Ingredient List for Vegan Oat Ice Cream

The exact amounts of each ingredient are indicated in the recipe card at the end of the post.

You will also need some cold water to make the vegan ice cream base. Yes, you read correctly, water! You do not have to use up your almond milk or other plant-based milk to make the ice cream base. Instead, the rolled oats and water create a silky oat cream, perfect for making the best vegan vanilla ice cream!

If you prefer to use plant-based milk in place of the water, though, go right ahead! Use any non-dairy milk you prefer, such as hemp milk or oat milk.

Tip: Vanilla

The better the vanilla, the better the vanilla flavor! But then again, vanilla extract is expensive, so use what you can afford. For a more pronounced vanilla flavor, consider using vanilla bean paste, or scrape the seeds from vanilla beans.

Optional Ingredients

1. Salt

I strongly recommend adding a bit of salt, too. It enhances the flavors to a higher level. I even add an extra pinch when using salted, roasted sunflower seed kernels.

2. Clear Alcohol

Adding an ounce of clear alcohol, such as vodka or gin, to the ice cream base prevents ice crystals from forming, which helps to keep the ice cream creamy after freezing. The recipe is still creamy and delicious without it.

Tip: Use Roasted or Raw Sunflower Seed Kernels

You can use raw sunflower seeds or roasted sunflower seeds to make this easy ice cream.

Raw sunflower seeds produce a neutral-flavor, traditional vanilla ice cream. Roasted, salted sunflower seeds are easier to find in most general supermarkets. They produce a more deeply flavored, toasty ice cream (I love it).

Step by Step Directions for 4-Ingredient Vegan Oat Ice Cream

Note that the complete directions are also in the recipe card below.

Step One: Blend All of the Ingredients

Place all of the ingredients–the water, rolled oatssunflower seed kernelscoconut sugar, and vanilla extract–in a high speed blender container. Also add the salt and/or clear alcohol, if using.

Blend the ingredients on high speed until completely smooth and velvety in texture. You will need to stop the blender a few times to scrape down the sides of the container. Add more water, as needed.

Step Two: Churn in Ice Cream Maker

Pour the blended mixture into the bowl of your ice cream maker and churn according to the manufacturer’s instructions. Churn until the ice cream resembles loose soft serve ice cream.

Step Three: Freeze Until Firm

Spread the churned ice cream into a freezer-safe container (a loaf pan works great) and tightly cover.

Freeze the ice cream for four to eight hours, or until very firm. The depth of the container will make a difference as to how fast the ice cream will freeze (i.e., shallower=faster, deeper=slower).

The ice cream will be VERY hard once frozen (i. e., not immediately scoopable, like tradional ice creams). Not to worry! This is exactly as it should be. 

Step Four: Thaw Slightly & Scoop

Thaw the ice cream at room temperature for about 15 minutes to soften it enough to scoop. Alternatively, microwave the ice cream (so long as it is in a microwave safe container) for 10 to 15 second intervals until softened. Now it is scoopable!

Scoop or spoon into cups, bowls, or atop cones, as desired.

What is the Taste & Texture of Vegan Oat Ice Cream?

Delicious! This is a rich and creamy ice cream. 

Coconut sugar gives the ice cream a rich nuanced flavor without any addional flavors added. Still, the smidge of vanilla adds great flavor depth. The better the vanilla, the better the vanilla flavor of the ice cream. But use what you have!

How Should the Ice Cream Be Stored?

Store the ice cream in a freezer-safe container in the freezer for up to 3 months.

Can I Make the 4-Ingredient Vegan Oat Ice Cream without an Ice Cream Maker?

Yes, you can!

Pour the ice cream base into freezer safe container and freeze until hard, as directed above. That the ice cream at room temperature for about 30 minutes. Use a spoon or scoop to scrape the ice cream into creamy scoops.

What Is a Good Substitute for Coconut Sugar?

You can sub an equal amount of lightly packed brown sugar, or use the granulated sugar of your choice. You can also use 1/2 cup (118 mL) maple syrup.

Can I Make Different Flavors of Ice Cream with this Recipe?

Yes! This vegan oat ice cream has a neutral flavor that can be varied in many ways. It is a perfect base for mix-ins and flavors like:

  • zests and extracts – try lemon, lime or orange zest, almond extract, or mint extract 
  • coffee or espresso – replace some of the water with (cold) strong coffee or espresso
  • chocolate chunks or chips
  • chopped seeds or nuts
  • chopped cookies
  • fresh fruit purees and syrups

Hard mix-ins should be added to the ice cream immediately after churning. Fold them into the ice cream before spreading the churned ice cream in a freezer-safe container.

