Thumbprint Cookies (Stalker Family)

Step 1: Preheat oven to 350 degrees F (177 degrees C) and place rack in center of oven. Line a baking sheet with parchment paper.

Step 2: In the bowl of your electric mixer (or with a hand mixer), cream the butter and sugar until light and fluffy (2-3 minutes). Add the egg yolk and vanilla extract and beat until combined.

Step 3: In a separate bowl, whisk together the flour and salt. Add the flour mixture to the batter and beat just until combined. If the batter is too soft to roll into balls, refrigerate for about 30 minutes.

Step 4: Place on the prepared baking sheet spacing about 1 inch (2.54 cm) apart. Using your thumb or end of a wooden spoon, make a indentation into the center of each cookie and fill with about 1/4 - 1/2 teaspoon of jam.

Step 5: Bake for about 13-15 minutes, or until cookies are set and the nuts have nicely browned. Remove from oven and place on wire rack to cool.

Step 6: Makes about 20 cookies.
