What makes a snickerdoodle different from a sugar cookie rolled in cinnamon? Cream of tartar. This acidic ingredient gives the cookie its signature tang and creates a chewy, crackly texture that is absolutely unbeatable.

Ingredients You Need

• 1 cup (2 sticks) unsalted butter, softened
• 1 1/2 cups white sugar
• 2 large eggs
• 2 tsp vanilla extract
• 2 3/4 cups all-purpose flour
• 2 tsp cream of tartar (Do not skip this!)
• 1 tsp baking soda
• 1/2 tsp salt
• Coating: 1/4 cup sugar + 1 tbsp ground cinnamon mixed

Step-by-Step Instructions

1. Preheat oven to 375°F (190°C). Line a baking sheet with parchment paper.

2. In a large bowl, cream the softened butter and 1 1/2 cups of sugar together until light and fluffy (about 3 minutes). Beat in the eggs and vanilla.

3. Add the flour, cream of tartar, baking soda, and salt. Mix until a soft dough forms.

4. Mix the 1/4 cup sugar and cinnamon together in a small, shallow bowl.

5. Scoop out the dough (about 1.5 tablespoons each) and roll into smooth balls. Roll each ball generously in the cinnamon-sugar mixture.

6. Place on the baking sheet and bake for 9-11 minutes. They will puff up and then sink down, creating those beautiful crinkly tops. Don't overbake; they should look slightly soft in the center.
