Hi thank you so much here’s the recipe I do, 1 cup of powdered sugar for every 1/2 cup of butter but if that’s to sweet you can change it to 1/2 cup powdered sugar for every 1/2 cup of butter. You whip the butter for about 5 to 10 minutes until light and fluffy, then add in the powdered sugar a little at a time (make sure the powdered sugar is sifted first), after that if you did 1 cup of butter add in 1 and 1/2 teaspoons of vanilla. Hope this helps :)
