Soft, chewy, buttery cookies coated in cinnamon and sugar. This snickerdoodle cookie recipe turns out perfect every time with a classic flavor and melt-in-your-mouth texture.
Preheat your oven to 350°F (177°C) and line baking sheets with parchment paper.
In a medium bowl whisk together flour, cream of tartar, baking soda, cinnamon, and salt.
In a large bowl cream your softened butter, granulated sugar, and brown sugar together until light and fluffy.
Add in your egg and egg yolk plus vanilla. Mix until fully combined.
Slowly add dry mix into your wet mix, stirring just enough to combine.
In a small bowl mix sugar and cinnamon for coating.
Roll dough into balls about 1.5 tablespoons each, then roll in cinnamon-sugar coating and place on baking sheets spaced 2 inches apart.
Bake 9-11 minutes or until edges are set and centers are slightly underbaked.
Let cookies rest 5 minutes on the baking sheet before moving to a wire rack to cool completely.
Notes
Store in an airtight container at room temp for up to 4 days or freeze up to 3 months. For best results, reheat frozen cookies in a low oven for a few minutes.
