Next, use food coloring to dye the dough. I use Wilton gel food coloring.
I wrapped my three different colors of dough back in the plastic wrap and chilled them in the refrigerator again for about 1 hour. Next, roll out the dough using a rolling pin into a rectangle shape. I like to put the dough in between two pieces of plastic wrap to roll out dough. That way you don’t need any flour all over your counter. I like less clean up at the end!
They will all look somewhat like this.
Next, you are going to be layering the three colors on top of each other. Brush the first piece of dough (red) with a little bit of egg whites. We use egg whites as glue to keep the three layers together. (I do not have a brush, so you will notice in the picture that I am using the back of a spoon to put the egg whites on the dough)
Then, place the second color (white) on top of the first.
Brush the white dough with the egg whites and place the third color (green in this case) on top.
Take a sharp knife and cut the dough into 1/4 inch thick strips. You may want to use a ruler at this point, so that each slice is exactly the same.
Alternate the strips in the design that you want. I alternated red/green on the top. Mine looks like this.
Wrap it up in the plastic wrap again and chill for another hour. Remove from the refrigerator and slice into cookies.
Take the cookies out of the oven before they have browned. The should not have any brown on them. Cooking time may vary depending on your oven.
Please watch the cookies.
And they will look something like this! Very festive and colorful! You can use any colors you want for any holiday, school colors or team colors!
