Another Pinterest find, but every baker needs to have some of this in their cupboards!
I use my magic bullet to whip it up, but you could probably use a whisk and do it by hand or use a mixer.
It is all equal parts... Vegetable Oil, Crisco, and Flour. Whip Whip Whip until it is smooth!
You can use this on anything. It works wonder in muffin tins! Use a pastry brush or even just a paper towel to brush it on! Bake and release! :)
