  • 1 box Pillsbury™ Yellow Moist Supreme Cake Mix
  • 1 box Pillsbuury™ Chocolate Fudge Brownie Mix
  • 2/3 cup olive oil halved
  • 4 large eggs
  • 1/2 cup chocolate chips


  • Heat the oven to 350. 
  • Prepare (1) 9 x 13 and (1) 8 x 8 baking dishes and set them aside.
  • In a medium mixing bowl, add 2 eggs, 1/3 cup olive oil, and cake mix. Mix well. Add in the chocolate chips.
  • In a separate mixing bowl add 2 eggs, 1/3 cup olive oil, and brownie mix. Mix well.
  • Take half of the cake mixture and half of the brownie mixture and swirl them together in the baking dish. Both mixtures will be thick but be patient and mix them well. Do this for both dishes.
  • Place in the oven for 20-25 minutes or until fully cooked. 
  • Allow to cool slightly before cutting and serving.
