Marshmallow ice cream brings together two textures that are especially fun in a frozen dessert: a smooth, creamy base and soft pockets of marshmallow throughout. Instead of relying on marshmallow flavoring alone, this recipe uses toasted marshmallows to give the ice cream a deeper flavor with light caramelized notes.
The trick is keeping the sweetness balanced. Marshmallows already contain plenty of sugar, so the ice cream base needs enough dairy and vanilla to keep the flavor from becoming one-dimensional. With a few simple steps, the ice cream stays creamy in the freezer and is much easier to scoop when you’re ready to serve it.

This recipe uses a cooked custard base, so it takes a little more attention than a simple no-churn mixture. The payoff is a particularly rich and creamy texture that works well with the chewy marshmallow pieces.
Ingredients You’ll Need
Mini Marshmallows
Mini marshmallows work especially well because they can be divided between the ice cream base and the mix-ins. Some are toasted and melted into the base, while another portion can be added later for little pockets of marshmallow flavor.
Egg Yolks
Egg yolks give the custard body and richness. They also give the ice cream a richer, smoother texture that makes every scoop feel creamy and satisfying.
Granulated Sugar
You need enough sugar to sweeten the dairy base and help with the texture, but there is no reason to make the base excessively sweet because the marshmallows contribute additional sugar.
Whole Milk
Whole milk keeps the mixture creamy without making the base feel excessively heavy. It provides the liquid portion needed to build the custard.
Heavy Cream
Heavy cream supplies additional milk fat, giving the finished ice cream a richer mouthfeel and helping it feel smooth rather than icy.
Vanilla Extract
Vanilla is more important here than it might seem. It rounds out the toasted marshmallow flavor and helps the ice cream taste more complete rather than simply sweet.
How to Make Marshmallow Ice Cream
1. Toast Part of the Marshmallows
Heat your oven’s broiler and arrange about 2 cups of mini marshmallows on a parchment-lined baking sheet.
Toast them briefly until the tops become golden brown. Watch them closely because marshmallows can go from lightly toasted to burnt very quickly.
You can also use a kitchen torch if you prefer more control over the amount of browning.
The goal is not to blacken the marshmallows. A little browning creates a deeper toasted flavor while leaving enough of the marshmallow intact to melt into the base.
2. Build the Custard Base
Whisk the egg yolks and granulated sugar together in a medium bowl until the mixture becomes smooth and slightly lighter.
While the milk warms in a saucepan over medium heat, let it come just to a gentle simmer. You don’t want it boiling. Slowly pour some of the warm milk into the egg mixture, whisking as you go so everything blends smoothly. This gradual addition is called tempering, and it helps raise the temperature of the eggs without cooking them too quickly.
3. Cook Until the Mixture Thickens
Reduce the heat and stir the custard continuously as it cooks.
The custard should thicken just enough to lightly coat the back of a spoon. Keep the heat at a moderate level and give it time to thicken rather than trying to speed things up. Gentle cooking gives you more control over the eggs.
Once thickened, strain the custard into a clean bowl. This removes any tiny pieces of egg that may have cooked during the process.
4. Add the Toasted Marshmallows
While the custard is still warm, stir in the toasted marshmallows along with the heavy cream and vanilla extract.
The warm mixture will soften the marshmallows and help them dissolve into the base. Stir patiently rather than expecting every piece to disappear instantly.
This is where the flavor starts becoming noticeably different from ordinary vanilla ice cream. The toasted marshmallow adds a deeper, lightly caramelized character.
5. Chill the Base Thoroughly
Cover the surface of the custard directly with plastic wrap or another suitable food-safe covering and refrigerate it until completely cold.
Give it at least 3 hours, although chilling it longer is fine.
Starting with a properly chilled base helps the ice cream machine freeze the mixture efficiently and creates a better final texture.
Do not move on simply because the mixture feels cool around the edges. The center should also be thoroughly chilled before churning.
6. Churn Until Thick and Creamy
Once the mixture is completely chilled, add it to your ice cream maker and churn it following the instructions for your machine.
The mixture should gradually become thicker and resemble soft serve near the end of churning.
Reserve a portion of the mini marshmallows for the final stage. Add them during the last couple of minutes so they remain recognizable instead of completely disappearing into the base.
This creates an important contrast: the toasted marshmallows contribute flavor throughout the ice cream, while the later additions provide little bites of marshmallow as you eat.
7. Freeze Until Firm
Spoon the freshly churned ice cream into a shallow, freezer-safe container. A wider container helps the ice cream freeze more evenly and makes it easier to scoop out when you’re ready to serve it.
