Ciao to all! I have a great recipe for buttercream frosting that i throw together by sight (my mom's talent)but i am putting too much or too little of something in....it looks gritty sometimes and other times it starts melting as i try to ice it...even when i stick the frosting in the fridge first to harden then ice the cake, it gets warm and then melts. please any advice would be great! i put in one stick of butter, softened, one box of confectioner's sugar, milk drops by sight and vanilla by sight/taste.
thanks y'all in advance!

if it's gritty you probably need to beat it longer or if it's big lumps then you may need to sift your powdered sugar. if it's too soft you need more powdered sugar.

You may have let your butter soften too much. Try putting your vanilla before the milk. That way it will be flavored first and you won't have to add more liquid to something that is the right consistency.
