1/2 cup walnuts (I used walnut flour,(=basically: pulverized walnuts) It would probably be even better if the walnut pieces were larger)
1 medium egg (or just use 2 egg whites for crunchier cookies)
2 heaped tablespoons of powdered sweetner (you can add more if you like sweeter cookies)
1 tsp cinnamon
(I added nutmeg as well)
Form little balls and place on parchement paper /baking sheet
Bake for 360 degrees for 10 minutes or until nicely browned.
(I think these would be good made with cocoa powder instead of cinnamon too)
