1 cup of softened butter or magarine 1 teaspoon of vanilla
3/4 cup white sugar 3 cups flour
3/4 cup brown sugar 1/2 teaspoon baking soda
2 eggs 1/2 teaspoon salt
Cream butter and sugar; add eggs and vanilla; mix all dry ingredients separately and add to creamed butter and blend well. Divide into four (or more) separate bowls and add food coloring of your choice.
Then you divide each color into two balls - you'll be making two "rainbows."
Next, you roll each color into a long strip between sheets of wax paper.
And stack them one of each color on top of each other. You do this twice so you have two separate stacks.
When they are all stacked you put them in the refrigerator over night.
The next day, you slice them into 1/4" strips.
