Preheat and Prepare
Preheat your oven to 375°F (190°C). Line a prepared baking sheet with parchment paper or a silicone baking mat.
This ensures your cookies bake evenly and don’t stick.
Cream the Butter and Sugar
In a large bowl (or the bowl of a stand mixer), beat together the unsalted butter and granulated sugar until light and fluffy — about 2–3 minutes on medium-high speed.
This step adds air to the dough, helping your cookies bake up soft and chewy.
Add the Wet Ingredients
Beat in the eggs one at a time, followed by the vanilla extract.
Scrape down the sides of the bowl to make sure everything mixes evenly.
The dough will look creamy and smooth — and it already smells amazing.
Combine the Dry Ingredients
In a separate bowl, whisk together the flour, cream of tartar, baking soda, and salt.
Gradually add the dry ingredients to the wet ingredients, mixing just until combined. The dough should be soft but not sticky.
Roll in Cinnamon Sugar
In a small bowl, mix the ¼ cup granulated sugar and 1 ½ teaspoons cinnamon.
Using a cookie scoop or tablespoon, roll the dough into 1 ½-inch dough balls, then toss each one in the cinnamon sugar mixture until evenly coated.
Bake the Snickerdoodles
Place the coated dough balls about 2 inches apart on the prepared baking sheet.
Bake for 8–10 minutes, until the edges are set and lightly golden, but the centers still look soft.
Cool and Enjoy
Remove from the oven and let the cookies rest on the baking sheet for 2 minutes, then transfer them to a wire rack to cool completely.
Try not to eat them all while they’re still warm — though I always “test” one straight from the pan for good measure!
