Description

You only need two ingredients (aside from water) for this Halloween Brain Jello mold. It’s a sweet and spooky jiggly conversation piece.


Ingredients

Scale
  • 1 cup boiling water
  • 3 oz green Jello
  • 1 cup cold water
  • 2 cups (5oz) frozen whipped topping
  • nonstick cooking spray

Instructions

  • Add 3oz of Jell-O mix to 1 cup of boiling water and stir until it’s dissolved.
  • Then add 1 cup of cold water to the jello mixture and refrigerate for 1 hour. You want it to cool and thicken slightly, but still be pourable for the next step.
  • Add 2 cups of defrosted Cool Whip into a large bowl then pour the chilled Jell-O in slowly and gradually, whisking continually as you add it to the whip. This will help to ensure a smooth texture, otherwise, the Cool Whip and Jello will separate and you’ll end up with a kinda speckled final dessert.
  • Spray the silicone brain mold with non-stick cooking spray so that your brain comes out clean after it’s set.
  • Then pour the gelatin mix into the mold and pop it in the fridge at least 4 hours until the Jello is set.
  • Once the Jello is set, run a knife around the edge of mold before then placing a serving plate on top of the mold, turning the whole thing upside down. The brain should release and be ready to serve.
  • If you’re not ready to serve it right away, cover the brain in plastic wrap and keep chilled in the refrigerator up to two days.
