I use a basic cream cheese frosting for my sugar cookies
4 T Butter
1 Cream cheese block 8 oz
2 T Milk
3 1/2 Cups Powdered Sugar
1/2 tsp vanilla
Put all ingredients in bowl and beat until smooth consistency. If the frosting is not thick enough just add more powdered sugar and if too thick then add a little more milk. Simply delicious on sugar cookies.
