Why this Recipe Works
- It's easy. Just add everything to a mason jar and shake. This recipe is perfect for at home summer activities with the kids.
- It's perfect for single servings. No need to whip up a large batch of ice cream when you can just make a single treat and call it a day. Perfect for those of us that don't eat ice cream too often.
- The kids can do the hard parts! What I love most is that I can grab a few mason jars toast a handful of marshmallows in the oven and then get my kids to do the shaking. They love helping out with these ice creams and helping me to come up with new flavors.
🥘 Ingredients
Heavy Cream- This is the base of our ice cream and will make it nice and creamy. If you have to choose between different heavy whipping cream options, always go for the higher fat percentage because it yields a much creamier result.
Sugar- We only need a little granulated sugar to help sweeten our ice cream.
Vanilla- Adding vanilla extract will help to enhance the flavors in our recipe.
Large Marshmallows- We will be toasting these in the oven, but you can also just use 2-3 tablespoon of marshmallow fluff if you don't want your marshmallows to be toasted.

🔪 Instructions
Check out how to make toasted marshmallow mason jar ice cream with these simple step-by-step instructions:
Turn your oven onto high broil and line a baking sheet with aluminum foil.
Place 4 large marshmallows in the center of the pan and broil in the oven for 2-3 minutes or until toasted to your liking. Pay careful attention as they will go from golden to burnt really fast.
Once roasted, smash them in a bowl and set them aside.
Pour your heavy cream into the mason jar.
Add in the granulated sugar.
Add in vanilla extract and the smashed cooled marshmallows.
Close the lid to the jar tightly and shake well for 3-5 minutes or until the liquid has thickened.
Open the lid and dip a spoon in. Hold the spoon upside down. You want the liquid to not drip (one or two drips is fine) but it should cling well to the spoon.
Then close the lid to the mason jar and place it into the freezer for 3 hours before eating.
🍴 Recipe Tips
Making mason jar ice cream is so easy a kid can do it (and mine do). What you should remember is that a pint sized jar is perfect because there is plenty of space for the ice cream to move around and thicken as you shake the jar. Too small of a jar will result in less room so it will be much harder to mix everything up.
When you first start shaking the jar you will notice there is plenty of sloshing around, but depending on how fast or hard you're shaking the jar you may notice that within 1-2 minutes the liquid is moving less until there is no sloshing. You want to stop at this point. When you can noticeably feel and hear that the liquid is moving much less than it was, stop.
To overmix your ice cream will result in separation which is actually how you make your own butter...which is not what we are trying to do.
You will be able to open the lid, dip a spoon in, and hold it up. The spoon should remain coated in cream and have no drips (one or two small ones is fine, just don't let it roll off the spoon like chicken broth). Once your ice cream in a mason jar can do this, close the lid and place it in the freezer to chill for a few hours.
💭 FAQs
The two are practically the same thing and are easily interchangeable in recipes without any noticeable difference. The biggest difference is the fat content as one is easier to whip than the other, but both are great and will work in this recipe.
