Preheat oven to 350 ˚F and line a cookie sheet with parchment paper.
Combine flour, cinnamon, baking powder, baking soda, and salt in a small bowl. Set aside. (1 cup flour, ¼ teaspoon cinnamon, ½ teaspoon baking powder, ½ teaspoon baking soda, ½ teaspoon salt)
Cream together the white sugar, brown sugar, butter, egg, and vanilla. (½ cup white sugar, ¾ cup brown sugar, ½ cup unsalted butter, 1 large egg, 1 teaspoon vanilla)
Combine wet and dry ingredients and mix until just combined.
Stir in the oatmeal and raisins until well mixed. (1 ½ cup old fashioned oats, ¾ cup raisins)
Place large scoops of dough onto the prepared baking sheet and bake for 10-15 minutes, or until lightly browned. Bake 10 minutes for softer cookies and longer for more crunchy.
While cookies are baking, make the glaze.
Combine all the powdered sugar, milk, and extract in a bowl. You can adjust the milk and powdered sugar to get your desired glaze consistency. (½ cup powdered sugar, 1 ½ tbs milk, ¼ teaspoon almond or vanilla extract)
When cookies are done, let them rest on the cookies sheet for a few minutes before transferring to a cooling rack. Drizzle with the glaze.
Enjoy!
Notes
These cookies are delicious and chewy straight from the oven. Store them in an air tight Ziploc bag and they will be good for several days. They will harden over time but they remain soft and chewy in the middle with a nice crunch on the outside. I actually really like them like this!
