Cookie Butter Snickerdoodles

I made these for Christmas this year, and they might be my new favorite way to make snickerdoodles! The cookie butter adds a little extra spice and covers up the tang of the cream of tartar quite nicely. The cookies also stayed soft for a good, long time. (Adapted from here.)

Cookie Butter Snickerdoodles

3 c flour
1 tsp baking soda
1/2 tsp cream of tartar
1/2 tsp cinnamon
1/2 tsp salt
3/4 c unsalted butter, softened
3/4 c light brown sugar
1/2 c sugar
1/2 c cookie butter
2 large eggs
1 tsp vanilla extract
cinnamon-sugar mixture:

     1 c sugar

     1 Tbsp cinnamon

Preheat oven to 350°F. Line baking sheets with silpat liners.
Whisk together the flour, baking soda, cream of tartar, cinnamon, and salt. Set aside.
Using a hand mixer on medium speed, beat the butter, brown sugar, sugar, and cookie butter until thoroughly combined. Add the eggs, one at a time, mixing well after each addition. Mix in the vanilla.
Reduce mixer speed to low. Gradually add the flour mixture, mixing just until combined.
Using a small cookie scoop, roll the dough into balls, 1 at a time. Then roll each ball in the cinnamon-sugar mixture to coat. Place 2 inches apart on the prepared pans.
Bake, one pan at a time, 8 to 10 minutes or until lightly browned. Cool on the pans for 5 minutes. Then transfer the cookies to wire racks to cool completely.

Yield: 4-5 dozen cookies
