Chill the Dough: This is crucial! Chilling the dough for at least 30 minutes (or even overnight) prevents the cookies from spreading too much and intensifies the flavors.
Don’t Overbake: Snickerdoodles should be slightly soft in the center when you take them out of the oven. They will continue to bake as they cool.
Use a Cookie Scoop: A cookie scoop ensures that all your cookies are the same size, so they bake evenly.
Fresh Cinnamon Sugar: Mix your cinnamon and sugar right before rolling the dough balls for the best flavor.
Room Temperature Butter: Make sure your butter is softened, but not melted. It should be soft enough to easily cream with the sugar.
Rolling Technique: Roll the dough balls gently in the cinnamon-sugar mixture to avoid flattening them.
Even Baking: Rotate the baking sheet halfway through baking to ensure even browning.
