Snickerdoodles with Crispy-Chewy Edges
Learn why cream of tartar transforms these cinnamon-sugar cookies into tender, tangy treats with just the right amount of spread
Cream of tartar is an acid that does two essential things in snickerdoodles. First, it reacts with baking soda to create lift and structure, giving you a cookie that’s sturdy enough to hold that signature crackle. Second, and this is the real magic, it prevents sugar crystallization during mixing, which keeps your dough tender and prevents the cookies from becoming grainy or tough. You’ll notice the dough stays smooth and workable, never getting that gritty texture that sometimes happens with baked goods. The acid also contributes a subtle tang that balances the sweetness of the cinnamon sugar coating, making these cookies more interesting than they first appear.
When you cream your butter and sugar together, the cream of tartar is already there, quietly doing its job. The dough should look pale and fluffy, almost like cumulus clouds. You’re not just mixing ingredients—you’re aerating the butter and creating tiny air pockets that will expand in the oven. The cinnamon sugar coating serves double duty as both flavor and texture, creating that signature crinkled surface that catches light and makes these cookies unmistakably snickerdoodles.

-
Cream the softened butter and 3/4 cup sugar together for about 3 minutes, until the mixture is pale, fluffy, and noticeably lighter in color than when you started—you should be able to see air pockets throughout
-
Add the egg and vanilla, then beat until the mixture is homogeneous and slightly increased in volume, about 1 minute
-
In a separate bowl, whisk together the flour, baking soda, cream of tartar, and salt until no streaks of white remain
-
Fold the dry ingredients into the wet ingredients using a rubber spatula until just combined—the dough should feel soft and slightly sticky, never dry or crumbly
-
Mix the 2 tablespoons sugar and cinnamon together in a small bowl until evenly distributed
-
Scoop dough into 1-inch balls and roll each one in the cinnamon-sugar mixture until completely coated with a generous, visible layer
-
Space the cookies at least 2 inches apart on a parchment-lined baking sheet—they will spread noticeably
-
Bake at 375°F for 11 to 13 minutes, until the edges are set and lightly golden but the centers still look slightly underbaked and soft, like they might jiggle if you moved the pan
-
Let the cookies cool on the baking sheet for 5 minutes—they’ll firm up slightly and develop their characteristic crackled surface—then transfer to a cooling rack
