Ingredients Nutrition

  • 1 (18 ounce) box French vanilla cake mix (I use Betty Crocker super moist or Duncan Hines)
  • 2 cups butter (or 1 cup butter and 1 cup margarine) or 2 cups margarine, melted and cooled (or 1 cup butter and 1 cup margarine)
  • 2 cups sugar
  • 2 teaspoons vanilla
  • 1 12 cups brown sugar, packed
  • 6 eggs
  • 1 12 cups sifted cocoa powder
  • 2 cups flour
  • 12 teaspoon baking soda
  • 12 teaspoon salt
  • 1 12 cups semi-sweet chocolate chips


  1. Set oven to 350 degrees.
  2. Grease a 13 x 9-inch baking pan, and line bottom with parchment paper.
  3. In a food processor, prepare the cake mix as stated on the box; spoon out into a bowl, do not wash the processor bowl.
  4. For the brownies: using the processor, blend the melted butter, sugars, vanilla and eggs.
  5. In a small bowl, sift together the flour, baking soda and salt; blend/PULSE with the processor until combined (do not add in the chocolate chips, they are placed on top).
  6. Pour the batter into prepared baking pan.
  7. Spoon/dollup the cake mix batter on top of the chocolate batter, and swirl in gently with a knife (just a bit, do not swirl too much!).
  8. Bake for 35-45 minutes, or until the brownie part seems to be done, and the cake has risen, but is not getting too browned.
  9. Remove from oven and sprinkle chocolate chips over top while cake is hot.
  10. Let stand for 6-8 minutes, the spread with a knife.
