Raspberry Filled Sugar Cookies

These are easy to make and easy to eat.
One of my simplest and best recipes.
These cookies stay soft and keep well.

Ingredients
1/4 cup unsalted butter, softened
1/2 cup vegetable shortening
1/4 cup white sugar
1/4 cup brown sugar
2 egg yolks
1 3/4 cups all-purpose flour
1/4 teapoon baking soda
1/4 teaspoon baking powder
1/4 teaspoon salt
raspberry preserves

Directions:
Preheat the oven to 375 degrees F.
In a mixing bowl, cream together butter,
sugars and egg yolks.
In a seperate bowl combine
baking soda, powder and flour.
Mix in dry to wet a little
bit at a time until doughy.
Roll dough into 1 inch balls.
Place balls 2 inches apart onto
parchment lined baking sheets.
Use your finger to make a well
in the center of each cookie.
Fill the hole with 1/2 teaspoon preserves.
Bake for 8 minutes in the preheated oven,
or until golden brown on the bottom.
Remove from sheets to cool on wire racks.
