Learn how to make my Best Vanilla Buttercream Frosting Recipe, with my chef-tested tips for the perfect Buttercream Icing!
In a stand mixer fitted with the whisk attachment (or using an electric hand mixer) whip the butter until light and creamy for about 7 - 8 minutes on High speed.
While the butter is whipping sieve the powdered sugar about 3 times to remove lumps and incorporate air.
Once the butter is pale in color and light slowly add in the sifted icing sugar one spoon at a time at Medium-High speed. Let the sugar fully incorporate before adding in more.
Add the milk and vanilla extract and whip on High speed for another 3-4 minutes until very light, creamy, and fluffy.
Use the buttercream straight away or keep it refrigerated for up to 10 days. Before use, make sure it comes to room temperature. It also can be frozen for up to 4 weeks.
