Patti Cakes

Fudge Marble Patti Cakes 
Makes about nine 4" cookies (you'll yield more cookies if you make them smaller)

1 package (18.25 oz) Duncan Hines Fudge Marble Cake Mix
1 large egg
1/3 cup vegetable oil
4 tbsp water, divided
1 cup chocolate chips (optional)

Preheat oven to 350 degrees.
Remove chocolate packet from cake mix box. 
Combine dry cake mix, egg, oil and 3 Tbsp. water in large mixer bowl. Beat until smooth. 
In a small bowl mix chocolate packet and 1 tbsp water until thoroughly combined.  Add about 2/3 cup of the yellow cake batter dough to the chocolate mixture.  
Mix the chocolate chips, if using, to the yellow dough thoroughly and then lightly swirl in the chocolate dough.  Don't over mix here because you want to keep the marbling effect! 
With a #20 ice cream scoop (or 1/3 cup measure) drop the cookie batter on to parchment lined baking sheets.  Bake for about 14 minutes, rotating baking sheets at the halfway point.  Cookies should be light brown around the edges.  Let cool completely on the baking sheet.
