A snickerdoodle is a type of cookie made with butter or oil, sugar, and flour rolled in cinnamon sugar. Eggs may also sometimes be used as an ingredient, with cream of tartar and baking soda added to leaven the dough. Snickerdoodles are characterized by a cracked surface and can be crisp or soft depending on preference.
Snickerdoodles are often referred to as "sugar cookies". However, traditional sugar cookies are often rolled in white sugar whereas snickerdoodles are rolled in a mixture of white sugar and cinnamon.
1/2 cup salted butter, softened
1/2 cup vegetable shortening
1 1/2 cups plus 2 tablespoons sugar
2 medium eggs
2 3/4 cups all-purpose flour
2 teaspoons cream of tartar
1 teaspoon baking soda
1/4 teaspoon fine salt
2 teaspoons ground cinnamon
Preheat the oven to 400 degrees F.
In a large bowl, combine the butter, shortening, 1 1/2 cups sugar and the eggs and mix thoroughly with an electric mixer on medium speed until creamy and well combined, 1 to 2 minutes. Sift together the flour, cream of tartar, baking soda and salt, and stir into the shortening mixture.
In a small bowl, stir together the remaining 2 tablespoons sugar with the cinnamon.
Shape the dough into 1 1/2-inch balls (1 tablespoon per ball), and roll each ball in the cinnamon-sugar. Arrange the dough balls 2 inches apart on ungreased cookie sheets. Bake two sheets at a time until the edges of the cookies are set but the centers are still soft, 8 to 10 minutes, rotating the sheets halfway through. Transfer the cookies to wire racks for cooling. Repeat with the remaining dough balls. Store in an airtight container.
