Soft, chewy snickerdoodle cookies with crisp edges, a tender middle, and that signature cinnamon sugar tang. One bowl, no chilling, ready in under 20 minutes.
Preheat the oven to 350 and line the baking sheet with a silicone sheet, parchment paper, or coat with baking spray.
Using a mixer and a large bowl, blend butter until creamy.
Add the white and brown sugar to your bowl and mix well.
Mix in the vanilla extract and egg until well combined.
Add the flour, baking soda, salt and cream of tartar to your bowl. Mix thoroughly and set aside.
In a small bowl, prepare the cinnamon mixture that you will use to coat your cookie dough by combining the 1⁄4 c sugar with 2 tsp of cinnamon and mix well.
Next, using a tablespoon, scoop the cookie dough and form a ball using your hands.
Roll the ball in the cinnamon sugar mixture and place onto your baking sheet. Repeat to desired amount.
Bake in the oven for 12 minutes.
Allow the cookies to cool for 5 minutes on the baking sheet and transfer to a cooling rack to cool completely.
Notes
Don't overbake. You want soft and chewy, so pull them when the bottoms are lightly browned. If the tops look a touch underdone, good. They keep cooking on the hot pan.
Measure your flour with the spoon and level method. Pack the cup and you'll end up with dry, crumbly cookies.
Roll in the cinnamon sugar right after forming the balls. The warmth from your hands helps the sugar stick. Wait too long and it slides right off.
Use a scoop so every ball is the same size and they bake evenly.
