# Components:
→ Dough
01 - 2 1/2 cups all-purpose flour
02 - 3/4 teaspoon baking powder
03 - 1/4 teaspoon salt
04 - 1 cup unsalted butter, softened
05 - 1 cup granulated sugar
06 - 1 large egg
07 - 2 teaspoons pure vanilla extract
→ Coloring and Decoration
08 - Red gel food coloring
09 - Green gel food coloring
10 - 1/3 cup colored sanding sugar (red and green), optional
# Method:
01 - In a medium bowl, whisk together the flour, baking powder, and salt until evenly mixed.
02 - In a large bowl, beat the butter and sugar until light and fluffy, approximately 2 to 3 minutes.
03 - Add the egg and vanilla extract to the creamed mixture, beating until fully combined.
04 - Gradually fold in the flour mixture, mixing just until incorporated to form the dough.
05 - Separate the dough into three equal portions; leave one plain, tint one with red gel coloring, and the other with green until evenly colored.
06 - Roll each dough portion between two sheets of parchment paper into rectangles approximately 9 by 6 inches, matching thickness and size; chill for 20 minutes.
07 - Layer the dough rectangles starting with plain on the bottom, red in the middle, and green on top; trim edges to align precisely.
08 - Roll the stacked dough tightly from the long side into a log, removing parchment as you roll; optionally coat the exterior with colored sanding sugar.
09 - Wrap the log in plastic wrap and chill for at least 2 hours until firm.
10 - Preheat oven to 350°F and line baking sheets with parchment paper.
11 - Slice the chilled log into 1/4-inch rounds and place them 2 inches apart on prepared sheets.
12 - Bake for 9 to 11 minutes until set but not browned; cool on the sheet for 3 minutes, then transfer to a wire rack to cool completely.
