Here's another recipe from John Cage, this one maybe from a stay in Ithaca? Before he went vegan, obviously. From Empty words: writings '73-'78, p. 91:
Holiday Inn: Room 135.Makes enough for one dance company, I guess.
Four cups of ground walnuts;
4 cups of flour;
12 tablespoons of sugar;
2 2/3 cups of butter;
4 teaspoons of vanilla.
Form into circa 125 small balls.
Bake at 350 degrees in motel oven.
Now back to Room 135.
Roll in 1 pound of powdered sugar.
