1 cup soft butter
1 cup sugar
2/3 cup warm (not hot) cream or milk
2 tsp vanilla extract
a dash of salt
Whip butter and sugar in a large bowl, until light, on high speed. Continuing on high speed, slowly add cream or milk, vanilla and salt(put into milk). Whip at least 5 minutes until the consistancy of whipped cream.
It may seem runny, but be patient- it will work!
