In a large mixing bowl, beat softened butter with granulated sugar using an electric mixer on medium speed until pale and fluffy, about 2–3 minutes.
02 -
Add the egg yolk and pure vanilla extract. Mix on medium speed until fully incorporated.
03 -
Add flour and salt gradually, mixing on low speed just until a soft dough forms. Do not overmix to maintain a tender texture.
04 -
Wrap the dough tightly in plastic wrap and refrigerate for at least 30 to 45 minutes to ensure structure during baking.
05 -
Preheat oven to 175°C and line a baking sheet with parchment paper or a silicone baking mat.
06 -
Scoop tablespoon-sized portions of chilled dough, roll into balls, and arrange 5 cm apart on the prepared baking sheet. Use your thumb or the back of a ½ teaspoon to gently press an indentation into each dough ball.
07 -
Spoon approximately 2.5 ml of jam into each indentation, taking care not to overfill.
08 -
Bake for 12–14 minutes until edges are just set and barely golden. Avoid overbaking to retain a soft texture.
09 -
Allow to cool on the baking sheet for 5 minutes, then transfer cookies to a wire rack to cool fully.
10 -
If desired, whisk together powdered sugar, milk, and almond or vanilla extract. Drizzle glaze over completely cooled cookies for a festive finish.
