Step 1

Place the butter in the bowl of a stand mixer. With a whisk attachment, whip the butter until it's creamy and white in color - about 3 - 5 minutes on high speed (not maximum speed).

Step 2

Add the salt, cream and vanilla, and whisk further until the butter-cream mix is light and fluffy (for a few minutes).

Step 3

Lower the speed and add 8 oz of the confectioner's sugar - a little at a time, and incorporate all the sugar into the butter. Make sure to scrape the sides as you go.

Step 4

Once the sugar is incorporated into the butter, increase the speed and whisk on high for 1 minute. Taste and add the rest of the confectioner's sugar if needed. Whisk for a further 2 - 3 minutes until you have a light, fluffy, soft, spreadable frosting.

Step 5

If the frosting is too stiff, you can add extra cream (1 tbsp at a time) to get an even softer buttercream.
