Combine all-purpose flour and ground cardamom in a medium sized bowl.

In a large bowl, cream butter and sugar until light and fluffy, about 2 minutes. Add egg and beat until combined.

Beat in as much of the flour mixture as possible. Add the rest and knead until dough comes together.

Divide dough in half. Wrap each portion in plastic and chill for 30 minutes.

Roll out dough on a pastry mat or lightly floured surface to 3/16th inch thick.

Cut into desired shape using 2½ inch cookie cutters. Transfer to a cookie sheet. Repeat until all dough is used up.

Bake cookies in a 350°F (180°C) oven for 12 to 14 minutes or until bottoms are very lightly browned.

Transfer to a wire rack to cool completely.

When cookies are completely cooled, decorate as desired.
