Method
Step 1: Mix the Wet Ingredients
- Beat the softened butter, granulated sugar, and brown sugar until smooth. Add the eggs and vanilla. Mix until the batter looks creamy.
Step 2: Add the Dry Ingredients
- Whisk the flour, cream of tartar, baking soda, and salt. Add the dry mix to the wet batter. Stir until a soft dough forms.
Step 3: Chill (Optional but Helps)
- Chill for 30 minutes to keep the cookies thick and soft during baking.
Step 4: Shape and Roll
- Mix the cinnamon and sugar for rolling. Scoop dough into balls, then roll each one in the cinnamon sugar.
Step 5: Bake
- Place on lined baking sheets. Bake at 350°F (175°C) for 10–11 minutes. Remove once the edges look set. The centers may look soft—this keeps them chewy.
Step 6: Cool
- Let them cool on the pan for 5 minutes, then transfer to a rack
