This recipe was given to me by Cathy Warner. This is her mother's, Clara Zilch, recipe, as well as her great- grandmother's. The most unusual thing about this recipe is that it contains 6 hard-boiled egg yolks, but no one will notice. You can use your favorite jam to fill the butter cookies.
6 hard boiled egg yolks only (eat the whites), cooled
1 3/4 cups flour sifted
1 1/4 cups butter, room temperature
2/3 cup confectioners sugar
jar of your favorite jam for filling cookies
additional confectioners sugar for dusting cookies
Hard boil the eggs, shell, and allow to cool. In a small bowl, use a fork to finely crumble the yolks. You may eat or discard the egg whites.
In a medium-size bowl, combine the flour, butter, and confectioners sugar. Roll out dough on a lightly floured surface to 1/4-inch, not too thin or the cookies will be crispy and crumbly. Use a small round cookie cutter. Remove circles with a spatula or knife and place on an ungreased cookie sheet. Bake in 300 degree oven for 15 to 18 minutes, or until lightly browned on bottom. Cool cookies. Spread a little of your favorite jam on cookie halves and sandwich together. Sprinkle both sides of cookies with confectioners sugar. Store in a container.
This recipe makes about 3 dozen cookies, depending on the size of the cookie cutter.
