The sugar-free chocolate shell on these keto mint chocolate ice cream bars cracks when you bite in — no-churn, cool, and creamy underneath, at just 1.4g net carbs. Once summer hits, I keep a batch in the freezer every week.
I started making these back in 2019 when I realized every frozen mint treat I tried tasted like toothpaste. The problem was always too much extract and not enough fat to carry the flavor. This version tastes like a York Peppermint Patty, and I'm not the only one who thinks so.
The base is dead simple: heavy cream, powdered erythritol, mint extract, and a pinch of salt. No churning, no custard, no egg tempering. You mix everything in a bowl, pour it into molds, and freeze overnight. That's it. The whole active prep takes maybe ten minutes, and most of that is measuring. I've been making double batches since my husband started sneaking them out of the freezer when he thinks I'm not looking.
What makes these bars work is the chocolate shell. I melt ChocZero sugar-free chocolate chips with a little coconut oil, drizzle it over the frozen bars, and it sets up into that clean snap you get from a real dessert bar. The coating hardens in about five minutes back in the freezer.
A few things I've learned after making these dozens of times. Powdered erythritol is non-negotiable for frozen desserts. Granulated recrystallizes as it freezes, leaving a gritty, sandy texture that ruins the whole bar. If you only have granulated, pulse it in a blender for 30 seconds until it's powder. I also learned (from reader Lindsey) that running the mold under warm water for three seconds before unmolding makes them slide right out. I'd been wrestling with mine for months before that tip.
These low carb mint chip bars are the ones I bring to summer cookouts. They don't melt as fast as traditional popsicles and people always assume they're from a store. My neighbor asked me to make a batch for her daughter's birthday party last July. That's when I knew the recipe was dialed in.
No-Churn Sugar-Free Mint Chip Bars
Mint chip has been my favorite flavor since I was a kid, and going keto didn’t change that. I just had to figure out how to make it myself. Three ingredients, no churning, and they freeze into bars with a texture that rivals anything from the store. The mint comes through clean (not like toothpaste, which is what most low carb versions get wrong), and the chocolate shell sets up with that satisfying crack.
If you’re building out a freezer stash like I do every May, pair these with my strawberry version and the bubblegum flavor for variety. Between the three, I’ve got something for everyone who shows up to a cookout.
Substitute with Real Mint
For a stronger mint hit, I swap the extract for fresh peppermint. I grow mine in a pot on the back porch, but grocery store mint works fine. Coarsely chop about a quarter cup of leaves, drop them into the heavy cream, and simmer on low for five to ten minutes. The cream turns this pale green that tells you the flavor has infused. Strain out the leaves, let it cool, and continue with the recipe. I prefer extract most of the time because it’s faster, but the fresh version has a softer, more herbal flavor that some people like better.
Make it Mint Chip
The chocolate shell is what makes these bars feel like something you’d buy, not something you made at home. I thinly slice sugar-free chocolate chips before folding them into the cream mixture so you get bits of chocolate in every bite rather than one big chunk. For the outer coating, I melt the chips with half a teaspoon of coconut oil. That small amount of oil is the difference between a shell that cracks cleanly and one that crumbles.
I use ChocZero chips for both the inside and the coating. Their chocolate tastes nearly identical to regular chips, and the texture holds up in the freezer without getting waxy. Every bite alternates between creamy mint and a slight crunch from the chips. That contrast is what keeps me reaching for another bar even after I’ve had two.
Popsicle Mold
The mold you use matters more than you’d think. I’ve tried cheap plastic ones, silicone trays, and even dixie cups with popsicle sticks jammed in. My favorite is this silicone oval mold because the bars come out shaped like Haagen-Dazs bars (thicker and more filling than standard popsicle shapes) and the silicone flexes so they release without breaking. I also keep these standard plastic molds around for fruit popsicles, but they work here too.
If you don’t own molds, pour the mixture onto a parchment-lined baking sheet and freeze flat. Once it’s solid, slice into bar shapes with a sharp knife. Run the mold (or the sheet pan) under warm water for about three seconds before unmolding and everything slides right out. That tip came from a reader and I use it every single time now.
Storage
I wrap finished bars individually in plastic wrap and stack them in a freezer bag. They keep for up to two months this way without picking up freezer flavors. If you skip the wrap, separate layers with parchment. Mine stick to each other within an hour if they’re touching, even in an airtight container. I usually make a batch of 8-10 on Sunday and they’re gone by Thursday, so long-term storage has never really been my problem. If you want variety in the rotation, I also keep chocolate mousse in the fridge for nights when I want something that doesn’t need thawing.
How to Make No-Churn Mint Chip Bars
Mix heavy cream, powdered sweetener, mint extract, and a pinch of salt in one bowl. Pour into molds, insert sticks, and freeze overnight. The next day, melt sugar-free chocolate with coconut oil, drizzle it over each bar, and freeze again for five minutes. I've made these with my ten-year-old and she handles the mixing herself. The only part that needs a second set of hands is the chocolate dip since you're juggling melted chocolate and frozen bars at the same time.

Frequently Asked Questions
Why use powdered erythritol instead of granulated in frozen desserts?