What Can I Use in Place of Oats?

There is no direct substitute for oats for this 4-Ingredient Vegan Oat Ice Cream. However, I have other nondairy ice cream options that can be found in the search bar (some are listed below).None of them contain oats!

Can I Make This Non-Dairy Ice Cream in a Food Processor?

I do not recommend it. A high-speed blender is the best option for producing a creamy texture. The oats and sunflower seeds will not break down to a smooth, velvety texture enough in a food processor

Additional Time: 4 hours
Total Time: 4 hours 5 minutes

Creamy 4-ingredient vegan oat ice cream, made with no cashews and no coconut! Make the base for the ice cream in a blender in about two minutes, then use a churn or no-churn method.


  • 1 and 2/3 cups water
  • 1 cup (100 g) rolled oats (certified gluten-free, as needed)
  • 1 cup (120 g) raw sunflower seed kernels (roasted will also work)
  • 1/2 cup (72 g) coconut sugar (see options, below)

  • Optional: 1 ounce vodka or gin (keeps ice cream creamy)
  • Optional: 1/4 teaspoon salt

Why Alcohol is Included as an Optional Ingredient: A small amount of alcohol helps the ice cream to remain maintain a creamy texture and prevents the ice cream from freezing so solidly. The ice cream is till delicious without the alcohol!

Storage: Store the ice cream in an airtight container in the freezer for up to 3 months.

Sunflower Seed Substitution: An equal amount of raw cashews can be used in place of the sunflower seeds.

How to Freeze Faster: The depth of the container will make a difference as to how fast the ice cream will freeze (i.e., shallower=faster, deeper=slower). So to freeze more quickly, place in a shallow dish.

Sugar Options: An equal amount of natural cane sugar. regular granulated sugar, brown sugar, or maple syrup can be used in place of the coconut sugar.

I am so glad that I have found your website. I look forward to trying a bunch of nice recipes. Question for this ice cream, please. Why does the alcohol have to be clear? Cannot it be any alcohol as long as it is 40% or so? Thank you.


Saturday 7th of October 2023

Hi Alina! I am so glad that you found my site, too—welcome! Thank you for asking that about the alcohol. I will modify it, because you are correct: you can use other spirits with a similar alcohol content (e.g., whiskey, rum, brandy, tequila). They will add flavor. If you do not want the flavor of the alcohol, use clear spirits , like vodka. Cheers!

Hi Camilla, You are a genius. This ice-cream is amazing. Simple. Ordinary ingredients. Delicious. And gluten and nut-free!!! OMG. My son is allergic to nuts (including coconut) and my daughter is gluten-free. Wow, you made a dream come true for us! Thank you from the bottom of our hearts (and stomach!). You deserve to win awards for your amazing recipes.

Joni, if I could do a backflip, I would, because your comment brings me so much joy! I love that your kiddos can share the same sweet treat ❤️ thank you so much for the kind compliments!

Hi. The ice cream tastes a bit bitter is it bcoz of oats as I can feel the taste of oats


Sunday 6th of August 2023

Hi Karishma,

I suggest toasting the oats and sunflower seeds (or use roasted sea flower seeds). I sm not quite sure what you mean by “feel the taste”—- just want to make sure the ice cream is completely blended until smooth (so ingredients are completely broken down and creamy)

SO glad to have found you! It was your pumpkin seed tofu that brought me to your website...

Ive got histamine intolerance and was vegan for 12 years before developing this and other sensitivities to almost ALL vegan protein - Soy, cashew, almond, peanut, lentils, all pulses, sunflower seed. It's really difficult to navigate with as almost all ready-made vegan food has some allergen of mine in it.

However, I am hopeful... I just made the Pepeta tofu and can't wait to cook with it!

Question: Is there a possible substitute for sunflower seeds for this ice cream recipe?

Thanks so much!


Sunday 6th of August 2023

Hi Clover Honey! I’m so glad you found my site, too! Since you can eat pepitas, you can definitely use those as a substitute here. Either raw or toasted. Hemp hearts will also work (I have a hemp heart strawberry ice cream on the site, too) ????
