Keto Sugar-Free Lychee “Eyeball” Jelly with Raspberry Cores

Halloween snacks have a way of stealing the show at any party. But the real winners are the recipes that balance spooky looks with great taste.

That’s where this Keto Sugar-Free Lychee “Eyeball” Jelly with Raspberry Cores steps in. It’s creepy enough to make the kids shriek, but tasty enough for adults to grab seconds.

Here’s the kicker, it’s low-carb, sugar-free, and keto-friendly. So you can snack away without feeling guilty about your blood sugar spiking or breaking your diet.

This recipe may look like a fancy Pinterest project, but it’s much easier than it seems. Think lychee fruit stuffed with berries, suspended in a light jelly, shaped into eerie “eyeballs.” The texture is juicy, soft, with just enough bite to feel like a fun dessert.

Let’s break it all down step by step, but before we cook, let’s talk about the ingredients and why they work so well.

Why Lychee Makes the Perfect “Eyeball”

Lychee fruit is naturally round and pale, almost white. When you peel it, it’s slightly translucent and glossy. Honestly, it already looks like something that belongs in a mad scientist’s jar. That’s half the job done before you even start.

Now, lychee has a subtle floral sweetness. It’s not overwhelming, and it blends nicely with tangy fruit like raspberries. On keto, you can use canned lychee packed in juice (not syrup) or fresh lychee if you can find them. Just rinse off any juice and keep the fruit cold until you’re ready.

When you push a red raspberry into the hollow center of a lychee, it looks exactly like a pupil. Suspended in clear jelly, the effect is… let’s just say, party guests might hesitate before biting into them. But after one taste, they won’t stop.

Sugar-Free Jelly Base

The other star of this recipe is the jelly base. We’re going sugar-free here, which means ditching the usual packets of gelatin loaded with sugar. Instead, we’ll use unflavored gelatin with a keto-friendly sweetener like erythritol, monk fruit, or allulose.

Why not just skip the sweetener? Because plain gelatin tastes bland, and the fruit flavors need a little lift. A small amount of sugar-free sweetener gives you that dessert-like finish without blowing up your carb count.

The jelly itself is like a stage for the eyeballs. You want it clear, firm enough to hold its shape, but not rubbery. Once set, you’ll cut into it and reveal dozens of floating “eyeballs.”

Flavoring Options

You can flavor the jelly in a bunch of ways, depending on what vibe you want:

• Classic clear look: Use plain water with sweetener and a splash of lemon juice. Keeps the jelly see-through, so the eyeballs are obvious.
• Haunted vibe: Add sugar-free grape or blueberry drink mix. The jelly turns purple or blue, giving the dessert a darker, creepier background.
• Bloody swamp look: Mix in a few drops of red food coloring, swirl it lightly so it’s streaky, not solid red. Looks messy in the best way.

Tools You’ll Need

• Mixing bowl
• Small saucepan
• Silicone mold or glass dish (you can use a round silicone mold for a sphere effect, or just pour everything into a dish and cut it later)
• Spoon
• Refrigerator space

Ingredients

• 1 can of lychees in juice (or about 20 fresh lychees, peeled and pitted)
• 20 raspberries (fresh or frozen, thawed)
• 2 cups water
• 2 tablespoons powdered erythritol or monk fruit (adjust to taste)
• 2 teaspoons unflavored gelatin (about 2 packets)
• 1 teaspoon lemon juice
• Optional: a few drops of food coloring or keto-friendly drink mix for effect

Step-by-Step Instruction keto Sugar-free lychee “eyeball” jelly with raspberry cores

Step 1: Prep the Lychees

Drain the lychees and pat them dry. If using fresh, peel and pit them carefully so you don’t tear the fruit. Each lychee has a hollow center—perfect for stuffing.

Gently push a raspberry into each lychee. The red “core” will peek out like an eyeball pupil. Place them on a plate and set aside.

Step 2: Make the Jelly Base

In a small bowl, sprinkle gelatin over half a cup of water. Let it bloom (sit and absorb) for about 5 minutes. It’ll look grainy and thick.

Meanwhile, heat the remaining 1.5 cups of water in a saucepan. Stir in the sweetener until dissolved. Add lemon juice.

Once hot but not boiling, remove from heat. Stir in the bloomed gelatin until smooth. If you want coloring or flavor mix, stir it in now.

Step 3: Assemble the Eyeballs

Pour a thin layer of jelly mixture into your mold or dish. Chill for 10 minutes until slightly thick but not fully set. This helps keep the eyeballs from sinking straight to the bottom.

Arrange the stuffed lychees over the layer, pupil side down. Carefully pour the rest of the jelly mixture on top, covering the fruit completely.

