In an electric mixer with the paddle attachment beat the butter and cream cheese until smooth and creamy. Add the 2 tablespoons of sugar, a pinch of salt, and vanilla. Mix until just blended. Slowly add the flour to the mixer while on low speed.
Scrape sides with a rubber spatula as needed.
Mix until just combined, but do not over beat. Remove dough from mixer and place on a well-floured board. Knead dough about 30 seconds until a uniform ball is achieved. Divide into 3 equal parts. As needed, remove each portion of dough from the refrigerator.
