1 1/2 cups flour
1/4 teaspoon salt
1/2 cup butter or margarine
3 tablespoons water
1 teaspoon vanilla
Mix the following ingredients thoroughly: 1/4 cup butter or margarine, 1 egg yolk, 1/2 cup sugar, 1 tsp vanilla, 1/4 cup cocoa and 1/2 cup finely chopped nuts or flaked coconut.
Heat oven to 350. Mix flour and salt. Cut in butter. Sprinkle with water and vanilla. Mix well with fork. Using 1/2 of dough at a time, roll out 1/16″ thick on cloth-covered board generously sprinkled with sugar. Cut in 2 1/2″ squares. Spread 1 level tsp filling in center of each square. Bring corners to center. Seal together. Place sealed side up or down on ungreased baking sheet. Bake 15 to 20 minutes. Makes about 2 1/2 dozen.
Preheat oven to 350 F. Line baking sheets with parchment paper or a non-stick baking mat. In a large bowl, beat together butter and sugar until light and fluffy. Beat in egg yolks, vanilla extract and salt. Gradually stir in flour. Form dough into 1-inch diameter balls. Dip in lightly beaten egg whites, then roll in nuts. Place 1 inch apart on prepared cookie sheets. Press down center of each with thumb. Bake for 16 to 18 minutes, or until golden brown. Cool on baking sheet for 5 minutes, then remove to a wire rack to cool completely. Just before serving, fill centers of cookies with jam. Or, fill centers with 1/2 teaspoon of jam before baking.
