I found this recipe for recently. Antalya and I tried making them several weeks ago. They were so easy and turned out delicious. I couldn't stop munching on them. You could put frosting on them like sugar cookies, or just eat them plain like they do in England (this is the same recipe I used to make Antalya's birthday pizza cookie).
1/2 c soft butter
1 1/4 c sugar
1 1/2 c flour
Pinch of salt
Beat butter and sugar together. Add egg and beat well. Add flour and salt and mix until it forms a ball of dough. Add more flour if needed. Roll out and cut into desired shapes. Bake on greased cookie sheet at 375 for 7-10 minutes (only just golden around the edges).
