  • 1-1/2 sticks butter, softened
  • 1/2 cup white sugar
  • 1 tsp vanilla
  • 1/4 teaspoon salt
  • 1-1/2 cups flour
  • Food Coloring – We used Americolor Soft Gel Paste in the following Colors:
    103 Sky Blue
    111 Leaf Green
    107 Lemon Yellow
    114 Deep Pink
    122 Violet

Heat oven to 300 and line a square baking pan with aluminum foil. Spray the foil with cooking spray. Set aside.

In a mixing bowl, add butter, sugar, salt and flour. Mix well. The dough will be stiff and take a bit to come together. Don’t give up. Use the back of a spoon to mix the butter into the flour.

Evenly divide the dough into 5 separate bowls and add food coloring to each bowl. Using the back of a spoon, mix the food coloring into the dough well. If necessary, use your hands, but beware you may want to wear gloves as the color may stain your skin.

Once all five colors of dough are blended well, divide each color into four sections.

Rainbow Cookie Bar Dough

Roll each section into a “thick snake” and place into the prepared pan in a rainbow pattern. There’s no right or wrong way to do this, so let the kids help with this part. It’s like playing with playdough, but you get to eat it afterwards. Too fun!

Once all the dough is in the pan, use your fingers to press it together and evenly into the pan.

  1. How many grams or ounces are in one stick of butter as it would be good if you gave the weights as we do not have sticks of butter in australia

  2. I made these today with my little girl. So much fun!! One stick of butter=1/2 cup. We didn’t have a square pan so we used a small round one and cut them like slices of pizza.
