Creating your batch of Shortbread Jam Thumbprint Cookies is straightforward if you follow these easy steps:

1. Preheat Oven: Start by preheating your oven to 350°F (175°C). Prepare a baking sheet by lining it with parchment paper.
2. Cream Butter and Sugar: In a mixing bowl, beat the softened butter and granulated sugar together until light and fluffy, which usually takes about 2-3 minutes.
3. Add Vanilla: Mix in the vanilla extract until well combined.
4. Combine Dry Ingredients: In a separate bowl, whisk together the flour and salt.
5. Mix Together: Gradually add the dry ingredients to the butter mixture, stirring until fully combined. The dough should be soft but not sticky.
6. Shape Cookies: Take about a tablespoon of dough and roll it into a ball. Place the ball on the prepared baking sheet. Repeat for the rest of the dough.
7. Make Thumbprints: Use your thumb (or the end of a wooden spoon) to create an indentation in the center of each ball.
8. Fill with Jam: Spoon a small amount of jam into each indentation, being careful not to overfill.
9. Bake: Place the baking sheet in the oven and bake for 12-15 minutes or until the edges are lightly golden.
10. Cool: Once baked, remove the cookies from the oven and let them cool on the baking sheet for about 10 minutes before transferring them to a wire rack to cool completely.
11. Dust with Sugar: If desired, dust the cooled cookies with powdered sugar for a sweet finishing touch.
