Creating Cherry Jam Thumbprint Cookies is a straightforward process that even novice bakers can master. Follow these steps for perfect cookies every time:

1. Preheat Your Oven: Start by preheating your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats for easy cleanup.
2. Cream the Butter and Sugar: In a large mixing bowl, use an electric mixer to beat the softened butter and granulated sugar together until light and fluffy. This should take about 3-4 minutes.
3. Add Egg Yolks and Vanilla: Add the egg yolks and vanilla extract to the butter mixture. Continue to mix until well combined.
4. Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Avoid overmixing, as this can make the cookies tough.
5. Shape the Dough: Using a tablespoon or a small cookie scoop, form the dough into 1-inch balls. Place the balls on the prepared baking sheets, leaving about 2 inches of space between each cookie.
6. Create the Thumbprint: Using your thumb or the back of a small spoon, gently press an indentation into the center of each cookie ball. Be careful not to press too hard, as you don’t want to break the dough.
7. Fill with Cherry Jam: Spoon about 1/2 teaspoon of cherry jam into each indentation. Be careful not to overfill, as the jam will spread slightly during baking.
8. Bake the Cookies: Bake the cookies in the preheated oven for 12-15 minutes, or until the edges are lightly golden. It’s important not to overbake, as the cookies will continue to firm up as they cool.
9. Cool and Dust: Allow the cookies to cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely. If desired, dust with powdered sugar before serving.
