Step 1

In a small bowl, whisk flour, baking powder, and salt together

Step 2

In a larger mixing bowl, beat butter and sugar together until light

Step 3

Beat in egg, vanilla, and milk

Step 4

Add flour mixture, and beat until smooth

Step 5

separate the cookie dough into thirds

Step 6

Add about ½ an ounce of Wilton no-taste red food coloring to one third, and 20-30 drops of liquid blue, or ¼ ounce of Wilton blue gel color to another third and stir them until well combined. In order to make the cookie dough truly red, you need to add quite a big of food coloring, so if the dough seems thinner than it was, go ahead and add 1-2 tablespoons more of flour. You need a dough that will roll out well.

Step 7

Roll each third of dough on a lightly floured piece of parchment paper to aout ⅜ inch thick, and 8x12 inches

Step 8

Refrigerate dough for 30 minutes

Step 9

Preheat oven to 325º

Step 10

Remove cookie dough from refrigerator

Step 11

Lay one sheet on your work surface, and flip a second sheet on top, peeling off the parchment paper. Repeat with the third sheet.

Step 12

Roll cookie dough as tightly as possible so there are no gaps between the layers, making a 12 (or so) inch long log

Step 13

Use floss to cut ⅓-½ inch thick cookies. You can use a knife, but it will flatten the bottom side of the cookie.

Step 14

Place cookies on a baking sheet, and bake about ten minutes, until cookies are set, but not browned.

Step 15

Remove from oven, and let cool
