1 cup finely chopped walnuts
1/3 lb. soft butter, half sweet and half salt
1/4 cup sugar
1 cup flour
2 tsp. vanilla
Lightly toast the walnuts in a low oven and then let cool. Finely grind the walnuts in a food processor. Cream the soft butter and sugar together. Add the walnuts, flour and vanilla and mix well.
With a plain piping tip, pipe the cookie dough in drops onto a buttered and floured pan or onto parchment paper. Bake in preheated 300° F. oven for 20--30 minutes, or until pale brown in color. When cool, sprinkle powdered sugar over the cookies. Store in an airtight container. The cookie dough freezes well.
