Keto Lemon Popsicles – Bright, Refreshing, and Low-Carb
These Keto Lemon Popsicles bring a burst of sunny flavor without the sugar crash. They’re tart, lightly sweet, and perfectly icy for hot afternoons or post-dinner cravings. If you love the clean taste of lemon bars but want something lighter, these pops hit the spot.
The best part: you can make them with just a few ingredients and a blender. Keep a batch in your freezer, and you’ll always have a bright, keto-friendly treat ready to go.
Ingredients
Method
- Prep the lemons: Zest 1–2 lemons to get 1 tablespoon of zest. Juice enough lemons to yield 1/2 cup of fresh lemon juice. Strain the juice to remove pulp and seeds.
- Blend the base: In a blender, combine almond milk, heavy cream (or coconut cream), lemon juice, zest, sweetener, vanilla, and salt. If using xanthan gum, sprinkle it in while blending to avoid clumps.
- Taste and adjust: Lemon intensity and sweetness are personal. Add a bit more sweetener if it’s too tart, or an extra tablespoon of lemon juice if you want more zing.
- Strain for smoothness: For an extra-smooth pop, pour the mixture through a fine-mesh strainer into a pitcher. This step helps remove any undissolved sweetener or zest clumps.
- Fill the molds: Pour the mixture into popsicle molds, leaving a little room at the top for expansion. Insert sticks.
- Freeze: Freeze for 4–6 hours, or until fully solid. Overnight is best for clean unmolding.
- Unmold: Run warm water over the outside of the molds for 10–15 seconds. Wiggle sticks gently until the pops slide out.
- Optional finish: For a “lemon bar” vibe, dust with a tiny pinch of powdered keto sweetener before serving.

What Makes This Special
These popsicles lean into the pure, bright zing of real lemons. No artificial flavors or complicated steps.
They’re sweetened with a keto-friendly sweetener and balanced with a touch of fat for better texture and a more satisfying bite. The result is a creamy-yet-icy pop that feels like a sorbet, with fewer carbs and no added sugar. They also come together fast, which makes them ideal for busy weeks.
What You’ll Need
- Fresh lemons: About 4–5 medium lemons for juice and zest (you’ll need 1/2 cup lemon juice and 1 tablespoon zest).
- Unsweetened almond milk: 1 cup, for a lighter base.
You can swap with coconut milk for a creamier texture.
- Heavy cream or full-fat coconut cream: 1/2 cup, to add body and smoothness.
- Powdered erythritol, allulose, or monk fruit blend: 1/3–1/2 cup, to taste. Powdered forms dissolve better.
- Vanilla extract: 1 teaspoon, for roundness and depth.
- Pinch of sea salt: Enhances the lemon flavor.
- Optional: 1/8 teaspoon xanthan gum for extra creaminess and fewer icy crystals.
- Equipment: Popsicle molds, sticks, a blender or whisk, and a fine-mesh strainer.

Keeping It Fresh
Popsicles can pick up freezer odors if left uncovered. Once frozen, remove them from the molds and wrap each pop in parchment or plastic wrap, then store in a freezer-safe bag. Squeeze out excess air for best results.
Properly wrapped, they stay fresh for up to 4 weeks. If you notice frosty buildup, it’s usually cosmetic and won’t affect flavor much, but you can let the pop sit at room temp for a minute to soften the ice crystals.
Health Benefits
– Low-carb and keto-friendly: Using erythritol, allulose, or monk fruit keeps net carbs low while satisfying a sweet tooth. – Vitamin C from fresh lemon: Lemon juice brings a small but meaningful boost of vitamin C, which supports immune health and collagen production. – Balanced sweetness: These pops rely on bright acid and a little fat, so you need less sweetener overall. – Light and hydrating: The high water content makes these pops refreshing after workouts or on hot days, without added sugar or dyes.
Pitfalls to Watch Out For
– Too icy: Water-only lemon pops can freeze hard. A bit of cream or coconut cream helps keep the texture smoother.
Xanthan gum can also reduce ice crystals. – Gritty sweetener: Granular sweeteners don’t dissolve well. Use powdered forms, blend thoroughly, and strain if needed. – Overly tart: Lemons vary. Start with 1/3 cup sweetener and adjust to taste.
Remember flavors dull slightly when frozen, so err on the slightly sweeter side pre-freeze. – Bitter zest: Avoid the white pith when zesting. Use light pressure and a microplane to get only the fragrant yellow part. – Loose sticks: If your mold doesn’t hold sticks steady, freeze the mixture for 45–60 minutes until slushy, then insert sticks and finish freezing.
Variations You Can Try
– Classic Lemonade: Skip the cream and use all almond milk for a lighter, more icy pop—like frozen lemonade on a stick. – Lemon Coconut: Use full-fat coconut milk as the base for a creamy, tropical twist. Add a teaspoon of shredded unsweetened coconut for texture. – Lemon-Berry Swirl: Blend a handful of raspberries or strawberries with a little sweetener.
Layer lemon mixture and berry puree in molds for a pretty swirl. – Lemon Basil: Steep a few basil leaves in warm almond milk for 10 minutes, cool, then blend. The herbal note pairs beautifully with lemon. – Lemon Ginger: Add 1–2 teaspoons fresh grated ginger (strained) for a zesty kick that’s great for digestion. – Lemon Cheesecake: Blend in 2–3 ounces of softened cream cheese. It adds tang and an ultra-creamy texture reminiscent of cheesecake.
FAQ
How many net carbs are in each popsicle?
It depends on your mold size and sweetener, but most standard pops come in around 1–2 net carbs when using unsweetened almond milk, heavy cream or coconut cream, and a zero-calorie sweetener.
Check your specific brands to be sure.
Can I use bottled lemon juice?
Fresh is best for flavor and brightness. Bottled lemon juice can work in a pinch, but it may taste flat or slightly bitter. If using bottled, add extra zest and a splash more vanilla to round it out.
Which sweetener works best?
Allulose and powdered erythritol or monk fruit blends are great.
Allulose tends to keep pops a bit softer and less icy. Avoid liquid stevia as the sole sweetener—it can taste bitter in citrus-heavy recipes.
How do I make them dairy-free?
Use full-fat coconut milk or coconut cream instead of heavy cream and stick with unsweetened almond or coconut milk for the rest. The result is creamy, rich, and fully dairy-free.
Do I need xanthan gum?
No, it’s optional.
It helps create a smoother texture and fewer ice crystals, but the pops will still be tasty without it. If you use it, a tiny amount goes a long way—don’t exceed 1/8 teaspoon.
Can I make this without a blender?
Yes. Whisk everything very well, use powdered sweetener, and strain the mixture before pouring into molds.
A blender simply makes it faster and helps with dissolving and aeration.
How long do they take to freeze?
Most molds take 4–6 hours to freeze solid. Overnight is safest if you want perfectly clean edges when unmolding.
My pops are stuck. What should I do?
Run warm water over the outside of the molds for 10–15 seconds and gently wiggle the sticks.
Avoid twisting too hard to prevent breaking the stick or cracking the pop.
Final Thoughts
Keto Lemon Popsicles are simple, bright, and endlessly adaptable. With a short ingredient list and minimal effort, you get a refreshing treat that satisfies dessert cravings while staying low-carb. Keep a batch on hand for hot days, after-dinner sweets, or whenever you want a clean, citrusy lift.
Once you master the base, try a few variations and make this your go-to freezer staple.
