Ingredients
Equipment
Method
- Whisk the flour, baking powder, and salt together in a medium bowl.
- Beat the butter and sugar in a large bowl until light and fluffy, about 2 minutes.
- Beat in the egg and vanilla.
- Mix in the flour mixture just until combined.
- Divide the dough in half and tint one half red and the other half green.
- Roll each half between sheets of parchment into a 9x6-inch rectangle.
- Chill the rectangles until firm but still pliable, 15 to 20 minutes.
- Stack the dough rectangles and peel away the top parchment.
- Roll tightly from a 6-inch edge into a 9-inch log.
- Wrap the log and chill until firm, at least 2 hours.
- Heat the oven to 350°F.
- Line a large baking sheet with parchment.
- Slice the log into 1/4-inch rounds and place them about 1 1/2 inches apart.
- Bake in batches for 10 to 12 minutes, until set with just barely golden edges.
- Cool the baking sheet completely between batches.
- Let the cookies rest on the baking sheet for 5 minutes.
- Transfer the cookies to a wire rack to cool completely.
Notes
For neater spirals, chill the log until firm before slicing. Store in an airtight container at room temperature for up to 5 days; freeze baked cookies for up to 2 months. For a dairy-free option, use a 1:1 plant-based butter stick.
