Note: This recipe is easily doubled if you want. I used whole wheat flour, but you could certainly use all or part all-purpose if you prefer. I wanted them to be a bit heartier, so used whole wheat. Also, frozen butter IS better as they get flakier when the butter is frozen, but I generally do not plan far enough ahead to stick the butter in the freezer so then I make them with butter that is cold from the fridge. I grate it in quickly and they are still amazing that way so don’t decide not to make them because the butter isn’t frozen!
