Description
These buttery, melt-in-your-mouth thumbprint cookies feature a tender shortbread base and a vibrant jam center. A hint of cornstarch ensures a soft texture, making them the ultimate classic treat for any occasion.
Ingredients
- 1 cup unsalted butter, softened to room temperature
- 1/2 cup granulated sugar
- 1/4 cup light brown sugar, tightly packed
- 1 large egg yolk
- 1 teaspoon vanilla extract
- 2 1/4 cups all-purpose flour (280g)
- 2 tablespoons cornstarch
- 1/2 teaspoon salt
- Extra granulated sugar for rolling (optional)
- 1/2 cup jam or preserves (raspberry, strawberry, or apricot)
Instructions
- Cream the softened butter in a stand mixer fitted with the paddle attachment until smooth.
- Add the granulated sugar and light brown sugar, beating on medium-high for 30-60 seconds until fluffy.
- Mix in the egg yolk and vanilla extract until fully incorporated and the mixture is pale yellow.
- In a separate bowl, whisk together the all-purpose flour, cornstarch, and salt.
- Turn the mixer to low and gradually add the dry ingredients to the wet mixture, mixing until a cohesive dough forms.
- Roll the dough into 1-tablespoon sized balls, ensuring they are smooth and crack-free.
- Roll each ball in extra granulated sugar if desired, then place on a lined plate.
- Press a deep indent into the center of each ball using your thumb or the back of a measuring spoon.
- Freeze the indented dough for at least 30 minutes to prevent the cookies from spreading.
- Preheat oven to 375°F (190°C). Fill the frozen indents with slightly warmed jam.
- Bake for 11 minutes or until the edges just begin to turn golden. Cool completely on the baking sheet.
Notes
For the most professional look, use a round half-teaspoon measuring spoon to create uniform indents. If your dough feels dry or crumbly while rolling, the warmth from your hands will help soften the butter and bind the ingredients into a smooth ball. Ensure the jam is filled right to the brim before baking, as it will settle slightly in the oven.
