Halloween Party Jello Brain

BRAAAAAAIIINNNNNNSSSS!
If you have one of those plastic brain molds from the party store, you’re going to need a good jello recipe to make your edible brain. This is an easy and reliable recipe using Jell-Oยฎ style gelatin.

The zombies are hungry and need some tasty brains to eat. No problem! You just happen to have a brain mold, so you can mix up an edible brain to feed those ravenous undead.

Where Can I Find a Brain Mold for Jello?

Amazon and party supply stores are the best places to find a Halloween jello brain mold. I provided the link for this mold below.

Here is the Amazon link to the type of brain mold I use, pictured above. They have several other styles and sizes of brain molds available. Mine holds about 6 cups.

Ingredients For this Halloween Jello Brain Recipe

You don’t need much to make my Halloween Jello Brain Recipe! See the recipe card for exact measurements.

  • 6-cup Plastic Brain Mold
  • 2 6-ounce Boxes of Jello
  • 12-ounce can Evaporated Milk โ€“ fat-free works best, but I have used 2%
  • Water โ€“ Both boiling and chilled
  • Food Coloring โ€“ optional, but can make interesting results!

Does the Evaporated Milk Need to Be Fat Free?

  • Milk that has fat in it runs a high risk of curdling. That may look interesting, but could interfere with how the gelatin sets up.
  • Having said that, I have used 2% fat evaporated milk without dire consequences, it tasted and looked fine, just some interesting tiny speckles (the blue-grey brain was made with 2%).

Make-Ahead Tip: You can make this ahead a couple days and just keep it in the mold in the fridge, covered with plastic wrap.

How To Make an Edible Jello Brain in a Mold

Making my Halloween Jello Brain Recipe so simple, and it actually does taste good, too!

prepping and spraying brain mold,

Prep Everything

  • Gather your measuring cups, a whisk, and a bowl that will hold the mold.
  • Start your water boiling, and have the cold water ready as well.
  • Wash and dry the mold. Then place it in a bowl for stability.
  • Spray the clean/dry brain mold with cooking spray.

  • Mix the Jello with the boiling water. Whisk until fully dissolved.
  • Whisk in the cold water.
adding evaporated milk to the jello, red & green food coloring added
  • Add the can of evaporated milk and whisk until combined.
  • Add food coloring, if using.
whisking food dye into the jello mixture, mixture in mold
  • Whisk in the food coloring and adjust color as desired.
  • Pour mixture into brain mold (set mold in a bowl to keep it from tipping).
  • My 6-cup mold was not filled to the top, but produced a nice sized brain. I think the zombies will approve.

  • Place in the fridge and chill for at least 2 hours.
  • Remove from fridge, place a plate over the mold and invert it. The brain should easily come out. If not, jiggle it to loosen it, or dip the mold in some warm water briefly to help it loosen. Repeat the plate/invert step.

What is the Best Flavor Jello for a Brain?

The peach flavor gelatin is not only tasty, but it has a light enough color to take on the food dye very well. Especially once mixed with the evaporated milk, which makes it opaque.

I used the Berry Blue Jell-Oยฎ flavor and made the cool grey-blue pictured. I love it! I added 25 drops of red food coloring, and 25 drops of green to get that shade. You can have fun with it!

I Want My Brain to be Grey

Okay. You will get grey with equal parts Red, Green, and Blue food coloring (start with 10 drops of each, and possibly as much as 15 drops of each). You will need to take into account the color of the gelatin you are starting with.

Again, the peach flavor is good for this. If you have an unflavored gelatin, not only will it probably taste like brains, but the color will be easier to control. Though I doubt anyone will eat it, lol!

It can be hard to get grey from Strawberry Jello (in which case I just add lots of red and make a bloody brain!).

    I’ve made your Brain jello twice. first time I used orange jello, was a hit. I made it again tonight using lime jello and the color is awesome. This is fun for the kids and real easy to make.

  2. Casie says:

    Can you omit the โ€œmilkโ€ for the same result?

    1. Sandy says:

      It just won’t be as opaque. You may need to add a little more water or some juice.

  3. Nikki says:

    Hi, do you have any tips for joining two half brain jellies together successfully?

    1. Sandy says:

      Maybe get those extra long toothpicks used for appetizers and stick several in one side, then join them that way?

  4. Allison Higgins says:

    The red brain in the picture…. is it made from peach gelatin?

    1. Sandy says:

      Yes, with some strawberry jello and food coloring.

      1. Laura says:

        Ugh I just bought the ingredients for this. I donโ€™t have strawberry jello

      2. Sandy says:

        Peach jello works great, or any flavor/color. You can add extra food coloring like I did to make it a saturated color.

  5. Amy says:

    Will a can of 2 % work? My store didnโ€™t have fat free, so just thought I would check before going on a hunt!

    1. Sandy says:

      I’m not 100% sure, but if that was all I had, I’d try it. Maybe the curdling will make it look even spookier.

  6. Sherri says:

    Made lime jello brain for my grandsons 5th birthday. Looked awesome. Tasted good. Definately a keeper. 5 stars for ease and looks

    1. Sandy says:

      That’s great! Thank you!

  7. Melissa says:

    How can I make this alcoholic?

    1. Sandy says:

      I haven’t tried it, but maybe replace some of the water with alcohol.

  8. Ildi says:

    Why is the โ€œmilkโ€ has to be fat free?

    1. Sandy says:

      So it doesn’t curdle.

  9. Elizabeth esquivel says:

    This is awesome! When do you at the food coloring?

    1. Sandy says:

      I add the food coloring after adding the can of “milk”. Use peach jello for a flesh colored brain, and cherry or strawberry for a redder brain. Then add the amount of food coloring you want.

    This is awesome! I needed a gelatin brain recipe! Thanks!
