These Jello worms are guaranteed to be an absolutely slimy and gross, but hilarious Halloween hit at your house!

Apparently, Halloween brings out the non-food-snob in me, since this is the first week in three years that has brought me to post a hot dog (cue husband cheering!) and now jello.

I don’t really have anything against the stuff. I ate it nearly nightly growing up and remember loving it, but in my efforts to get away from processed foods, we haven’t enjoyed the jiggly stuff in years.

With the exception of our newfound love of jello worms, that is.

Here’s the premise – you stuff as many bendy-neck straws that have been straightened out into a container that can hold at least 4 cups of liquid.

Pack them in there as tight as can be (see the step-by-step pictures below). Then, pour the jello gently into and over the straws, refrigerate until set, and then delicately squeeze the worms out of the straws.

To say these jello worms were an absolute hit with my kids would be the understatement of the year. They went beserk. Shouting “Look, I’m eating a worm! Aaah!” didn’t get old, even after they had inhaled many, many of these squirmy little worms.

I’ll be perfectly honest. I couldn’t eat them. I tried. One. And I nearly gagged. Texture, cold sliminess, the fact that, except for the detail of my worms being more gray than brown, they really, really looked like worms – all of it culminated in me not being able to stomach the thought.

Which ended up not being a problem because my boys made short work of these decomposers.

If you so choose to make these – may the force be with you. I hope your stomach is a bit stronger than mine.

Jello Worms

4.38 stars (8 ratings)


  • 1 (6-ounce) package purple gelatin/jello
  • 3 envelopes (3/4 ounces) unflavored gelatin
  • 3 cups boiling water
  • ¾ cup whipping cream
  • green food coloring, as needed
  • 100 + plastic straws with bendable necks


  • Choose a container that can hold at least 4 cups of liquid. It should be completely straight all the way up or have a slightly wider top than the bottom. Try to get a container as tall as it is wide and preferably even taller, otherwise the jello won’t fill the straws high enough. Extend each of the straws and pack the straws in as tightly as you can, adding more straws as needed to get a tight fit. Make sure that each straw is flush with the bottom of the container and that the bendable neck part (even though it is completely extended) is facing down. If your container is slightly wider on top than it is on the bottom, it may help, once the straws are packed tightly in, to rubberband the top of the straws to help when pouring in the jello.
  • In a medium, heat safe mixing bowl, preferably with a pourable edge, stir together plain and flavored gelatin powders. Pour the boiling water over the gelatin, stirring until it is fully dissolved. Allow the gelatin to cool for about 15 minutes, until it is slightly warm but not beginning to set. Stir in the whipping cream. Stir in the green food coloring until you get the desired color. You can see my worms were more gray than brown and I think I added about 10 drops of green food coloring so you may need to play around with the colors a bit, possibly adding a few drops of red or some other color.
  • Place your container of straws in a larger dish to catch any possible spills. With your container of straws prepped, gently pour the jello mixture over the straws. Don’t worry as you see the jello seeping up the sides of the container. If your straws are tightly packed in and flush with the bottom, they will still fill with jello.
  • Chill the jello straws for at least 8 hours. When the jello is set, remove the container from the refrigerator and run the sides under warm water until you can pull the straws and jello blob out of the container. This is the messy part – gently extract each straw from the mess and holding the top of the straw tightly with one thumb and forefinger, use the other thumb and forefinger to tightly apply pressure down the entire length of the straw thereby propelling the jiggly little worm from the straw.
  • Place the jello worms on a baking tray lined with wax paper and refrigerate until ready to serve. Serve in a chilled bowl.
