Print Recipe


  • 1 box Vanilla cake mix ( or French vanilla or white cake mix)
  • 2 large eggs
  • 1/2 cup melted unsalted butter
  • 2 tsp vanilla extract
  • 1 cup mini semi-sweet chocolate chips
  • 2/3 cup rainbow jimmies (try to use the jimmies as the round sprinkles can bleed color into your bars)


  • Preheat the oven to 350 degrees. Spray a 13x9 inch glass pan very well with a non-stick spray.
  • In a large mixing bowl, add the cake mix, eggs, melted butter and vanilla. Mix well with an electric mixer.
  • Add in the mini chocolate chips and sprinkles and mix well with spoon or rubber spatula. Batter will be very thick.
  • Spread batter into prepared pan. Use a rubber spatula or spoon to press the batter evenly in the pan. (It helps to spray your spoon or spatula with non-stick spray, so it doesn't stick to the batter.)
  • Bake at 350 degrees for approximately 20-25 minutes until the edges are golden brown.
  • Cool the bars completely in the pan, on a cooling rack at room temperature. Make sure to let the bars cool completely before cutting, or you'll have a mess.


This cake will keep for almost a week covered well on the counter. It's not necessary to keep it refrigerated.
