Sour Cream Sugar Cookies

These sugar cookies stay soft for days thanks to a full ½ cup of sour cream worked into the dough. They bake up puffy and tender with a slight tanginess hiding under the sparkly sugar crust. No chilling required, no rolling pin needed.

The sour cream does two things for this dough. It adds fat and acid, which means a more tender, moist cookie with a finer crumb than an all-butter version. The acid also reacts with the baking soda, giving extra lift that makes these cookies puff into soft, pillow-like rounds.

Each ball of dough gets rolled in sugar before flattening with the bottom of a glass. This double step creates a sweet, slightly crunchy exterior that contrasts the soft, cakey interior. The sugar coating is what gives these their signature sparkle.

Seven to eight minutes at 400°F (200°C) is fast. Pull them when they’re just barely set. They should look slightly underdone when you take them out. They firm up during the cool-down on the sheet.

Chef Tips

• Use softened butter for easier mixing. Cold butter makes the dough too stiff to work with.
• Roll dough balls gently in sugar. Don’t compress them. The flattening comes next with the glass.
• Flatten to ¼ inch thickness for even baking. Thicker cookies stay raw in the center.
• These are a blank canvas for decorating. Add sprinkles to the sugar or frost after cooling.

Variations

• Lemon sugar cookies: Add 1 tablespoon lemon zest to the dough for a citrusy twist.
• Brown sugar version: Replace white sugar with brown sugar in the dough for a chewier, more caramel-flavored cookie.
• Frosted: Top cooled cookies with a simple vanilla buttercream for a bakery-style finish.
