Chocolate-and-vanilla sugar cookies with a clear dark spiral through every buttery slice.
The important detail in this recipe is the way the dough is shaped and finished. Layer 8 × 14-inch chocolate and vanilla rectangles and roll from the long edge. Chill the spiral log, then cut ½-inch slices; never roll the doughs together into a marble.
Before mixing, measure the flour without packing it and prepare the pans. Press the two dough layers together gently before rolling. Roll tightly using parchment for support, sealing small cracks as you go. An air pocket becomes a hole in the baked spiral.
Watch the first tray closely near the end of the baking range. Let the crumb set on the pan before lifting the cookies, then store only after they have cooled.

Ingredients
Scale ingredients and US equivalents, including eggs; weigh beaten egg for fractional batches. Keep piece size, thickness, oven temperature and baking time per tray unchanged. Extra trays increase whole-batch time.

Instructions
Mixing
- Make the doughWhisk flour, baking powder and salt. Cream butter and sugar, mix in egg, yolk and vanilla, then add dry ingredients on low until uniform. Keep cocoa and milk separate until dividing the dough.
Thermal management
- Manage the doughDivide the dough in half. Mix cocoa and milk into one half. Shape both halves into 4 × 5-inch blocks, wrap and chill 60 minutes, until less sticky but still bendable.
Shaping
- Shape evenlyOn separate parchment sheets, roll each dough into an 8 × 14-inch rectangle. Lay chocolate on vanilla, pat out air pockets, and roll tightly from a long edge into a 14-inch log. Cut in half, wrap both 7-inch logs, and chill 2 more hours. Slice each into fourteen ½-inch rounds and place 2 inches apart.
Baking
- Bake one tray at a timePreheat to 350°F (175°C). Bake on the center rack for 14–15 minutes. Edges should be set and only lightly colored; centers must lose their wet sheen. Use cool pans for subsequent trays.
Cooling
- Let the crumb setRest on the baking sheet for 5 minutes, then move to a rack. Allow about 20 minutes total cooling before storing; the center firms as steam escapes.
Chef’s Science & Pro Tips
Remove trapped air
Press the two dough layers together gently before rolling. Roll tightly using parchment for support, sealing small cracks as you go. An air pocket becomes a hole in the baked spiral.
Keep the portion consistent
Layer 8 × 14-inch chocolate and vanilla rectangles and roll from the long edge. Chill the spiral log, then cut ½-inch slices; never roll the doughs together into a marble. Different thicknesses need different baking times; bake comparable pieces together.
Roll while pliable
Over-chilled dough can crack instead of bend. Let the first chilled blocks soften just enough to roll. Patch small cracks with your fingers while making the spiral; then chill the completed logs fully so the slices stay round.
Storage & Make-Ahead
| Method | How long | What to do |
|---|---|---|
| Room temperature | 3–4 days | Cool completely and seal in an airtight container. Keep unfrosted cookies separate from moist or strongly flavored treats. |
| Refrigeration | Raw dough: up to 2 days | Cover raw dough tightly. Refrigerating plain baked cookies is unnecessary and can dry them; let chilled dough become workable before shaping. |
| Freeze raw | Up to 2 months | Freeze the wrapped spiral logs up to 2 months. Thaw overnight in the refrigerator until sliceable, then cut ½-inch rounds and bake. Do not flatten or scoop this dough. |
| Freeze baked | Up to 2 months | Freeze fully cooled, plain cookies in a sealed container with parchment between layers. |
| Restore | 30–60 minutes | Thaw baked cookies in their closed container at room temperature. For a freshly warmed plain cookie, use a 300°F oven for 2–3 minutes; cool briefly before serving. |
Notes
- Use the gram weights for the most consistent dough. Small leavener weights are approximate; measure teaspoons carefully. Egg weights exclude shells. Oven temperatures refer to a conventional oven.
Nutrition
Approximate nutrition per serving calculated from ingredient weights divided by 28. Includes required fillings and toppings, excludes optional decoration and unused rolling flour. Brands and actual portion sizes change the estimate.

What texture should these cookies have?
Chocolate-and-vanilla sugar cookies with a clear dark spiral through every buttery slice. Judge the final texture after cooling, not while the centers are warm.
Why are there gaps in the spiral?

Why does the vanilla layer crack?
Over-chilled dough can crack instead of bend. Let the first chilled blocks soften just enough to roll. Patch small cracks with your fingers while making the spiral; then chill the completed logs fully so the slices stay round.
