Prepare Dough: In a medium mixing bowl, whisk together the flour, baking powder, and salt. In a larger bowl, cream the butter and sugar until light and fluffy. Beat in the egg, vanilla extract, and peppermint extract, then gradually mix in the dry ingredients.

Color Dough: Divide the prepared dough into two halves. Keep one half plain and color the other with red gel food coloring.

Chill the Dough: Wrap each half in plastic wrap and chill for at least 30 minutes.

Roll Out: Flour a surface and roll out each dough half into rectangles. Aim for an even thickness.

Layer and Roll: Stack the red dough on the plain dough, roll tightly into a log, and chill for 2 hours.

Bake Cookies: Preheat the oven, slice the log into rounds, place onto baking sheets, and bake for 8-10 minutes.
