Preheat oven to 350. In a large bowl cream together butter, brown sugar, and granulated sugar until light and fluffy, this will take 2-3 minutes.
Next, add eggs, maple extract and maple syrup and mix until combined. In another bowl, whisk together the flour, baking soda, cinnamon, ginger, and salt.
Add the dry mixture to the wet ingredients, mixing until just combined. Add in oats and mix them all together. Drop dough onto cookie sheets.
Dough will spread out so keep cookies 2-3 inches apart. Bake for 13-15 minutes or until golden brown. Makes about 3 dozen depending on size you make them. Once cooled add maple frosting below.
Frosting Instructions
Bring sugar, milk and butter to a boil in a saucepan on top of the stove. Boil for 1 minute stirring constantly. Remove and add maple extract and powdered sugar. Stir. Frost or drizzle over cookies.
Notes
You can add more milk if frosting gets too thick. Just keep adding until consistency you like.