Step 4: Chill and Set

Refrigerate for 3–4 hours, or until the jelly is fully set.

Step 5: Serve and Shock

To serve, cut into squares or unmold if using silicone. Each piece will reveal floating eyeballs. For extra drama, drizzle sugar-free raspberry sauce around the plate for a “bloody” effect.

Tips for Success

• Don’t rush the bloom: Gelatin that doesn’t bloom properly will clump, and nobody wants lumps in their dessert.
• Cold raspberries work best: If the fruit is too soft, it’ll collapse when you stuff it inside the lychee.
• Clear molds make it spookier: If you use a glass dish, guests can see the eyeballs before you even cut into it.
• Batch size: One can of lychee usually gives around 20 fruits, which works great for a medium tray. Double it for a party crowd.

Keto-Friendly Sweetener Choices

People on keto often argue about which sweetener is best. Here’s the breakdown:

• Erythritol: Neutral flavor, doesn’t spike blood sugar, but can leave a cool aftertaste.
• Monk Fruit: Smooth sweetness, works well in small amounts.
• Allulose: My personal favorite—melts perfectly and gives a sugar-like finish.

Stick to powdered versions, since granulated sweetener can make the jelly gritty.

How It Tastes

Imagine biting into a soft lychee that’s juicy and slightly floral, with a surprise burst of tart raspberry in the middle. The jelly around it is cool, lightly sweet, almost refreshing. It’s a balance of textures—chewy, juicy, wobbly. Not too heavy, which makes it perfect for a Halloween spread where you’ve already got candy and heavier desserts everywhere.

And because it’s sugar-free, you don’t feel sluggish after eating a few. Keto folks appreciate the carb count, and kids honestly can’t tell the difference.

Serving Ideas

• Halloween Party Platter: Arrange them in a glass bowl with red sauce drizzled through, like a bowl of eyeballs.
• Individual Cups: Make mini servings in small jars so everyone gets their own set of eyeballs floating in jelly.
• Extra Gore: Drop a little raspberry puree inside some lychees before sealing with whole raspberries. Looks like bloodshot pupils when you bite in.

Storage and Make-Ahead

You can make this dessert 1–2 days ahead. Just keep it covered in the fridge. The lychees stay juicy, the jelly holds firm, and the raspberries don’t bleed too much color.

If you store longer than 3 days, the fruit may start breaking down, and the effect won’t be as sharp. So plan to prep close to your event for best results.

Why I Love This Recipe

A few years back, I was the person who always volunteered to bring the “fun” Halloween dish. I used to make bowls of candy corn cupcakes or spider web brownies. But once I switched to keto, I didn’t want to show up empty-handed—or worse, with a “boring” salad while everyone else was munching cookies.

So I experimented with lychee eyeballs. The first time, I didn’t even use jelly, just lychee stuffed with blueberries. The kids screamed (in the good way) and the adults actually ate them. That’s when I realized—this dish checks every box. Creepy, fun, tasty, and not a sugar bomb.

Over time, I added the raspberry cores for a scarier effect, and then suspended everything in jelly. It turned into a Pinterest-level party piece, but honestly it’s so simple I whip it up every October.

How to Get That Pinterest Look

If you want photos that make people stop scrolling:

• Use a glass bowl so the “eyeballs” show through the jelly.
• Place the lychees pupil side down so the raspberries stare out.
• Add a drizzle of sugar-free raspberry syrup on top before serving.
• Scatter a few plastic spiders or fake cobwebs around the dish for the table setup.

Even if you’re not into photography, the dish is naturally striking. People will pull out their phones before eating.

Variations

• Blueberry pupils: Use blueberries instead of raspberries for a darker, less bloody look.
• Gummy core: Drop a sugar-free gummy bear inside the lychee instead of fruit for a chewy surprise.
• Coconut jelly base: Mix coconut milk with the gelatin for a milky look. Makes the eyeballs look like they’re floating in fog.

Why This Recipe Works for Keto

Halloween is one of the hardest times to stay on keto. Candy is everywhere, sugar sneaks into every dish, and the dessert table feels like a trap. This recipe gives you an option that’s festive and fun without making you feel left out.

It’s low-carb because the main ingredients, lychee, raspberries, and sugar-free gelatin, fit perfectly within keto macros. It’s also portion-controlled, since each eyeball is bite-sized. And because the sweetness is balanced, you don’t get that artificial taste that sometimes ruins keto desserts.

Conclusion

Keto Sugar-Free Lychee Eyeball Jelly with Raspberry Cores is one of those rare recipes that’s creepy, tasty, and diet-friendly all at once. It’s the kind of Halloween dish that makes people point, laugh, hesitate, and then eat every last piece.
