The Secret to Perfect Snickerdoodles?

Soft, chewy, and coated in cinnamon sugar, this classic cookie gets its signature flavor and crackled top from one often-overlooked ingredient.

Some cookies are known for their chocolate chips. Others are famous for their frosting or fillings. But the snickerdoodle owes much of its distinctive character to an ingredient that many home bakers rarely use: cream of tartar.

At first glance, a snickerdoodle looks like an ordinary sugar cookie rolled in cinnamon. But bite into one, and the difference becomes clear.

A traditional snickerdoodle has a slightly tangy flavor, a soft and chewy center, and a delicate, crackled surface. Those qualities come partly from the combination of cream of tartar and baking soda.

Cream of tartar is a powdered acid commonly used in baking. When combined with baking soda, it produces carbon dioxide gas, helping the cookie rise and develop its characteristic texture.

It also adds a subtle tang that balances the dough’s sweetness and the cinnamon-sugar coating.

Without cream of tartar, the cookie may still taste delicious, but it loses some of the flavor that makes a traditional snickerdoodle special.

And the good news? These cookies are remarkably easy to make.

RECIPE AT A GLANCE

48

Cookies, approx.

375°F

Oven temperature

8–10 min

Baking time

Ingredients

For the cookie dough

• 2¾ cups all-purpose flour
• 2 teaspoons cream of tartar
• 1 teaspoon baking soda
• ½ teaspoon salt
• 1 cup (2 sticks) unsalted butter, softened
• 1½ cups granulated sugar
• 2 large eggs
• 1 teaspoon vanilla extract

For the cinnamon-sugar coating

• ¼ cup granulated sugar
• 2 tablespoons ground cinnamon

Directions

1. Preheat the oven. Heat to 375°F and line two baking sheets with parchment paper.
2. Combine the dry ingredients. In a medium bowl, whisk together the flour, cream of tartar, baking soda, and salt. Set aside.
3. Cream the butter and sugar. In a large mixing bowl, beat the softened butter and 1½ cups of sugar until light and fluffy, approximately three minutes. Add the eggs one at a time, mixing after each addition. Stir in the vanilla.
4. Make the dough. Gradually add the dry ingredients to the butter mixture, mixing on low speed just until combined. Avoid overmixing.
5. Prepare the coating. In a shallow bowl, combine the remaining ¼ cup of sugar with the cinnamon.
6. Shape the cookies. Roll the dough into balls approximately 1¼ inches in diameter. Roll each ball in the cinnamon-sugar mixture until thoroughly coated.
7. Bake. Arrange the dough balls about two inches apart on the prepared baking sheets. Bake for 8–10 minutes, until the edges are set, but the centers still appear slightly soft and puffed.
8. Cool. Leave the cookies on the baking sheet for five minutes before transferring them to a cooling rack. As they cool, the centers will settle, and the tops will develop their familiar crackled appearance.

A Few Tips for Better Snickerdoodles

The secret to a soft snickerdoodle is not overbaking it.

When the cookies first come out of the oven, the centers may look slightly underdone. That’s exactly what you want. They will continue to firm up as they cool.

If the dough becomes too soft or sticky to roll easily, refrigerate it for about 20 minutes before shaping the cookies.

For the classic flavor, use cream of tartar and baking soda instead of baking powder. Although baking powder can provide leavening, it won’t reproduce the same distinctive tang.

Finally, don’t skip the cinnamon-sugar coating. That sweet, warmly spiced exterior is essential to the snickerdoodle experience.

A Cookie That Never Goes Out of Style

Snickerdoodles don’t require elaborate decorations, expensive ingredients, or complicated techniques.

They’re the kind of cookie that feels right at home on a holiday dessert tray, at a neighborhood gathering, or beside a glass of milk on an ordinary afternoon.

With their soft centers, cinnamon-sugar coating, and unmistakable tang, they’re proof that sometimes the simplest recipes become family favorites.

And if you’ve ever wondered what makes a snickerdoodle different from a cinnamon-sugar cookie, now you know.

The secret is in the cream of tartar.
