I don’t know a single person who doesn’t love ice cream. I also don’t know a single person who doesn’t love easy and convenient recipes. We’ve combined both to make this Keto Mason Jar Ice Cream! We recreated my favorite ice cream flavor, butter pecan, into an easy to make, no equipment needed recipe. Could it get any better?!

Carbs in Heavy Whipping Cream
People often get confused about how many carbs are really in heavy whipping cream. Some labels will round down and list 0g of carbs, others will say 1. The truth is that there are about 9 grams of carbs per cup of heavy cream, or about 1/2 a gram of carbs per tablespoon. Regardless of what the nutrition label says on the one you are using, you now know how many carbs are actually in heavy cream.
We love using heavy cream in our recipes because it has a high fat to protein ratio while still keeping the overall recipe low in carbs. If you’re looking for more low carb recipes that are made with heavy cream check out some of our favorites:

Can I Freeze Ice Cream in Mason Jars?
Yes! This keto ice cream recipe can be frozen in mason jars without any issues. Whenever freezing anything (not just low carb recipes) in mason jars, make sure to leave a little room on top. Liquids like heavy cream expand when frozen so you’ll want to account for a little extra room. If you struggle with portion control try making single serve mason jar ice cream pots to avoid overeating. Plus these work great for storing other keto treats and snacks on the go.

Changing Up The Flavors
We based this keto mason jar ice cream off my favorite flavor butter pecan. If butter pecan ice cream doesn’t sound appealing right now, no need to worry! There are tons of different ways you can customize the ice cream to fit flavors you enjoy. If you’re into making meal plans, make the base for this keto mason jar ice cream and add different toppings so you’ll have the perfect macros for you every time.
What to Know Before Changing the Recipe
- This mason jar ice cream recipe has times based off of the butter pecan version. However, If you change the ingredients the chill time may be a little shorter, or a little longer to cool.
- The base of this mason jar ice cream should not change, but there are three ingredients you will need to leave out when changing the overall flavor. The 1/4c butter, imitation butter flavor, and pecans should be removed from this recipe before adapting it.
- The macros WILL change. If you change the recipe the macros will change because you have to remove fat from butter and pecans which have a large bulk of the calories. Know that if you add or take anything away the macros will need to be recalculated for your specific case to be accurate.
The Best Keto Mason Jar Ice Cream Add-ons and Flavors
Obviously the best flavor will be the one you love most, but we thought it’s best to give you some ideas! These are some of the most popular flavors, as well as our favorites, AND some that allow you to get extra creative in the kitchen.
- Brownie Batter Blast- Take this ice cream base and add in 2 tbsp of unsweetened cocoa powder to the recipe before shaking. While the ice cream is freezing, bake and cool our extra fudgy keto brownies. Chop the brownies into pieces after cooling and mix into, or place on top of your keto ice cream. Voila you have mason jar chocolate ice cream with tons of brownie bits!
- Peanut Butter Chocolate Ice Cream- Mix 2 tbsp of unsweetened cocoa powder into the ice cream base before shaking. Once the mixture has thickened drizzle in peanut butter or mixed up PB2 powder. You can lightly shake again, or just swirl it in with a spoon to get nice peanut butter ribbons. To make it extra tasty, you can even drop on a few keto chocolate chips like these
chocolate chips from Lily’s. - Strawberry Cheesecake Keto Ice Cream- Bake a half recipe of our keto strawberry shortcake pie crust (you can just lay it flat on a cookie sheet to bake). Once baked, set aside and allow to fully cool. Add 3 tbsp of softened cream cheese and 1/4 c of chopped strawberries (preferably frozen) into the ice cream before shaking. Now shake up everything well to combine and double the cream in size. Freeze the strawberry ice cream and then serve with crumbled up crust pieces.
How to Make Keto Mason Jar Ice Cream
A decadent treat low in net carbs, high in fat, and perfect for keto. Plus this low carb/ keto recipe is the perfect vanilla ice cream base to spice up however you want. Love plain vanilla ice cream? You’ve got it. Want to make keto brownie batter ice cream? All yours! This recipe is a great base open to whatever upgrades you desire.
Ingredients
To make an easy keto butter pecan ice cream you only need 6 main ingredients. We start with a base of 2 cups heavy cream. This will give the ice cream body and make it a super high fat dessert. You can’t make a mason jar ice cream keto without a high fat base. For sweetness we use erythritol and stevia for a nice blend. Next this wouldn’t be butter pecan without the butter and pecans! We recommend raw chopped pecans (that we will toast later) for the best overall flavor. Finally this recipe calls for vanilla extract and imitation butter flavoring. The butter flavor is optional, but to make this butter pecan ice cream we recommend it. Vanilla extract on the other hand is non negotiable in our opinion. Vanilla extract really brings out all the flavors in this keto mason jar ice cream for a well rounded dessert.
You “Cone” do it! Making Easy Keto Ice Cream
Don’t worry this keto mason jar ice cream is super easy to make and the prep time will be done before you know it. Begin by melting the butter in a small skillet. Next you will want to toast your chopped pecans in a pan or in the oven for 5-6 minutes. Make sure both the butter and pecans have cooled before adding them into the next mixture.
Combine all keto ice cream ingredients into your mason jar. With the cream in a mason jar shake vigorously for 3-5 minutes (make sure the lid is on all the way!). Once the cream has doubled in size, freeze for 3 hours, or up to 24 hours. Now serve!
Note: We find ice cream maker free ice cream to be best at 3 hours. It is at its creamiest point but not rock hard. If you want to freeze your keto mason jar ice cream for significantly longer or overnight, be sure to let it sit out for 5-7 minutes before serving.
Storage
The next time you make this recipe, and we know there will be a next time. Make a double batch in two mason jars! With only 3.5 hours total time, it will definitely be in your favor to make extra. Simply freeze any leftovers in the mason jar and pull it out 10-15 minutes before you plan on having some.

