3-4 cups powdered sugar sifted
½ cup cocoa powder, sifted
1 teaspoon vanilla extract
3-5 tablespoons milk or cream
In a large bowl, beat the butter until fluffy and no lumps remain.
Turn the mixer to low and beat in 2 cups of the powdered sugar. Once combined, beat on medium-high for 15 seconds.
With the mixer on low speed, carefully beat in the sifted cocoa powder, vanilla, and salt.
Then beat in the rest of the powdered sugar about ½ cup at a time, alternating with 1-2 tablespoons of milk/whipping cream until the desired consistency and sweetness is reached. If the frosting is too thick, add in a little extra milk/cream. If it's too thin, add in a little more powdered sugar.
Once everything is combined, beat on medium-high speed for 15 seconds.
