It’s always cool to have a really gross dish of treats out for Halloween and these Bloody Worms of DOOM are definitely a winning recipe. I don’t have any kids, but I bet kids would love not only making these but having them out for a Halloween party treat.
The worms are pretty straightforward to make. Basically they are a really sturdy gelatin mold that you mix with cream to produce a kind of milky texture. The cream also gives the worms some great color. Why are these worms of doom? Well, just look at them?! Don’t they fill you with a sense of dread?

Creepy!
There are just a few simple ingredients for these guys. You can make 100 worms for under $10 depending on Oreo costs in your neck of the woods. They were definitely the most expensive part for me.
Bloody Worms of Doom (Adapted from an Idea Room recipe. The Oreo dirt was my addition.)
- 100 flexible party straws
- 1 6 ounce box of red Jell-o flavoring of your choice (raspberry, cherry, or strawberry are your options I think)
- 4 packages gelatin.
- 4 Cups boiling water
- 1 Cup heavy cream
- 15 drops green food coloring
- 20 Oreo cookies (You could set the out without the dirt, but the dirt is pretty tasty honestly.)
- Wax paper
- An empty paper milk carton or a tall jar or plastic container to keep the worms in while they harden.
Making the mixture. If you’ve ever made Jell-o then you can probably handle this. First, get your Jell-o ready along with your 4 packages of gelatin.

Worms deconstructed.
Pour these ingredients all into a large boil and mix them up well. Make sure you don’t have areas of just gelatin or it might not distribute well and you’ll have jelly clumps in your worms!
This is how it should NOT look.

Mix this up well. Clumps of gelatin are very bad.
For regular Jell-o you mix some hot and some cold water but for this we want to use all hot water or we’ll run the risk of not dissolving everything well. That’s a LOT of gelatin in the bowl and want to make sure it gets all dissolved.
For regular gelatin users, there’s no need to “bloom” the gelatin for this recipe. By mixing it together with the Jell-o packet it distributes the gelatin crystals enough to avoid clumping.
Anyway, then add 4 cups of boiling water and stir it up well until everything is dissolved!

Kind of slimey.
Cool the mixture. We need to add some cream to this, but don’t do it now! I made this mistake the first time I did it because I wasn’t thinking and my cream immediately curdled and I had to start all over. To do it correctly, set your bowl in the fridge for about 20 minutes until the liquid is room temperature. SET A TIMER because if you forget about it, it will turn into a very large red block which will be very hard to re-liquefy.
Worm molds. While your mixture is cooling, you can get your straws ready. The ones with the bendy necks work best because they give the end of the worm some texture. Make sure you extend the straws to the maximum length by pulling on the ends. Stretch them all out and then secure them with a rubber band so you have one big bundle.

Worm bodies.
You might think that 100 straws is a lot, but it really doesn’t take that long to handle them. Once your bundle is together, stick it in your carton or container. I decided to use a very large, tall jar I use to store pasta normally.
In hindsight, I would’ve used a milk carton (washed obviously) because these straws were a pain in the neck to remove once they were solidified and with the milk carton you can just cut it apart.
One note on straws: If you use the bendy neck straws, make sure to put the bendy necks at the bottom of your container! If they are at the top, your mixture might not fill up high enough to get to the bendy part and you’ll have non-textured worms. If I went to a Halloween party and they had non-textured worms, I would probably leave. Just saying.

In retrospect, a carton might be easier.
Finishing the mixture. Once your mixture is room temperature, add your cup of cream. Mix it up well.

Cool.
Also add your green food coloring now which gives the worms a bit more bloody and doom-like coloring.

Color drops!
Note on the cream: It’s pretty hard to get your cream completely combined. It’s okay if there are some dots of cream in there. It also might separate a bit in the final product, but it should still harden without a problem.
Whisk the food coloring and everything together and then pour it over your straws and fill up your container. It probably won’t go all the way up the straws. Let this chill in your fridge overnight or for at least 8 hours.
Making the worms! Ok. Now for the fun part. Cut apart your carton and get your straws separated from the mold. Then lay out 12 inches or so of wax paper and starting from the non-bendy end of the straw, squeeze out the worm using your fingers! If the straw or your hands get slippery, have some paper towels on hand to dry out.
This is one lonely worm:

Works like a charm! Wax paper is key.
I will say that it does take about 20 minutes to actually get all the worms out of the straws. For me, it was fun for about the first 30 worms. Then it got old. If I would’ve had like two helpers it would’ve been perfect.
Once you squeeze the worms out on the wax paper and have an even row of worms, put another layer of wax paper right on top of the worms and keep squeezing! I did 3 layers of 33 worms each. Then add one more layer of wax paper over the very top layer and you can roll up the worms in a nice little package!

100 worms.
You can keep this in the fridge for a few days without a problem until you need them.
Want to see what I was talking about how I chose the wrong vessel for keeping the straws in place? I had to pry each straw out of this disaster:

Art!
A carton would’ve been much easier.
Making the dirt. Take 20 or so Oreos and remove the fillings with a spoon. Then give the cookies a spin in a food processor or you can just crush them up by hand. Toss the worms in the dirt and pile everything up in a big bowl!

Tastes great with the dirt mixed in.
This was kind of a long post, but now you know how to make worms!
These weren’t really that much work although if you’re like me, they will leave your kitchen and fingers covered with a faint red coating. But seriously, the final product is pretty cool I think.


















Awesome! I love the final touch of the straws bands making the ridges in the worms. This recipe would be awesome for those gross-out Halloween parties.
Dude, just buy gummy worms next time!!!
I have made pots of dirt(choc.pudding) with earth(crushed oreo, leave middles in, you can’t tell)and gummy worms for 20 years.
I really appreciate your efforts but if life gives you a break take it. Buy your worms ready made and sigh with relief.
???What pray tell did you do with all the jello in the jar???
@kat Haha. Yea… It’s kind of more of a crafts project than a fastest way to get gummy worms thing. ;)
Got any ideas for leftover jell-o?
Man-o-man. You have much, much more patience that I do. Just reading this post made me tired.
We saw these yesterday on another website and are going to make them this weekend for our Halloween party! I love the dirty addition though. Thanks for the post!
how creative! but I almost threw up looking at these :) guess, you’ve achieved what you set out for.
this is intense, even for a crazy person like me who makes her own gnocchi and marshmallows… :)
AWESOME! Those are so freaking cool. I love it!
OMG. They look so real!
that first pic is disgusting! but I love it.
they really do look so real. submit these bad boys to tastespotting.
Haha. Thanks everyone. Yea. You definitely can get the color just right if you make them yourself. I’ve never seen storebought worms with the deep red color like that. :)
EEEW! That is so gross! ; p
This is probably the coolest jello thing or anything I’ve seen someone make!
That is amazing! They look so real and freaky (and disgusting!)

I wonder if it would be faster to squeeze the worms out of the straws with, say…a rolling pin? Maybe you could do 5 or so at a time that way? Just a thought. :-)
We just made a batch and have them chilling in the fridge! I hope they turn out. Thanks again for the post
Awesome, I love you effort! Always better from scratch, although I don’t know that I would be trying this one out. Just thought I’d mention, that you can buy oreos already crushed up sans filling. Just an FYI, it’s cheaper than the whole cookies.
Nick,
We have a Halloween party every year, and, as the mama of two little boys, I can guarantee you that these will most certainly be added to the list of things to make!!
