Preparation Steps

• In a bowl, whisk together flour, baking powder, and salt. Set aside.
• In a large bowl, cream together butter and sugar until light and fluffy. Beat in vanilla extract and egg.
• Gradually add flour mixture to the butter mixture, mixing until just combined.
• Divide dough in half. Tint one half with red food coloring.
• Roll out each dough half between sheets of parchment paper into rectangles. Layer one dough on top of the other, then roll tightly into a log.
• Chill the dough log for at least 1 hour.
• Preheat oven to 350°F (175°C). Slice chilled dough into 1/4-inch thick slices and arrange on baking sheets.
• Bake in preheated oven for 10 minutes, or until edges are golden. Let cool on a wire rack.
