Method
- Beat the butter and sugar until smooth: Place the 1 cup (226 g) softened unsalted butter and 1 cup (120 g) powdered sugar in a large mixing bowl.
- Beat with an electric mixer on medium speed for about 2–3 minutes, until the mixture looks smooth, creamy, and slightly lighter in color.
- Avoid excessive whipping: Too much incorporated air can encourage the cookies to puff and distort their spiral shape.
- Add the egg and vanilla: Add the 1 large egg (about 50 g without shell) and 2 teaspoons (10 ml) pure vanilla extract.
- Mix on low to medium speed until incorporated, scraping down the sides of the bowl as needed.
- The mixture should look creamy and mostly uniform: A slightly curdled appearance at this stage is not necessarily a problem; it should come together when the flour is added.
- Incorporate the dry ingredients: Add the 2 3/4 cups (330 g) all-purpose flour and 1/2 teaspoon (about 3 g) fine salt.
- Mix on low speed just until the flour disappears and a soft dough forms.
- The dough should feel pliable and slightly firm rather than wet or sticky. If it looks crumbly, gently press a small amount together with your fingers. It should hold its shape without falling apart.
- Avoid prolonged mixing, which can make the cookies tougher.
- Divide and color the dough: Divide the dough into three equal portions.
- Leave one portion uncolored to create the natural vanilla layer.
- Place the second portion in a separate bowl and work in 1/4 teaspoon (about 1 ml) red gel food coloring until the color is evenly distributed.
- Add 1/4 teaspoon (about 1 ml) green gel food coloring to the third portion and mix until uniform.
- Use gentle folding and pressing motions rather than vigorous kneading. The dough should remain smooth and cohesive without becoming greasy.
- Roll out the three dough layers: Place the uncolored dough between sheets of parchment paper and roll it into a rectangle approximately 8 × 10 inches (20 × 25 cm).
- Aim for an even thickness of about 1/8 inch (3 mm).
- Repeat with the red and green dough portions, creating rectangles of similar dimensions.
- If the dough becomes too soft to lift or begins sticking to the parchment, refrigerate it briefly until it firms up.
- Stack the colored layers: Remove the upper sheet of parchment from each dough rectangle.
- Place the green dough on the work surface with its parchment underneath. Carefully invert the uncolored dough over the green layer, then peel away its parchment.
- Position the red dough on top and remove its parchment.
- Gently roll over the stacked layers with the rolling pin to help them adhere.
- The layers should look flat and even, with minimal air trapped between them.
- Roll the dough into a spiral: Starting from one of the 8-inch (20 cm) sides, roll the stacked dough into a tight log, using the bottom parchment sheet to help lift and guide the dough.
- Keep the roll snug without squeezing so hard that the colored layers smear together.
- If small cracks appear along the outside, gently press them closed as you roll.
- The finished log should be approximately 8 inches (20 cm) long, with a clearly visible red, green, and vanilla spiral at each end.
- Chill the cookie dough: Wrap the log tightly in plastic wrap and refrigerate for 2 hours, or until firm enough to slice without flattening.
- For a rounder shape, gently rotate the wrapped log occasionally during the early part of chilling.
- The dough should feel firm when pressed but not frozen solid.
- Preheat the oven and prepare the baking sheets
- Preheat the oven to 350°F (175°C). Line two 13 × 18-inch (33 × 46 cm) rimmed baking sheets with parchment paper.
- Position an oven rack in the center of the oven. Baking one sheet at a time helps promote even browning.
- Slice the swirl cookies: Unwrap the chilled dough and place it on a cutting board.
- Using a sharp, thin-bladed knife, cut the log into approximately 1/4-inch (6 mm) thick slices.
- Arrange the slices on the prepared baking sheets, leaving approximately 1 1/2 inches (4 cm) between cookies.
- The batch should yield approximately 30 cookies, depending on the final log dimensions and slice thickness.
- If a slice becomes slightly oval, gently reshape it with your fingers. If the dough starts to smear or flatten while slicing, return the log to the refrigerator until firm.
- Bake until the edges are lightly golden: Bake at 350°F (175°C) for approximately 12 minutes per batch, until the cookies look set and the bottom edges are just beginning to turn pale golden.
- The tops should remain mostly light in color, and the red and green spirals should still look distinct.
- Avoid waiting for deep golden tops: Excessive browning can dull the holiday colors and make the cookies dry.
- Because ovens vary, watch the visual cues closely toward the end of baking.
- Cool before serving: Allow the cookies to rest on their baking sheet for 5 minutes.
- Transfer them carefully to a wire rack and let them cool completely for approximately 25 minutes.
- The cookies will become firmer as they cool, developing lightly crisp edges while retaining a tender center.
- Once completely cooled, arrange them on a Christmas cookie platter or pack them into airtight gift containers.
Notes
Chilling the rolled dough before slicing helps keep the spirals neat and prevents excessive spreading during baking.
