Jam-Filled Butter Cookies

Ingredients

• 3/4 cup butter, softened
• 1/2 cup white sugar
• 2 egg yolks
• 1 teaspoon vanilla extract
• 1 3/4 cups all-purpose flour
• 1/2 cup fruit preserves, any flavor

Directions

1. Preheat the oven to 375 degrees Fahrenheit.
2. In a medium bowl, cream together the butter, white sugar, egg yolks and vanilla extract. Mix in flour a little bit at a time until a soft dough forms. Roll dough into 1-inch balls. If dough is too soft, refrigerate for 15 to 20 minutes. Place balls 2 inches apart onto ungreased cookie sheets. Use your finger or an instrument of similar size to make a well in the center of each cookie. Fill the holes with the preserves.
3. Bake for 8 to 10 minutes in the preheated oven, until golden brown on the bottom. Remove from cookie sheets to cool on wire racks.
