Creating the perfect Thumbprint Cookies can be a delightful experience. Here’s a step-by-step guide to help you achieve cookie perfection:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
2. Cream the Butter and Sugar: In a large mixing bowl, beat the softened butter and granulated sugar until light and fluffy.
3. Add Ingredients: Mix in the vanilla extract and salt, ensuring everything is well combined.
4. Combine Flours: Gradually add both the all-purpose flour and almond flour to the butter mixture, stirring until a dough forms.
5. Chill the Dough: Cover the dough with plastic wrap and chill it in the refrigerator for 30 minutes to firm up.
6. Shape the Cookies: Once chilled, scoop about a tablespoon of dough and roll it into a ball. Place the balls on the prepared baking sheet, leaving enough space between them.
7. Create Indentations: Use your thumb or the back of a small spoon to create an indentation in the center of each dough ball.
8. Fill with Preserves: Spoon a small amount of your chosen fruit preserves into each indentation. Avoid overfilling, as the jam may bubble over during baking.
9. Bake: Place the baking sheet in the preheated oven and bake for 10-12 minutes or until the edges are lightly golden.
10. Cool: Remove the cookies from the oven and let them cool on the baking sheet for 5-10 minutes before transferring to a wire rack to cool completely.

By following these steps, you can create mouthwatering Thumbprint Cookies that everyone will adore!
