Instructions

To Make the Cookies

1. Cream butter and sugar for 3-5 minutes until fluffy with a mixer.
2. Add in eggs, sour cream and vanilla and beat well.
3. Mix flour and baking soda together and pour half of mixture into the mixer and beat until combined. Add remaining flour and beat until combined.
4. Divide dough into thirds. Make one portion of dough smaller than the rest. This is the blue dough. Return the dough to the mixing bowl and add blue food coloring. Beat until color is distributed evenly. Wrap tightly in plastic wrap.
5. Rinse the mixing bowl and add another batch of dough and red food coloring. Beat until color is distributed evenly. Wrap tightly in plastic wrap.
6. Wrap the remaining uncolored dough in plastic wrap.
7. Refrigerate all dough for 1 hour.
8. Remove dough from the refrigerator and unwrap the blue dough. Shape into a large rectangle. My rectangle was about 10" long. Wrap tightly with plastic wrap and set aside.
9. Unwrap the red dough. Remove ⅓ of the dough and shape into a thick rectangle. Place on a piece of plastic wrap and fold the wrap over the dough so it's covered on both sides. Use a rolling pin to flatten the dough to about ¼" thick. Gently shape the ends to make them square and make the dough about the same size as the blue rectangle. Repeat with the uncolored dough.
10. Divide the remaining red dough in half and shape it into a large rectangle and place it on plastic wrap. Fold the plastic wrap in half and use a rolling pin to shape the dough into a ¼" rectangle that is the same width as 2 blue rectangles. Repeat so you have two red strips.
11. Do the same with the uncolored dough. (Now, you'll probably have left over dough, and that's okay, just shape into a rectangle, slice and bake and enjoy with a cup of coffee)

Assemble the Dough

1. Place the blue dough on a large piece of plastic wrap. Place smaller red rectangle right next to the blue. Press the two together gently to remove any gaps.
2. Place the small uncolored dough onto the red and press together to remove any gaps. The red and uncolored dough should be about the same size as the blue rectangle.
3. Place one of the large red pieces of dough onto the top of the dough. Gently press to firmly hold together. Repeat with the white and follow with the remaining red dough.
4. Continue to shape the dough into a large rectangle. Wrap firmly with plastic wrap and refrigerate for 1-2 hours.

To Bake Cookies

1. Preheat oven to 375. Line a baking sheet with parchment paper.
2. Remove dough from the refrigerator and unwrap. Use a sharp knife to slice the dough into ¼" slices. Trim the ends of the dough if necessary. Place cookie onto prepared pan and bake for 6-7 minutes or until the cookies begin to brown.
3. Remove from oven, let cool on baking sheet for 2 minutes. Move to a cooling rack and until cooled completely.
4. Store in an airtight container until ready to eat.
