The spiral in these cookies is not decoration applied at the end. It is built into the dough: two rectangles, one tinted red and one left plain, stacked and rolled into a log so that every slice off that log carries the same pattern.
That makes the rolling stage the one that matters. Get the two sheets the same size and rolled tightly together, and thirty-six cookies come off the log looking identical.
Why This Recipe Works
- Rolling each dough half to the same 9x12-inch rectangle means the two colours meet edge to edge, so the spiral has no gap running through it.
- Fifteen minutes in the freezer firms the log enough to cut clean quarter-inch rounds instead of squashing the spiral flat under the knife.
- Baking only until the edges are set and nothing has browned keeps the plain dough white, which is the entire point of a two-colour cookie.
- Peppermint extract carries the flavour through the dough while the crushed candy canes stay on the outside, so the texture contrast survives baking.
Ingredient Notes
- Red gel food colouring
- Gel rather than liquid, about half a teaspoon. Liquid colouring at the volume needed for a vibrant shade would loosen the dough.
- Peppermint extract
- Three-quarters of a teaspoon against a teaspoon and a half of vanilla — the recipe keeps peppermint as the smaller of the two.
- Crushed candy canes
- Marked optional and used on the edges of the sliced rounds, not mixed into the dough.
How to Make It
Mix the dry, then cream the butter and sugar
Whisk the flour, baking powder and salt together and set aside. Beat the butter and sugar on medium-high for 2 to 3 minutes until light and fluffy, then beat in the egg, egg yolk, vanilla and peppermint extract.
Bring the dough together
Add the dry ingredients on low and mix just until a soft dough forms. If it looks slightly dry, the tablespoon of milk goes in here.
Tint half
Divide the dough in two. Tint one half with red gel colouring until vibrant and leave the other plain.
Roll two matching rectangles
Roll each half between parchment into a 9x12-inch rectangle about a quarter-inch thick. If either turns sticky, chill the rectangle before going on.
Stack and roll into a log
Peel off the top parchment, lay the red rectangle over the plain one and line up the edges, then pass the pin over gently to fuse them. Starting from a long side, roll into a tight log using the parchment to guide it.
Freeze until firm
Wrap the log and freeze it for 15 minutes so it holds its shape under the knife.
Slice and bake
Heat the oven to 350F (175C) and line your sheets. Slice quarter-inch rounds with a sharp knife, rolling the edges in crushed candy cane if you are using it, and bake 9 to 11 minutes until set at the edges but not browned.
Cool, then drizzle
Cool 5 minutes on the sheet before moving to a rack. Once fully cool, the optional white chocolate drizzle goes on and is left to set before storing.
Building the Spiral
Eleven steps, but they group into four jobs — and only the third one is difficult to redo once it has gone wrong.
Stage 1 of 4
Two doughs from one
Steps 1–4 of 8
Dry whisked, butter and sugar creamed, eggs and both extracts beaten in, then the dough divided and half of it tinted red.
- Mix the dry, then cream the butter and sugarWhisk the flour, baking powder and salt together and set aside. Beat the butter and sugar on medium-high for 2 to 3 minutes until light and fluffy, then beat in the egg, egg yolk, vanilla and peppermint extract.
- Bring the dough togetherAdd the dry ingredients on low and mix just until a soft dough forms. If it looks slightly dry, the tablespoon of milk goes in here.
- Tint halfDivide the dough in two. Tint one half with red gel colouring until vibrant and leave the other plain.
- Roll two matching rectanglesRoll each half between parchment into a 9x12-inch rectangle about a quarter-inch thick. If either turns sticky, chill the rectangle before going on.
Stage 2 of 4
Two matching sheets
Steps 5–5 of 8
Each half rolled between parchment to the same 9x12 inches and quarter-inch thickness. Matching sizes are what close the spiral.
- Stack and roll into a logPeel off the top parchment, lay the red rectangle over the plain one and line up the edges, then pass the pin over gently to fuse them. Starting from a long side, roll into a tight log using the parchment to guide it.
Stage 3 of 4
Stack, roll, freeze
Steps 6–7 of 8
Red laid over plain, edges aligned, fused with a light pass of the pin, rolled tight from a long side and frozen 15 minutes.
- Freeze until firmWrap the log and freeze it for 15 minutes so it holds its shape under the knife.
- Slice and bakeHeat the oven to 350F (175C) and line your sheets. Slice quarter-inch rounds with a sharp knife, rolling the edges in crushed candy cane if you are using it, and bake 9 to 11 minutes until set at the edges but not browned.
Stage 4 of 4
Slice and bake
Steps 8–11 of 8
Quarter-inch rounds, optional candy-cane edges, 9 to 11 minutes at 350F to set but not brown, then cooled and optionally drizzled.
- Cool, then drizzleCool 5 minutes on the sheet before moving to a rack. Once fully cool, the optional white chocolate drizzle goes on and is left to set before storing.
Success Tips
- If the rectangles will not line up neatly, trim them square before stacking rather than stretching one to fit — a stretched sheet springs back and distorts the spiral.
- A sharp knife and a quarter-turn of the log between cuts keeps the rounds circular instead of flattening one side.
- Pull the sheet while the plain dough is still white; browning is the one thing that cannot be undone on a two-colour cookie.
Serving Ideas
Thirty-six cookies off one log makes this a tray for a holiday table or a tin.
Frequently Asked Questions
What if the dough is too sticky to roll?
Chill the rolled rectangle before stacking. The recipe builds this in as an option at the rolling stage.
Why freeze the log before slicing?
Fifteen minutes in the freezer firms it enough to cut clean quarter-inch rounds. A soft log squashes and the spiral flattens.
Are the candy canes necessary?
No. Both the crushed candy cane edges and the white chocolate drizzle are marked optional in the recipe.
