Instructions
Preheat oven to 350 degrees F. Have ready 2 ungreased or parchment lined cookie sheets.
Stir flour, baking soda, baking powder, salt and cinnamon together in a medium bowl; set aside. Be sure the dry ingredients are very evenly blended.
Beat the butter and both sugars together just until creamy. Add egg and vanilla and beat just until eggs are blended in. Add the flour mixture to the butter mixture and stir just until mixed. Stir in oats, raisins and pecans (if using)
Using a tablespoon measure or a small cookie scoop OR a medium cookie scoop,, scoop up dough and arrange scooped dough balls on a plate. Cover and chill for a few hours. Alternatively, scoop and bake immediately.
Bake 10-12 minutes for small cookies or about 12 minutes for the slightly larger ones, one sheet at a time, on center rack. Remove from oven; let cookies sit on baking sheet for 2-4 minutes. Carefully transfer to a rack to cool.
