Unpopular opinion- I'm not a fan of buttercream frosting or any frosting really because they're usually too sweet. That being said, I'm always looking for a light frosting with the perfect amount of sweetness. When baking, I try to shy away from buttercream and stick with whipped cream frostings, but I finally decided to make a classic vanilla buttercream frosting. I was not disappointed, it's a simple and classic frosting (made not too sweet), perfect for any dessert.
1 1/2 cups butter, softened
1/4 teaspoon salt
2 cups powdered sugar, sifted
1/8-1/4 cup milk
1 teaspoon vanilla
In a large bowl, cream the butter and salt until light and fluffy.
Gradually add the powdered sugar to the bowl, mixing until fully incorporated.
Add the milk and vanilla to the bowl, mixing until combined. The frosting should be a fluffy, smooth consistency.
Heavy cream or whipping cream can also be used instead of milk. The milk/cream thins out the buttercream and can balance the sweetness, base how much milk/cream to add on consistency and sweetness.
While making the buttercream, scrape the sides of the bowl to prevent clumps of butter in your frosting and ensure an even consistency.
If making the buttercream in advance, store the frosting in the fridge covered. When ready to use, take the frosting out of the fridge and allow it to become room temperature, add another few tablespoons of milk, and mix until combined and the consistency is fluffy.
