Cake Batter

• Preheat oven to 350 degrees. Line a 9x13 pan with parchment paper and spray with non-stick cooking spray
• Mix together cake mix, butter, and egg with an electric mixer until a thick dough forms. This will take 5-10 minutes. Scrape down the sides periodically. If you do not have a mixer, you can mix by hand.
• Add sprinkles and stir until incorporated
  
• Press 1/2 or a little bit more of the dough into the bottom of the pan
  
• Pour about half of the can of sweetened condensed milk over the top of the dough leaving a small border. Sprinkle with white chocolate chipes.
  
• Drop small pinches/balls of remaining dough on top of stuffing. Press and flatten. Try to seal the stuffing into the dough.
  
• Bake for 20-25 minutes or until they just begin to brown, a toothpick comes out clean.
• Cool completely before slicing.
