These cookies come from one dough, not two. You make a plain butter dough, cut it in half, tint one half red, then stack and roll the two into a log. Slice the cold log and you get a spiral in every cookie.
The number that matters most is four. The rolled log needs at least 4 hours in the fridge before you cut it. Skip that and the slices smear, the spiral blurs, and the cookies spread into flat discs. Cold dough cuts clean.
You need 8 tablespoons of soft butter, 1 cup of sugar, 1 egg, 1 1/2 cups of flour, and a half teaspoon each of salt and vanilla. The red coloring is a half teaspoon, and the sprinkles go on the outside only.
Step-by-Step Instructions
1. Cream butter and sugar
Beat the soft butter with the sugar until the mixture looks pale and fluffy. Scrape down the bowl once so no dry sugar hides at the bottom.
2. Add egg, vanilla, salt
Beat in the egg, vanilla, and salt until smooth. If the mix looks grainy or split, it was too cold. Let it sit 5 minutes and beat again.
3. Mix in the flour
Add the flour and mix just until it disappears. Stop there. You should have a soft dough that pulls away from the bowl.
4. Split the dough
Shape the dough into a ball and cut it into two equal halves. Weigh them if you want the swirl even.
5. Tint one half
Work the red coloring into one half with your hands or a spatula until the color is even. Wear gloves if you do not want red fingers.
6. Roll two rectangles
Set each half on plastic wrap and roll it into a 12×9-inch rectangle, about a quarter inch thick. Lay wax paper over the dough so the pin does not stick.
7. Stack the rectangles
Lift the red rectangle and lay it on top of the plain one, lining up the edges. Press down gently so they hold together.
8. Roll into a log
Use the plastic wrap under the bottom rectangle to help you roll the two layers up from a long side. Keep it tight, with no air pockets.
9. Coat in sprinkles
Pour sprinkles into a flat dish or pan. Roll the log through them until the outside is covered all the way around.
10. Chill at least 4 hours
Wrap the log and refrigerate for at least 4 hours. Overnight works too, and cold dough is what gives you clean slices.
11. Heat the oven and slice
Heat the oven to 375°F (190°C). Cut the cold log into 1/4-inch slices and set them on a cookie sheet, about an inch apart.
12. Bake 8 to 10 minutes
Bake until the edges are blonde, 8 to 10 minutes. Let them sit on the sheet for 2 minutes, then move them to a rack to cool.
Tips & Tricks
- Roll the dough between two sheets of wax paper or plastic wrap so it does not stick to the pin.
- Chill the log at least 4 hours. Overnight is fine and makes slicing easier.
- Cut straight down with a sharp knife. A sawing motion drags the spiral out of shape.
- Bake until the edges are blonde, not brown. The white part of the swirl shows doneness better than the red.
Variations
Green and red
tint one half green and leave the other plain for a holiday look.
Chocolate half
swap 2 tablespoons of the flour in one half for cocoa powder for a brown and white swirl.
No sprinkles
leave the log bare and press coarse sugar on the outside instead.
How to Store Sugar Swirl Cookies
Refrigerator
Keep baked cookies in a sealed container at room temperature for up to a week. The unbaked log keeps in the fridge for 3 days, wrapped tight.
Freezer
Freeze the unbaked log wrapped in plastic and foil for up to 2 months. Slice it while still frozen and add 1 to 2 minutes to the bake time. Baked cookies freeze for 2 months.
Reheating
No need to reheat. If you want them warm, 3 minutes in a 300°F oven brings back the fresh texture.
Frequently Asked Questions
Q: Why did my swirls disappear in the oven?
The dough was too warm or the slices were too thin. Chill the log the full 4 hours, cut them a full quarter inch thick, and put the sheet back in the fridge for 10 minutes before baking.
Q: Can I skip the 4 hours of chilling?
No. Warm dough squashes when you cut it and the spiral smears. If you are short on time, put the log in the freezer for 45 minutes, but the fridge is more even.
Q: How do I know the cookies are done?
Look at the pale part of the swirl. When the edges turn light blonde and the center still looks soft, pull them. They firm up as they cool.
Q: Can I use liquid food coloring instead of gel?
Yes, but you may need more than a half teaspoon to get a strong red, and the extra liquid softens the dough. Add a spoonful of flour if it gets sticky.
Q: Why are my cookies dry?
Usually too much flour or too long in the oven. Spoon the flour into the cup and level it, and take the cookies out at 8 minutes the first time you make them.
