In a blender or food processor blend the Gluten-Free Oats (1 1/4 cup) until fine powder forms. Remove from the blender and pass through a fine-mesh sieve to get any chunks out. (This isn't necessary for making the dough, but it will make your final product smoother.)
In a medium-size bowl, cream the Unsalted Butter (7 tablespoon), Granulated Sugar (2/3 cup), Brown Sugar (2 tablespoon), and Ground Cinnamon (1/4 teaspoon) with a spatula or hand mixer until well-combined.
Add the Salt (1/4 teaspoon), Pure Vanilla Extract (1 tablespoon), Milk (3 teaspoon), and mix again to combine.
Add the oat flour. Mix until completely combined, then fold in the Butterscotch Chips (1/4 cup).
Using an ice cream scoop, scoop dough to serve. Garnish with Sprinkles (to taste) or candies of your choice.
