Ingredients
Cookie Dough
- 1 cup (226 g) unsalted butter, softened to room temperature
- ⅓ cup (70 g) sugar
- ⅓ cup (70 g) light brown sugar, tightly packed
- 1 large egg yolk
- ¾ teaspoon vanilla flavoring
- 2 ¼ cups (280 g) all purpose flour
- 2 teaspoons cornstarch
- ½ teaspoon salt
Finishing
- ½ cup sugar for rolling (optional)
- ⅓ cup (105 g) jam or preserves of your choice (e.g., raspberry preserves)
Instructions
- Cream the Butter: Place the softened unsalted butter in the bowl of a stand mixer (or use a large bowl with an electric hand mixer) and beat until creamy and smooth.
- Add Sugars: Scrape down the sides of the bowl, add sugar and light brown sugar, then beat on medium-high speed for about 30 to 60 seconds until well combined and fluffy.
- Mix in Egg Yolk and Vanilla: Add the egg yolk and vanilla flavoring to the bowl and beat well to incorporate evenly.
- Prepare Dry Ingredients: In a separate bowl, whisk together all purpose flour, cornstarch, and salt to ensure they are well blended.
- Combine Dry and Wet Ingredients: With the mixer on low speed, gradually add the flour mixture to the wet ingredients until completely combined. The dough will be dry and crumbly; pause occasionally to scrape the sides and bottom of the bowl. If necessary, finish kneading the dough by hand until it fully comes together.
- Form Dough Balls: Scoop the dough into 1 tablespoon-sized balls and roll them well by hand, ensuring each ball is smooth with no cracks or seams to prevent cracking during baking.
- Chill the Dough: Place the dough balls in the refrigerator for about 30 minutes to firm up before baking. (Note: chilling time based on recipe total time)
- Create Thumbprints and Fill: Remove chilled dough balls from the refrigerator. Use your thumb or the back of a small spoon to gently press an indentation into the center of each ball. Be careful not to press too deeply to avoid breaking the cookie.
- Fill with Jam: Spoon approximately ½ teaspoon of your chosen jam or preserves into each indentation, filling but not overflowing.
- Bake the Cookies: Preheat your oven to 350°F (175°C). Arrange the prepared cookies on a baking sheet lined with parchment paper or a silicone baking mat, spacing them evenly. Bake for 11 minutes until the edges are lightly golden but the centers are still soft.
- Cool and Serve: Remove cookies from the oven and allow them to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely. Optionally, roll the dough balls in sugar before making the thumbprints for added sweetness and slight texture on the exterior.
Notes
- You can use any flavor of jam or preserves you like, raspberry is classic.
- Rolling the dough balls well and ensuring no cracks will prevent the cookies from splitting during baking.
- Chilling the dough before making the thumbprints helps keep the cookies from spreading too much in the oven.
- Rolling the dough balls in sugar before pressing thumbprints adds a sweet crunchy coating.
- Store cookies in an airtight container at room temperature for up to a week or freeze for longer storage.
