Prep: Preheat oven to 350°F. Line a few baking sheets with parchment paper.
Mix the dry ingredients: In a medium bowl, whisk together the flour, cream of tartar, baking soda, salt, cinnamon, and cardamom. Set aside.
3 cups all purpose flour, 2 tsp. cream of tartar, 1 tsp. baking soda, 1/2 tsp. fine salt, 1/4 tsp. ground cinnamon, pinch of ground cardamom
Cream the butter and sugars: In a stand mixer fitted with the paddle attachment (or using a hand mixer), cream the softened butter, granulated sugar, and brown sugar on medium speed for 2-3 minutes, until light and fluffy. Scrape down the sides of the mixing bowl as needed.
1 cup butter, 1 cup granulated sugar, 1/2 cup light brown sugar
Add eggs: Add the eggs one at a time, mixing well after each addition.
2 large eggs
Mix in vanilla: Mix in the vanilla bean paste.
1 Tbsp. vanilla bean paste
Combine wet and dry: Add the dry ingredients to the bowl and mix on low until just combined. Do not overmix.
Scoop and roll: Using a 1½ tablespoon cookie scoop, scoop and roll each ball in the holiday-colored sanding sugars to fully coat. I like to set up a little station with 3 bowls and place each sugar in a bowl and alternate colors as I go. Also, feel free to add a small pinch of cinnamon into the sanding sugars to get that snickerdoodle cinnamon sugar vibe. Christmas red/green/white sugar for rolling
Bake: Place cookies on the prepared baking sheets, spacing them 2 inches apart. Bake for 7-9 minutes, or until edges look set but centers appear soft and slightly underdone. I always pull mine out at 7 minutes. Do not overbake because they will continue to set as they cool, and there’s nothing worse than a dry snickerdoodle! Start Timer
Finish: If needed, cookie-scoot into perfect circles using a round cutter right after baking. Sprinkle a little extra Christmas sugar on top for sparkle. Cool on the baking sheet for 5 minutes, then transfer to a wire rack. ENJOYY!! Aren’t they so cute?!
