Blend 3 teaspoons of vanilla extract with instant coffee in a bowl; let them mingle for 15 minutes.
Throw slightly softened butter into the coffee-vanilla blend. Mix them for 1-2 minutes at medium speed. Scrape down the sides of the bowl with a spatula.
Pour in 1.5 pounds or 6 cups of powdered sugar. Cover the mixer with a towel to keep it tidy.
Set the mixer to low for about 30 seconds, then increase to medium-high for 30 to 45 seconds. Taste test and adjust with vanilla or milk as needed.
