Thick snickerdoodle cupcakes topped with creamy frosting and a sprinkle of cinnamon sugar.

# What You'll Need:

→ Cookie Base

01 - ½ cup unsalted butter, softened
02 - ¾ cup granulated sugar
03 - ½ cup light brown sugar, packed
04 - 1 large egg
05 - 1 teaspoon vanilla extract
06 - 1 ¼ cups all-purpose flour
07 - 1 tablespoon cornstarch
08 - ¼ teaspoon cream of tartar
09 - ½ teaspoon baking powder
10 - ½ teaspoon baking soda
11 - ¼ teaspoon fine salt
12 - 2 teaspoons ground cinnamon (for coating)
13 - 2 tablespoons granulated sugar (for coating)

→ Cream Cheese Frosting

14 - 4 ounces full-fat cream cheese, softened
15 - 2 tablespoons unsalted butter, softened
16 - ½ teaspoon vanilla extract
17 - 1 cup powdered sugar, sifted

# Steps to Follow:

01 - Cream together softened butter, granulated sugar, and brown sugar until light and fluffy using an electric mixer.
02 - Add egg and vanilla extract to the creamed mixture, beating until smooth and creamy.
03 - In a separate bowl, whisk together flour, cornstarch, cream of tartar, baking powder, baking soda, and salt; gradually add into the wet mixture until just combined and no dry flour remains.
04 - Scoop cookie dough into 2 tablespoon-sized balls using a cookie scoop, then roll each ball in the cinnamon-sugar mixture until fully coated.
05 - Place dough balls on a non-stick baking sheet or parchment paper, gently flatten each to approximately 1 inch thick, and bake in a preheated oven at 350°F (175°C) for 12-14 minutes until edges are set but centers remain soft.
06 - While cookies cool, beat together cream cheese, butter, vanilla extract, and powdered sugar until smooth and creamy; refrigerate briefly if necessary to firm up.
07 - Spread or pipe the cream cheese frosting generously onto each cooled cookie, then lightly dust the tops with remaining cinnamon-sugar mixture before serving.

# Extra Suggestions:

01 - For best results, chill the dough briefly before baking to improve texture.
02 - Store frosted cookies refrigerated in an airtight container for up to 7 days.
03 - To freeze, keep cookies and frosting separately and thaw overnight in the refrigerator before assembling.
