1/2 cup granulated sugar
1/2 cup brown sugar, packed
1 egg and 1 egg yolk
1/4 cup real maple syrup
2 teaspoons vanilla extract

1 teaspoon baking soda
1 teaspoon cream of tartar
1/2 teaspoon salt
1 teaspoon ground cinnamon
CINNAMON SUGAR FOR ROLLING
1/4 cup granulated sugar

INSTRUCTIONS
Preheat oven to 350 degrees.
In the bowl of an electric mixer fitted with the paddle attachment, cream butter, sugar and brown sugar together on medium-high speed until pale and fluffy.
Add egg and egg yolk and cream together again.
Add maple syrup and vanilla extract and mix until incorporated.
In a medium bowl, whisk flour, baking soda, cream of tartar, salt and cinnamon together. Slowly add the flour ingredients to the electric mixing bowl on low speed. Mix until a dough forms, being careful not to overmix. Use a rubber spatula to scrape down the sides of the mixing bowl, and mix one more time.
Add additional sugar and cinnamon to a small bowl and mix together. Use a large scoop to make 2 inch balls of dough and roll them in the cinnamon-sugar mixture.
Place the dough balls on a baking sheet (6 per sheet) and bake at 350 degrees for 13-15 minutes. The cookies will be puffed and cracked on top, but will look slightly unset in the center.
