Soft, chewy snickerdoodle cookies with crisp edges, warm cinnamon-sugar coating, and classic cream-of-tartar tang.
1/2 cup (114 g) salted butter, softened
3/4 cup + 2 tbsp (175 g) granulated sugar, divided
1 large egg, room temperature
1 tsp vanilla extract
1/4 tsp kosher salt
1 tsp cinnamon, divided
1/4 tsp nutmeg
1/2 tsp baking powder
3/4 tsp cream of tartar
1 3/4 cups (218 g) all-purpose flour
1. Cream butter and 3/4 cup sugar; add egg and vanilla.
2. Mix in salt, 1/2 tsp cinnamon, nutmeg, baking powder, cream of tartar.
3. Add flour; mix just to form soft dough.
4. Roll dough balls in remaining sugar + cinnamon.
5. Bake until edges set and tops crackle; cool on rack.
Chill briefly if dough is too soft.
Roll generously in cinnamon sugar for crackle.
Store airtight for soft centers; freeze dough balls for later baking.
