The key to this frosting is beating the butter for five full minutes.

Once the butter is whipped, add the cream cheese.

Add the vanilla paste. If I want a serious vanilla taste, I'll add more vanilla paste.

Add salt.

Add heavy cream, if needed. If you are going to pipe scoop out with large spoon, hold sideways over bowl. Frosting should plop back into bowl in about a second or two. If it doesn't you will need to add a little heavy cream.
