Preparation Steps

• In a medium bowl, whisk together the flour, cream of tartar, baking soda, salt, and chai spice.
• In a separate large bowl, use an electric mixer to cream butter and sugars until fluffy, about 3 minutes. Add eggs and vanilla and beat an additional 1-2 minutes.
• Pour the dry ingredients into the butter mixture and mix on low speed just until the flour is incorporated. Do not overmix.
• Refrigerate the dough for at least 30 minutes, or overnight.
• When ready to bake, preheat the oven to 350°F.
• For the topping, mix the granulated sugar and chai spice in a small bowl.
• Scoop the dough into 1.5 tablespoon scoops and roll each into a ball. Roll the ball in the chai-sugar mixture.
• Arrange about 3-inches apart on a cookie sheet. Bake for 7-10 minutes, or until the edges of the cookies are just starting to turn brown.
• Allow to cool on the cookie sheet for several minutes, then transfer to a wire cooling rack.
