Preparation Steps

• Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
• In a large bowl, cream together the softened butter and granulated sugar until light and fluffy.
• Beat in the egg and vanilla extract until well combined.
• In a separate bowl, whisk together the flour and salt.
• Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
• Roll the dough into 1-inch balls and place them on the prepared baking sheets, about 2 inches apart.
• Using your thumb or the back of a small spoon, make an indentation in the center of each cookie.
• Fill each indentation with about 1/2 teaspoon of jam or preserves.
• Bake for 10-14 minutes, or until the edges are lightly golden brown. The centers may look slightly soft.
• Let the cookies cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely.
