Soft frosted-style sugar cookies on a plate

Soft sugar cookies — the pillowy, cakey kind that stay tender for days — are all about restraint: modest oven time, cream of tartar for tang and tenderness, and a sour cream–enriched dough that bakes up thick instead of spreading thin. These are the cookies of school parties and cookie exchanges, happy plain, rolled in sprinkles, or frosted pink like the grocery-store legends. The dough chills an hour (non-negotiable; it's soft by design), and then they bake in eleven gentle minutes to just-set perfection.

Ingredients

12 tbsp (1 1/2 sticks) butter, softened
1 1/4 cups sugar, plus 1/3 cup for rolling
1 egg + 1 yolk
1/3 cup sour cream
2 tsp vanilla extract
2 3/4 cups flour
1 tsp baking soda
1/2 tsp cream of tartar
1/2 tsp salt

Instructions

Beat the butter and sugar until pale and fluffy, 2–3 minutes.
Beat in the egg, yolk, sour cream, and vanilla.
Fold in the flour, baking soda, cream of tartar, and salt just until combined. The dough will be soft — that's correct.
Chill 1 hour (up to 2 days).
Heat the oven to 350°F. Roll 2-tablespoon balls, roll them in sugar, and space 2 inches apart on parchment-lined pans. Flatten each slightly with the bottom of a glass.
Bake 10–12 minutes until the tops look set and matte but the cookies show zero browning beyond the very bottom edge.
Rest on the pan 5 minutes, then rack. Frost when fully cool, if frosting.

Ingredient Substitutions

Ingredient	Substitute	Notes
Sour cream	Plain Greek yogurt	Same tender crumb
Cream of tartar	Skip it, use 1 tsp baking powder + 1/2 tsp soda	Slightly less tang
Sugar rolling	Colored sanding sugar	Holiday mode
Plain	Frosted: 2 cups powdered sugar + 3 tbsp butter + 2 tbsp milk + food coloring	The pink grocery-store cookie of memory

Storage & Reheating

Airtight at room temp 5 days — the sour cream keeps them soft longer than standard cookies. The sandwich-bread-in-the-container trick extends it further.

Dough balls freeze 3 months (bake from frozen plus 2 minutes); frosted cookies freeze in single layers once the frosting sets.

Frequently Asked Questions

Why cream of tartar in sugar cookies?

It tenderizes the crumb and adds the faint tang that separates a soft sugar cookie from a bland one — the same acid that makes snickerdoodles taste like snickerdoodles.

Why did mine come out dense instead of pillowy?

Under-creamed butter or over-measured flour. Beat the butter and sugar the full 2–3 minutes (it should lighten in color), and spoon-and-level the flour instead of scooping.

How do I know when they're done with no browning to judge by?

The tops turn from shiny to matte and spring back faintly when tapped — usually 11 minutes. Any golden color on top means the next batch gets one minute less.

Can I roll and cut these into shapes?

This dough is too soft for cutouts — it's a drop cookie by design. For shapes, you want a stiffer rolled dough with no leavening; different tool, different job.
