1/2 lb. sweet butter
1 egg yolk
1 tbsp. sugar
1 jigger cognac or brandy or 1 tsp. vanilla
1/2 tsp. baking powder mixed in with part of flour
2 1/2 to 2 3/4 c. flour
3/4 c. chopped walnuts or 3/4 c. chopped almonds, blanched or toasted

Cream butter well until fluffy. Add sugar, beat in well. Add egg yolk, beat in well. Add walnuts or almonds and flavoring. Add flour with baking powder. Add rest of flour slowly until you can shape dough into crescents without cracking.

Oven at 350 degrees. Bake until sand colored, approximately 30 minutes. Have tray or pan ready with a layer of powdered confectioners' sugar. Put crescents on sugar while hot. Sift more sugar on them. Allow to stand until cool.
