How to Make Cookies with Hard Boiled Eggs

According to Sarah Fogle cooked egg yolks are an old school baking trick that make a pastry light, but soft and dense - which is how it still makes its way into a family favorite.  This recipe is basically a dressed up sugar cookie, handed down from her grandmother with relatively few ingredients. It has a buttery, crumbly flavor that isn't too sweet to decorate with icing or sprinkles, which makes it pleasing for adults and kids alike.  Also goes great with a glass of cold milk.

Ingredients:

4 cups of flour
2 cups of sugar
4 teaspoons baking powder
2 teaspoons vanilla extract
1/2 lb (two sticks) butter, softened
4 hard boiled egg yolks, sifted
4 whole eggs
Optional toppings: icing, sprinkles or egg wash

Directions:

1. Prepare egg yolks: Hard boil 4 eggs and separate the yolk. Press the yolks through a sieve to get a crumbly mix.
2. Make the cookie dough: Mix together sugar, flour, baking powder, hard boil egg yolks and butter in a large mixing bowl. Add 4 whole eggs and vanilla. Makes a stiff dough.
3. Chill and set aside: Wrap dough in plastic wrap and chill for about a ½ hour.
4. Roll and bake: Use a small amount of flour on a cutting board to roll out dough with a rolling pin. Cut into favorite shapes. Bake at 350 degrees until the edges are brown (about 12 minutes).
