Cream the softened butter and sugar until light and fluffy, then mix in the egg, vanilla, and almond extract to create a smooth base that ensures even flavor throughout.
Whisk together the dry ingredients separately, then gradually incorporate them into the wet mixture to form a soft dough without overworking it.
Shape the dough into small balls, flatten them slightly, and top with sliced almonds to create an even baking surface and attractive finish.
Chill the shaped cookies briefly to help them maintain structure and improve their final texture during baking.
Bake in a preheated oven until the edges turn golden, then allow them to cool gradually so they develop a crisp and stable structure.