Press parchment or freezer-safe covering gently against the surface to reduce direct exposure to air. Freeze for at least 4 hours, or until the ice cream reaches the firmness you prefer.
If the ice cream feels too firm to scoop, leave it on the counter for a few minutes to soften slightly before serving.
How to Get More Marshmallow Flavor Without Too Much Sweetness
The easiest mistake with marshmallow ice cream is assuming that adding more marshmallows automatically creates better flavor. If you enjoy naturally sweetened frozen desserts, our Honey Ice Cream recipe is another flavor worth trying.
It can actually make the dessert taste overly sweet before the toasted flavor becomes noticeable.
To get a more balanced result, focus on toasting rather than simply increasing the amount. Browning the marshmallows gives them a more developed flavor, allowing a moderate amount to make a noticeable difference.
Vanilla also helps. It does not make the dessert taste like vanilla ice cream; instead, it rounds out the sweeter marshmallow notes.
If you want a stronger toasted character, toast some marshmallows a little more deeply while keeping others lightly golden. That creates more variation in flavor without relying entirely on additional sugar.
Common Marshmallow Ice Cream Mistakes
Burning the Marshmallows
Broilers and kitchen torches work quickly. Stay close while toasting and remove the marshmallows as soon as they reach the desired color.
Overcooking the Custard
High heat can cause the eggs to cook into small pieces. Keep the temperature moderate and stir continuously.
Adding All the Marshmallows at Once
If every marshmallow is melted into the base, you may get plenty of flavor but little textural contrast. Holding some back for the end gives you both.
Churning a Warm Base
A warm mixture can take longer to freeze and may not develop the texture you want. Give the custard enough time in the refrigerator before churning.
Freezing It in a Deep Container
A very deep container can make the center take longer to firm up. A wider, shallower freezer-safe container is easier to work with. Once you understand how different ice cream styles handle ingredients and freezing, it becomes easier to adjust a homemade batch to the texture you enjoy. Our guide to Types of Ice Cream explains some of those differences in more detail.
Ways to Serve Marshmallow Ice Cream
Marshmallow ice cream is flavorful enough to serve on its own, but a few toppings can take it in different directions.
For a campfire-inspired dessert, add crushed graham crackers and a little melted chocolate. Chocolate shavings or mini chocolate chips work when you want something simple. For an even richer chocolate pairing, try our Chocolate Ice Cream Recipe for another homemade dessert option.
For a more understated serving, add a few toasted marshmallows and a light drizzle of chocolate sauce.
You can also serve a scoop alongside warm brownies or another chocolate dessert. The cold, creamy marshmallow flavor contrasts nicely with a warm chocolate base.
Storage Tips
Keep marshmallow ice cream in an airtight freezer-safe container with a sheet of parchment or freezer paper pressed gently against the surface.
For the best texture and flavor, enjoy it within a few weeks rather than leaving it forgotten at the back of the freezer.
Repeatedly allowing the container to soften and refreeze can lead to a less pleasant texture. For that reason, take out only the amount you plan to serve and return the remaining ice cream to the freezer promptly.
Frequently Asked Questions
Does marshmallow ice cream taste like vanilla?
It has a creamy vanilla background, but toasted marshmallows give it a deeper, sweeter flavor with lightly caramelized notes.
Can I use large marshmallows?
Yes, large marshmallows can be toasted and incorporated into the base, although mini marshmallows are easier to distribute and work better as mix-ins.
Can I make marshmallow ice cream without an ice cream maker?
A no-churn approach is possible, but the texture will be different from a churned custard-style ice cream. A churned method generally gives more controlled incorporation of air and mix-ins.
Why did my marshmallow ice cream become very hard?
Homemade ice cream can become quite firm in a cold freezer. Letting it rest briefly before scooping usually makes portioning easier.
Can I add chocolate to marshmallow ice cream?
Absolutely. Chocolate chips, chocolate shavings, or a chocolate sauce can complement the toasted marshmallow flavor without changing the basic recipe.
Conlusion
Marshmallow ice cream is more interesting than simply mixing marshmallows into vanilla ice cream. Toasting part of the marshmallows gives the base a deeper flavor, while reserving some for the end creates little pockets of texture.
The combination of a rich custard base, vanilla, toasted marshmallow, and a few carefully chosen toppings makes this a versatile homemade dessert. For another classic homemade option, try our Vanilla Ice Cream, a smooth and creamy favorite that pairs well with almost any dessert. Give the base enough time to chill, watch the marshmallows closely while toasting, and let the finished ice cream soften slightly before scooping for the best experience.
