    This is my go to frosting. In no way does it ever taste like grocery store frosting. If I ever go back to the crisco butter Wilton recipe people get mad at me! In fact, I am making a baby shower cake tonight with it.

    If you want to spend a good amount of time, effort and money making something that tastes EXACTLY like the grocery store cake frosting, make this. I was horrified at the way it tasted, and super disappointed. Maybe with salted butter, it would taste better. I'm never going to try it.

    Amazing texture and flavor. I made it with salted butter because I prefer salty undertones. Very yummy!
