Preheat oven to 350° F. Cream butter and sugar until blended. Add eggs, extract and, if using, bourbon. Mix until well incorporated.
Blend dry ingredients in a separate bowl then add 1 cup at a time, mixing between each cup. Dough should cleanly pull away from the sides of the mixing bowl. If not, add ¼ cup of flour.
Take a generous portion of dough out of mixing bowl to roll out between parchment paper. Fluff the brown sugar-cinnamon mixture with a fork to evenly incorporate.
With the dough rolled out, generously sprinkle the brown sugar-cinnamon mixture over it by hand. Roll dough upon itself like a cinnamon roll. Then re-roll the dough, sprinkle again and cut out your preferred shapes. Repeat this process until all dough is used.
Bake cookies on parchment paper-lined baking sheet for 9 to 12 minutes as ovens may vary. Baking time is based upon dough flattened to a 3/8-inch thickness. If rolled thinner, reduce baking time.
