butter on high about 5-10 minutes until very pale and light and fluffy. It should double or triple in size. Scrape down the sides of the bowl with a rubber spatula as needed to ensure all the butter is whipped.

Step 2

Once the butter has been whipped, slowly add the sweetened condensed milk in 3 or 4 additions, mixing in between each addition, scraping down the bowl with a spatula as needed.

Step 3

If the buttercream looks separated or curdled, place in the fridge for 15-20 minutes and then re-whip. It should come back together to a smooth frosting.

Step 4

Mix in optional vanilla and salt and it’s ready to use on your favorite cakes and cupcakes.
