My Spa Day in a Stick: Low Sugar Cucumber Lime Zing Popsicles
I used to buy those "light" fruit ice lollies from the supermarket — the ones marketed as the sensible choice, approximately 40% smaller than regular ones and still carrying 15 grams of sugar. I ate them feeling virtuous. I now know better.
These cucumber lime popsicles have 2 grams of naturally occurring sugar per pop. The sweetness comes from monk fruit, the freshness comes from actual cucumber, and the zing comes from real lime. They take ten minutes to make — not counting the freezing, which happens while you get on with your life.
One important note: flavours intensify before they go in the mould, then mellow significantly once frozen. Taste the mixture and make it slightly more lime-forward and sweeter than feels right — it'll land perfectly once frozen solid.

Ingredients
Makes 6 popsicles · Scale as needed
- 300g (2 cups) cucumber, peeled and roughly chopped
- 60ml (¼ cup) fresh lime juice (about 2 limes)
- 60ml (¼ cup) water
- 1–2 tbsp ⇄ monk fruit sweetener — the sugar syrup swap
- a few fresh mint leaves (optional)
Instructions
- 1
Add the chopped cucumber, lime juice, water, monk fruit sweetener, and mint leaves (if using) to a blender.
- 2
Blend until completely smooth. For a pulp-free popsicle, strain through a fine-mesh sieve — though I usually don't bother.
⇄ Swap NoteMonk fruit replaces sugar syrup here entirely. It provides the sweetness without the 13g of added sugar a typical fruit lolly carries. See the guide to using monk fruit instead of sugar for more on how it works in frozen applications.
- 3
Taste and adjust — add more lime or monk fruit if needed. Remember: flavours mellow when frozen, so go slightly bolder than you think.
- 4
Pour into popsicle moulds, insert sticks, and freeze for at least 4–6 hours until completely solid.
- 5
To unmould, run the outside of the mould under warm water for a few seconds and they'll slide out cleanly.
Cucumber, lime, water, monk fruit, optional mint — blended, poured, frozen. Ten minutes of actual effort.
Why Cucumber Instead of Fruit Juice?
Most commercial popsicles and homemade recipes use fruit juice or sugar syrup as the base — both deliver flavour and sweetness but also 12–18g of added sugar per lolly. Cucumber is mostly water (96%), which makes it a naturally low-sugar base that blends smoothly and freezes beautifully. The lime provides all the flavour intensity. The monk fruit provides the sweetness without glycemic impact. The result is something that actually feels more refreshing than a sugar-heavy lolly — lighter, cleaner, crisper. For the full sweetener comparison, the Swap Guide breaks it down.
Common Mistakes
- Not adjusting for freezing. Taste the liquid and it should feel slightly too sweet and too limey — that's correct. Frozen, it'll be perfect.
- Using bottled lime juice. Fresh lime juice is brighter and more aromatic. In a recipe this simple, it matters.
- Under-freezing. They need a full 4–6 hours minimum. If they're not completely solid they won't unmould cleanly.
Storage
Keep in the freezer in their moulds or individually wrapped for up to 2 weeks. Once unmoulded, eat within a few minutes — they melt quickly given the high water content.

Frequently Asked Questions
Do I need to peel the cucumber?
Yes, for the best texture and colour — cucumber skin can make the mixture slightly bitter and turns the popsicles a less appealing shade of green. Peel it first.
Can I use stevia instead of monk fruit?
Yes — granulated stevia works well here. Start with 1 tablespoon and taste, as stevia is slightly more intense than monk fruit. Liquid stevia (3–4 drops) also works.
Can I make these without popsicle moulds?
Yes — pour into small paper cups, freeze for 2 hours until partially set, insert a wooden stick, then freeze completely. Run warm water over the paper cup to unmould.
