Introduction to Keto Mason Jar Ice Cream
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:
Delicious Heavy Cream Desserts
- Low Carb Chocolate Gelato– An Italian delicacy turned keto with cream and sugar free cocoa powder. Gelato is fattier and richer than regular ice cream making it the perfect keto treat. For more sugar free ice cream recipes made with heavy whipping cream, check out our desserts section.
- Easy No Bake Cheesecakes– A smooth heavy cream and cream cheese base whipped together on top of a cashew crust. We even serve it with extra chocolate drizzled on top!
- Almond Milk Ice Cream – Perfect if you’re looking for a dairy free take on ice cream.
- Keto Frosty – this 3 ingredient (only!) keto frosty recipe does not use any artificial ingredients and is low in net carbs, which makes it a perfect keto dessert.
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 until lightly browned, 5-6 minutes, then remove from heat and cool completely.
Instructions
- In a small skillet, melt butter. Toast pecans until lightly browned, 5-6 minutes, then remove from heat and cool completely.
- Combine all ingredients in a wide mouth 24 ounce-sized mason jar. Secure the lid and shake vigorously for 3-5 minutes. The liquid inside should double in volume, filling the mason jar.
- Freeze for 3 hours up to 24 hours.
- Note: at the three hour mark we found the ice cream to be perfect consistency. If you are freezing for significantly longer/over night be sure to let it sit out for 5-7 minutes prior to enjoying.