Keto Ice Cream Rocks! (No Literally)
For those that wonder “why is keto ice cream so hard?” we’ve got answers. Low carb/ keto ice creams use erythritol and other artificial sweeteners. Normally artificial sweeteners freeze VERY hard. So if you’re expecting super creamy soft serve, keto ice cream just isn’t that.
Softening Keto Ice Cream
There are a few ways you can go about softening keto ice cream. Trust us when we say though, some methods are much better than others.
- The famous “patience is a virtue”. This is the best way to soften keto ice cream by far. Simply pulling it out and waiting 10-15 minutes is the best way to give it that creamy factor without risking the formation of ice crystals later.
- The hot spoon trick. Place a metal spoon into sup hot/ boiling water and wait 2-3 minutes. Once the spoon is very hot scoop some of the ice cream out. You may need to repeat the spoon heating method.
- The microwave. This is by far my least favorite method because if you are reheating the whole container you will, without a doubt, create ice crystals on the remaining ice cream. NOTE: DO NOT HEAT IN THE MASON JAR. While some mason jars are temperature resistant you do not want to risk it. Going from super cold to hot is dangerous with glass. You should only use this method if you created the ice cream and then scooped it into a cardboard pint container before it had fully frozen.
Our Favorite Keto Friendly Ice Cream Brands
A lot of the time we are simply looking for a quick and convenient dessert to grab and take to the couch! We get it. We are the same way. However, sometimes the price of low carb ice creams in store can be very off putting. Plus when you actually look into them, the macros aren’t exactly what you’re looking for (aka a high carb count).
Our keto mason jar ice cream is a fraction of the cost when compared to store bought varieties. Plus the flavor can be tailored to your preference. If you are feeling like “big ball’in” as the kids say, some of our favorite low carb ice cream brands are So Delicious (butter pecan or mint chip), Enlightened ice cream popsicles, and Halo Top (mainly the original flavors – vanilla, strawberry and chocolate)! Give those a try and let us know how they compare to our homemade version.

You guys are the best.
I’ve made this before but I saw it again on Facebook the other day and made it this morning for tonight. Thanks. But where did you get those cute ceramic icecream cones???
Making this today..can’t wait !
I definitely love this ice cream but I kicked it up a bit, after toasting the butter pecans I made some caramel sauce an candied the butter pecans! OMGOODNESS little goes a long way soooo good. Better than any store bought. My sweetener was a little over a 1/3 cup of confectioners swerve!!!
I am not fond of nuts in my ice cream. I would prefer vanilla. How do I make that substitution? And you use protein powder to make a different flavor. How much? What kind? Really need more information on changing the flavors.
Did you get an answer? I don’t see any replies to any of the questions??
No, I did not get answer. They don’t seem to be efficient about answering the questions. I thought the recipe sounded easy, but I would prefer a different flavor. And I can imagine getting the ice cream out of a mason jar would be difficult. So what else would you use to make it? Need some help here.
Needed more nuts ir something. And the nuts sank to the bottom.
Anything I can do to keep the pecans from settling in the bottom of the jar? Its still good btw; thanks!
Yummy I’m going to do with on my days off
I loved this so much but I used mint chocolate chip. Green dye, unsweetened chocolate chips mint extract and sweetener. Thank you! I missed ice cream!
How would you measure the 1 serving. I’m confused.
Hi, I was wondering why you guys use both erythritol and stevia? But in other recipes you only use erythritol??? Thanks
Can I use powdered monk fruit sweetener instead of liquid Stevia? My monk fruit contains erythritol also so should I remove that from the recipe?
Can this be blended instead of shaken?
You have to be “young” to make this???
I am a dairy free keto. Have you tried to do this technique with coconut cream instead of HWC?
Thanks,
Lynn
I can’t shake vigorously, and do not own a blender. Do you have any idea whether I could ‘whip’ (shake) this in the food processor and then transfer to the freezer? I’m drooling to make this!
I have seen in alot of recipes that call for 2 types of sweetener. Like the above Butter Pecan Ice Cream, powdered erythritol and liquid stevia. Why not one or the other. Just curious. I love all ya’lls videos and recipes!!!
Is it supposed to have like a butter-like consistency? Because in room temperature, it stays solid and doesn’t seem to melt?
If I make half of the amount of this recipe, do I still have to wait 3 hours??
You can certainly peek in on it sooner and see if it’s at the desired consistency!
I made it with buttered almonds, had no pecans. Tasted great but the almonds huddled in the bottom of the jar. Butter adds great flavor! Also I forgot and let it go longer than 3 hrs, and it took way longer than 5 minutes to thaw enough to allow more than scraping the top of the ice cream—my freezer is likely set colder than yours. Making my second batch today, no nuts, this is actually is kinda fun!
