Step 1

In a large bowl, mix together butter and sugar until light and fluffy.

Mix in flour.

Step 4

Make the dough into a ball and cut into two halves.

Step 5

Add food coloring to one half of the dough, working it in until evenly mixed.

Step 6

On a large cutting board covered in plastic wrap, use a rolling pin to roll out each piece of dough to make two 12x9-inch (30x22-cm) rectangles. Tip: Place wax paper over the dough while rolling to keep the dough from sticking to the rolling pin.

Step 7

Take the colored dough rectangle and place it over the other regular dough rectangle.

Step 8

Use the plastic wrap under the regular dough rectangle to help you roll the two rectangles up.

Step 9

Fill a flat dish or baking pan with sprinkles. Roll the dough around it until the outside is completely coated.

Chill for at least 4 hours.

Step 11

Preheat the oven to 375°F (190°C).
