Mix all of the ingredients together using a hand mixer or Kitchen Aid. Roll in very small balls – about 1/2 inch. Dip in sugar and place on a baking sheet with parchment paper. Take your thumb and press down in the center of each ball to create a place for the chocolate kisses. Bake at 375 for 10-12 minutes. Let the cookies cook before you place the chocolate kisses on them – otherwise the chocolate will melt.
