Instructions
Using an electric mixer with the whisk attachment, beat the cream until it's very stiff then add the vanilla and mix it through.
Change over to the paddle attachment and keep beating until the butter forms. It will turn yellow and separate from the buttermilk.
Pat the butter between your two hands or two paddles until the liquid has been released then pat dry with a cloth. Strain the buttermilk into a separate container and refrigerate.
