GRINCH COOKIES

Steps:

• Whisk flour, baking soda, cream of tartar, and salt together in a medium bowl.
• Cream butter and 1 cup sugar in a large bowl. Beat in egg, vanilla, and food coloring. Gradually stir in the flour mixture.
• Scoop dough with a medium cookie scoop into 1/8-cup balls. Place in a plastic container and refrigerate for 1 hour.
• Preheat the oven to 375 degrees F (190 degrees C). Line a baking pan with parchment paper. Stir 2 tablespoons sugar and cinnamon together in a small bowl.
• Remove dough from the refrigerator. Roll each ball in the cinnamon sugar and arrange on the prepared pan, about 2 inches apart. Press a candy heart into the center of each cookie.
• Bake in the center of the preheated oven until edges are golden brown, 10 to 11 minutes. Cool on the baking sheet for 1 minute before removing to a wire rack to cool completely.
