Why You’ll Love these Witch’s Brew Jello Cups
These spooky witch’s brew Jello cups offer three irresistible qualities that make them perfect for your Halloween gathering.
First, they’re ridiculously simple to make—just dissolve, pour, chill—even my most kitchen-challenged friends nail these every time.
Second, the customizable options let you match any party theme; swap lime for orange or grape, use sugar-free ingredients, or create that magical glow effect with LED lights underneath.
Finally, they’re a guaranteed kid-pleaser while still sophisticated enough for adults. The combination of wiggly jello, creepy gummy worms, and those staring candy eyes creates just the right balance of “eww” and “yum.”
What Ingredients are in Witch’s Brew Jello Cups?
These Witch’s Brew Jello Cups are the perfect spooky treat for your Halloween party with minimal effort. The bright green gelatin creates that quintessential “bubbling potion” look, while the creepy-crawly decorations take them to the next level of Halloween fun. What I love about this recipe is how the simple ingredients come together to create something that looks impressively eerie without requiring any actual witchcraft in the kitchen.
Ingredients:
- 2 (3 oz) boxes lime gelatin (Jello)
- 2 cups boiling water
- 1 cup cold water
- Whipped cream or whipped topping
- Gummy worms
- Candy eyeballs
- 8-10 small clear cups (4-6 oz each)
When shopping for these ingredients, keep a few things in mind. First, you can easily customize the color of your witch’s brew by swapping lime gelatin for orange, grape, or cherry to match your party theme. For guests with dietary restrictions, consider using sugar-free gelatin and unsweetened whipped cream to reduce the sugar content. And always check the packaging on gummy worms if you’re serving guests with allergies, as many contain gelatin and other potential allergens. The clear cups are essential for showing off your spooky creation—plastic works great for kids, but small glass tumblers can make them look more sophisticated for an adult gathering.
How to Make these Witch’s Brew Jello Cups

Making these spooky treats couldn’t be easier—perfect for those of us who want maximum Halloween impact with minimum kitchen stress.
Start by whisking 2 (3 oz) boxes of lime gelatin with 2 cups of boiling water in a large bowl until completely dissolved. This is where the magic begins, as the powder transforms into that vibrant green liquid that looks straight out of a cauldron. Once the gelatin has dissolved, stir in 1 cup of cold water to cool the mixture slightly. The temperature balance here is essential; too hot and your cups might warp, too cool and you’ll get clumps.
Next comes the portioning step, where you’ll divide the green gelatin mixture evenly among 8-10 small clear cups (4-6 oz each). The transparent containers are vital for showing off that eerie green glow.
Place the filled cups carefully in the refrigerator and let them chill until fully set, which takes about 2-3 hours. Can you believe the hardest part is simply waiting? I often prepare these the night before a party, giving them plenty of time to set up perfectly.
When you’re ready to serve, it’s decoration time—the most fun part! Top each cup with a generous dollop of whipped cream or whipped topping, creating a foggy, cloudy effect on your potion.
Then, partially insert gummy worms so they appear to be crawling out of the brew, and press candy eyeballs into the whipped cream for that final touch of Halloween creepiness. These can be made up to 2 days ahead and stored covered in the refrigerator, but I recommend adding the whipped cream and decorations just before serving to keep everything looking fresh and ghoulishly perfect.
Want an extra-spooky presentation? Try serving them on a black tray with green LED string lights underneath for a truly supernatural glow.
Witch’s Brew Jello Cups Substitutions and Variations
While these Witch’s Brew Jello Cups are already bewitching with their classic lime flavor, I’ve found that customizing the recipe adds another layer of fun to your Halloween festivities. Try swapping lime for orange gelatin to create a pumpkin-inspired potion, or go with grape for a deep purple cauldron effect. Cherry makes a blood-red brew that’s perfectly spooky.
For a magical glow, I place green LED lights under clear cups on a black tray. The effect is, quite literally, supernatural. Need a lower-sugar option? Sugar-free gelatin and unsweetened whipped cream work beautifully, without sacrificing any of the creepy charm.
What to Serve with Witch’s Brew Jello Cups
When planning your Halloween party menu, pairing these spooky Witch’s Brew Jello Cups with complementary treats creates a balanced spread that’ll impress your guests.
I like to serve mine alongside “mummy” hot dogs wrapped in strips of crescent dough, ghostly deviled eggs with olive eyes, and crispy bat-shaped tortilla chips with blood-red salsa.
For drinks, try bubbling punch with dry ice or “poison” apple cider.
Don’t forget finger foods—literally! Breadstick “bones” with marinara dip are always a hit with kids.
These combinations give everyone something substantial to balance the sweet, jiggly treats.
Final Thoughts
These Witch’s Brew Jello Cups have become a staple at my Halloween parties for good reason.
They’re incredibly simple to make, yet they never fail to impress kids and adults alike with their spooky charm.
I love how versatile they are—swap out the lime for orange or purple gelatin depending on your theme or mood.
What I appreciate most is how these can be prepped days ahead, saving me from last-minute party stress.
Just add the creepy toppings right before serving, and watch your guests’ faces light up.
Honestly, is there anything more satisfying than a dessert that’s both delicious and delightfully disturbing?
