Orange Swirl Bars

1. Mix cake mix, eggs, and oil in a large bowl. Note: You can also use 1/4 C of any of The Olive Bin's first cold-pressed olive oils and 1/4 C Orange olive oil if you prefer a more subtle orange flavor. 
2. Take 1/2 the dough and add 1 tsp orange extract. Add a pinch of orange food coloring. 
3. In a baking pan, alternate dough orange and white. Add one package of vanilla chips to the top and pat down into the batter. 
4. Bake at 350 degrees for 15 minutes. 

If you choose to add icing:

1. In medium bowl, mix powdered sugar and butter with spoon or electric mixer on low speed. Stir in vanilla and 1 tablespoon of the milk.
2. Gradually beat in just enough remaining milk to make frosting smooth and spreadable. If frosting is too thick, beat in more milk, a few drops at a time. If frosting becomes too thin, beat in a small amount of powdered sugar.
