Polish Cinnamon Cookies Recipe - Ciasteczka Cynamonowe

In a large bowl, cream together butter and sugar. Mix in zest and 2 eggs. In a separate medium bowl, whisk together flour, baking powder, and cinnamon. Add to butter mixture mixing until a stiff dough results. Wrap dough in plastic wrap and refrigerate 12 hours or overnight.

Heat oven to 350 degrees. On parchment-lined baking sheets roll out dough 1/4-inch thick and cut with cookie cutters into desired shapes, leaving 1 inch between cookies. Stars and crescent moons are nice. Remove scraps and brush shapes with egg-yolk glaze and bake about 15 minutes or until lightly golden around the edges but not brown. If desired, sprinkle glazed cookies with cinnamon sugar before baking. Cool completely on a wire rack. Repeat with remaining dough. Store in an airtight container.
