  • 1 pouch sugar cookie mix
  • 1 box white cake mix
  • 3 large eggs
  • 1 cup melted butter salted
  • 1 tsp vanilla extract
  • 3 TBSP rainbow sprinkles
  • 1 can white/vanilla frosting


  1. Heat oven to 350 degrees. Spray a 9x13 baking dish with cooking spray or line it with parchment paper. Set aside.

  2. In large mixing bowl, combine the dry sugar cookie mix, dry cake mix, eggs, melted butter, and vanilla extract. Beat with a handheld blender until combined for about 1 minute.

  3. Add in the sprinkles and very gently (so the colors don't bleed) stir in the sprinkles using a wooden spoon or spatula.

  4. Dump the batter into the prepared baking dish and spread out evenly. Use your hands to help spread it out.

  5. Cook for 30-32 minutes. Edges will be golden brown and puffier than the rest of the bars. The center will look done and a toothpick inserted into the middle should come out clean. Let cool completely for about 1 hour in the pan.

  6. Spread the frosting over the cooled cookie bars. Sprinkle some additional sprinkles over top the frosting.

  7. Cut into bars into squares right away and serve!