I learned this the hard way. My first batch had granulated erythritol and every bite was sandy and gritty. Powdered dissolves completely into the cream base, so the bars freeze smooth. If your store only carries granulated, I pulse it in my blender for about 30 seconds until it's a fine powder. That fix takes the grit out completely.
Peppermint extract vs mint extract: which gives a stronger flavor?
I use mint extract for a classic mint chip flavor (think York Peppermint Patty). Peppermint extract is sharper and more intense, so if that's what you have, start with 1 teaspoon instead of 1.5 and taste the base before pouring. One of my readers swapped to peppermint and said the flavor came through way stronger, which she loved. Mint extract is more forgiving if you're making these for the first time.
How do I unmold the bars without them breaking?
Run the mold under warm water for about three seconds, just long enough to loosen the edges. I do this every time now and they slide right out in one piece. Before I learned that trick, I was prying them out with a butter knife and losing chunks of the chocolate shell. If you're using the sheet pan method, a thin spatula works better than your hands.
Can I make these without molds using a sheet pan?
I've done this when all my molds were already full and it works great. Line a baking sheet with parchment, pour the mixture about half an inch thick, and freeze until solid. Then slice into bar shapes with a sharp knife and dip each one in the melted chocolate coating. The shapes aren't as uniform, but the taste is identical.
Is there a dairy-free option for these bars?
Full-fat coconut milk is my go-to swap for heavy cream in keto frozen treats. The texture is slightly icier than the cream version, but the coconut adds a subtle richness that pairs well with the mint. I've also tried unsweetened almond milk, but it freezes much harder and doesn't have the same body. Stick with full-fat coconut if you go dairy-free.
How long do these keep in the freezer?
I've kept them for up to two months with no change in flavor. The key is wrapping each bar individually in plastic wrap before putting them in a freezer bag. Without the wrap, they pick up whatever else is in your freezer. My freezer always has garlic bread in it, so I learned this lesson fast.
Can I turn this into scoopable mint chip instead of bars?
I've done this. Add a tablespoon of vodka to the base (it keeps it from freezing rock-hard), pour it into a loaf pan, and freeze for about four hours, stirring with a fork every hour. You can also churn it if you have a machine. I've used ChocZero vanilla syrup instead of vodka and that works too. The texture won't be identical to churned shop-bought, but it scoops well and the mint flavor is the same.
Can I add other flavors or mix-ins to these bars?
I've thrown in crushed pecans, sugar-free cookie pieces, and even a swirl of chocolate sauce before freezing. The base is forgiving, so most mix-ins work as long as they're small enough not to block the mold opening. My favorite variation is adding a tablespoon of cocoa powder to half the batch for a double-chocolate mint version. Just fold mix-ins in gently after the base is fully mixed.
Nobody warned me the sticks tip over in the mold, so now I freeze it about an hour first, then push them in. Straight every time! Annie, your freezer desserts have saved my summer. 😂
Chris, overnight is when they’re actually right. Four hours and they’re still a little soft in the center. I go in before dinner, pull them the next morning.
Ran out of green food coloring on batch three (pool day, didn’t want to run to the store). Left it out and the bars came out cream-colored and tasted exactly the same, honestly surprised me more than it should have. Four stars because I still can’t get the chocolate to set evenly on both ends.
Pool day logic is solid, and the green is purely cosmetic anyway. For the ends, do one at a time and give them 10 minutes in the freezer between dips. The chocolate won’t set on a warm bar.
Took me a few batches to nail the extract amount. Push past 2 teaspoons and it crosses into toothpaste, pull back to 1.5 and it actually tastes like mint chocolate.
Those Andes mint chocolate ice cream bars from the gas station freezer were basically my entire summer as a kid, so this hit somewhere unexpected. The chocolate shell actually cracks the same way. Used Lily’s chips and the snap was real.
Lily’s was my first test chip for the shell, and once I got that crack I never tried anything else. That Andes-in-a-gas-station-freezer snap was exactly what I was chasing.
I’ve tried every keto ice cream bar recipe out there and most of them skip the coconut oil in the shell, which is exactly why they don’t crack right. This one does.
Swapped the mint extract for peppermint extract (had it on hand) and the flavor came through way stronger, almost like a real mint chip bar from the ice cream shop. I also used Lily’s dark chocolate chips for the coating and it set up noticeably snappier than I expected, that clean crack when you bite through. One thing I figured out: run the mold under warm water for about 3 seconds before unmolding and they slide out perfectly instead of sticking. Batch two already in the freezer.
Lily’s sets up so much cleaner than most brands. And three seconds is exactly right on the unmolding (I ran mine under too long once and the edges started softening before they even hit the plate).
I have never made ice cream at home before and honestly the mint extract smell while I was mixing everything had me worried I’d just eat the batter. The chocolate shell cracked exactly like it should and I stood at the freezer eating one way too fast for a first timer.
That toothpaste thing is almost always peppermint extract. Mint extract has a softer ceiling. Gets you right to York territory without going medicinal.
Making a big batch this weekend to get ahead of summer. Once they’re frozen and dipped, do you separate them with parchment or is there another trick to keep them from sticking?
