Yum! Thumbprint are quite possibly my favorite Christmas cookie. I should make them more often!
Ingredients:
1 cup (2 sticks) unsalted butter, softened
2/3 cup granulated sugar
2 egg yolks from large eggs
1 teaspoon vanilla extract
2 cups all-purpose flour
roughly 5 tablespoons fruit jam (I chose blackberry)
Instructions:
Preheat oven to 375 degrees. Line baking sheet with parchment paper.
In large bowl, beat together butter and sugar until light and fluffy, about 2-3 minutes. Beat in yolks and vanilla. Gradually add flour and salt. Mix until well-blended.
Roll dough into small balls 1 inch in diameter. Place on prepared baking sheet. Indent each ball with your thumb or the back of a small spoon.
Bake 8-10 minutes or until cookies are set and bottoms are just barely golden brown. If needed, reinforce cookies’ indents. Carefully spoon about 1/2 teaspoonful of jam in the center of each cookie.
Bake for 3-4 more minutes until edges of the cookie are slightly golden and the jam melts in the middle. Transfer cookies to cooling rack.
Yield: about 40 small cookies
*If you plan on freezing these cookies for a later date, place them in a box (one of those gift boxes for clothes from a department store, a shoe box, or any other sturdy box) and place wax paper between the layers so the jam will not stick.
