Use the bottom of a 1/2-cup measuring cup to flatten the cookies to the perfect size. Be sure to use salted butter.
3 2/3 cups all-purpose flour
2 1/2 teaspoons cream of tartar
1 1/2 teaspoons baking soda
1/2 teaspoon kosher salt
1/3 cup unsweetened cocoa
1 3/4 cups butter, softened
2 1/2 teaspoons vanilla extract
2 1/3 cups sugar, divided
4 teaspoons cinnamon, divided
3 large eggs
How to Make It
Stir together 2 cups flour, 1 1/4 tsp. cream of tartar, 3/4 tsp. baking soda, and 1/4 tsp. salt in a medium bowl. Stir together cocoa and remaining 1 2/3 cups flour, 1 1/4 tsp. cream of tartar, 3/4 tsp. baking soda, and 1/4 tsp. salt in another medium bowl.
Beat butter, vanilla, 2 cups sugar, and 1 tsp. cinnamon at medium speed with an electric mixer until creamy. Add eggs, 1 at a time, beating well after each addition. Spoon half of butter mixture into cocoa mixture; spoon remaining butter mixture into flour mixture.
Beat plain batter until just blended; beat chocolate batter until just blended. Chill both mixtures 30 minutes.
Preheat oven to 350°. Stir together remaining 1/3 cup sugar and 3 tsp. cinnamon in a small bowl. Drop plain dough by level tablespoonfuls onto aluminum foil. Top each with 1 Tbsp. chocolate dough; roll together into a ball. Roll in cinnamon-sugar; place 3 inches apart on parchment paper-lined baking sheets, and flatten.
Bake at 350° for 14 minutes or until edges are lightly browned, lightly tapping baking sheets halfway through to deflate cookies. Cool 5 minutes; transfer to wire racks, and cool.
Marble-Cinnamon Sandwich Cookies: Spread 2 cups cinnamon-raisin swirl peanut butter (such as Peanut Butter & Co.) onto half of cookies (about 2 Tbsp. per cookie); top with remaining cookies.
The flavor of these is excellent. I ended up making them much smaller than the recipe called for as mine spread excessively in the oven -- even after the dough had been chilled in the refrigerator overnight and without flattening the balls after rolling in the sugar. My husband and my son both loved them (and I really like that there is no shortening in the recipe) however I really hate putting square cookies on a holiday cookie plate after I've had to cut them apart on the cookie sheet. I will be making these again. My son's comment: " I love Snickerdoodles however I have always felt that a cookie without chocolate is just missing something. This cookie solves that problem".
The best snickerdoodles I've ever eaten! These are large cookies. I cooked mine for exactly 14 minutes and they are perfect: moist but firm. You can taste the chocolate much better when they've cooled. Next time I might decrease the cinnamon in which you roll them just a tad.
