Next, I roll each dough portion between two sheets of parchment paper. This step is crucial—it prevents sticking and gives you even layers. I roll each color into a neat rectangle, all roughly the same size. Once the layers are rolled, I gently stack them on top of each other: green on the bottom, red in the middle, and white on top. I take my time lining up the edges, and if something overlaps, I trim it for cleaner spirals later.
Now comes the fun part: rolling the dough into a log. I start from the long side and roll slowly but firmly. The parchment paper helps guide the dough so it stays tight. The first time I made these, I rolled too fast and ended up with air pockets that ruined the shape. Now I go slowly, smoothing the dough as I go. Once rolled, the dough log looks like a giant candy cane swirl. I wrap it tightly in plastic wrap and refrigerate it for at least two hours. Honestly, letting it chill overnight works even better.
After the dough is cold and firm, I pour Christmas sprinkles onto a baking sheet and roll the dough log over them. The sprinkles stick beautifully to the cold dough, creating an edge that looks like a holiday confetti explosion. I slice the log into ¼-inch cookies, place them on a baking sheet, and bake until the edges look slightly set. The moment they come out of the oven, the swirls are bold and gorgeous, and I always feel a little proud of how pretty they turn out.
Pro Tips for Best Results
I tested this recipe three different ways, and one of the biggest things I learned is that chilling the dough is non-negotiable. I tried slicing the log after only 30 minutes once, and the dough was too soft—it squished into oval shapes instead of circles. A fully chilled dough makes slicing beautifully precise.
Another tip I learned the hard way: always use gel food coloring. Liquid food dye made the dough sticky, wet, and harder to roll. The gel creates bright colors with just a tiny drop and keeps the dough’s texture perfect. If you add too much gel and the dough softens, just chill it for 15 minutes before rolling.
I also discovered that rolling the dough between parchment paper makes everything easier. I tried rolling on a floured counter once, and the dough absorbed too much flour, making the cookies dry and crumbly. Parchment eliminates the need for excess flour entirely.
Finally, sprinkles stick best when the dough is extra cold. I made the mistake once of letting the log come to room temperature before rolling it in sprinkles, and half of them fell off. Chilling ensures a nice, even rim that bakes in perfectly.
Common Mistakes to Avoid
I made several mistakes when I first experimented with pinwheel cookies, and I want to help you avoid those frustrations. The first mistake was not kneading the flour fully into the dough. The dough ended up too soft and delicate to work with. Make sure it’s fully incorporated before dividing the dough.(See the next page below to continue…)
