Cream the softened butter and sugar together until light and fluffy.

Add the egg and strawberry flavoring, mixing until fully incorporated.

In a separate bowl, whisk together the flour and baking powder.

Gradually add the dry mixture to the wet ingredients until a soft dough forms.

Chill the dough for 30–45 minutes to prevent spreading.

Preheat the oven to 350°F (175°C).

Roll the chilled dough into small balls and coat them in granulated sugar.

Place the coated dough balls on a baking sheet.

Bake until the cookies are set but still soft, about 10-12 minutes.

Press a chocolate kiss gently into the center of each cookie immediately after removing them from the oven.

Allow the cookies to cool on the baking sheet for a few minutes before transferring to a wire rack.
