Preheat oven to 400°F (200°C).

Grease a baking sheet.

Combine flour and baking powder in a bowl.

Create a well in the center and add egg, sugar, and spices.

Gradually incorporate the wet ingredients into the dry ingredients to form a thick dough.

Cut cold butter into pieces and add to the dough along with ground almonds.

Cover with flour and knead into a smooth dough. Refrigerate if sticky.

Optionally, rest dough in the refrigerator for an hour.

Roll dough thinly (1/8 inch). Sprinkle with flaked almonds (optional) and press lightly.

Cut out cookies using Christmas cookie cutters.

Place cookies on the greased baking sheet.

Bake for about 15 minutes until golden brown.

Cool on the baking sheet before serving.
