Vegan Custard

Did you know you can make vegan custard in only 5 minutes with just 4 ingredients? Let me show you how to make a super easy thick, pourable custard sauce without eggs or dairy!

Overhead Shot of custard

At long last, my eggless custard recipe is finally here!

I have been going on about making it for the longest time but just had so many recipe ideas in my head that I didn’t get around to it until now!

I must first start by saying that if you’re from the USA, this is not a vegan alternative for custard as you know it. I believe over there it’s known as egg custard or baked custard and as delicious as that looks, the UK version is a little bit different.

Here, it’s more of a custard sauce and we use it (usually warm) to top desserts such as apple crumble.

Oh my gosh, it’s SUCH a good addition to hot desserts in the winter. *drools*

I know there are some egg-free custard alternatives out there already (did you know Bird’s custard powder is vegan-friendly if you make it with dairy-free milk?!) but I’m adamant that nothing beats the homemade version!

No eggs?

Typically when you make custard sauce you add eggs, which gives it thickness. When you take away the eggs, you need something to replace that to give it the same consistency.

And this is where cornflour (or cornstarch for my US people) comes in handy! It’s such a useful ingredient. It thickens liquids and gives it that pourable consistency that we’re after here.

I’ve been using cornflour quite a lot recently and have been surprised to find that you can make so many recipes with very similar ingredients.

If you check out my lemon curd recipe and the caramel in my banoffee pie, you’ll see the ingredients are almost identical with a few subtle changes. It’s like magic!

How to make vegan custard from scratch

Aside from a small saucepan and a wooden spoon, all you will need is these 4 things:

  • Cornflour (cornstarch)
  • Plant-based milk (I use always use unsweetened organic soy for my recipes but you can use coconut milk, oat milk, almond milk, or basically whatever other vegan milk you like)
  • White sugar (I used caster sugar)
  • Vanilla extract

Step 1:

Measure out all of the ingredients. You’ll need 4 tablespoons of cornflour, 600ml of plant-based milk (around 2 + 1/2 cups), 90g of caster sugar (1/2 cup), and 2 tablespoons of vanilla extract (not teaspoons).

Step 2:

Mix the cornflour with 4 tablespoons of the plant-based milk in a small bowl until smooth. Add that mixture to the rest of the plant-based milk and mix well.

Mixing soy milk with corn flour

A common problem when cooking or baking with cornflour is that it clumps together easily. If you add it to a large amount of liquid or anything hot, the lumps will be super hard to get rid of. Mixing it in a small amount of liquid first helps to prevent this.

Step 3:

Add the milk and cornflour mixture to the saucepan along with the rest of the ingredients. Turn the heat up high and stir continuously until it thickens like a custard sauce.

What makes it yellow?

I used a tiny pinch of turmeric to make it more yellow. Normally I prefer using food colouring but in the case of this recipe, it made it look like radioactive waste. So turmeric it was.

a pinch of turmeric added to the pot

I had always been a bit afraid of using turmeric as food colouring because I find the taste to be SO strong and didn’t want to ruin my desserts with that flavour. But the amount I used was so minuscule that it didn’t affect the final taste at all.

Because the flavour is so potent, I’d recommend only using a tiny amount of turmeric at a time. Mix it in first and if you’d like a deeper colour, add some more.

Of course, this step isn’t totally necessary and is purely for aesthetic purposes. You can skip it altogether and just have a creamy white coloured custard. It’ll taste amazing all the same!

Ways to use eggless custard

I created this recipe mainly due to the fact that I was craving it when baking my old favourite school dinner desserts, caramel tart and vanilla sheet cake. So I’d definitely recommend pairing it with either of those.

You can also use it to make a show stopping vegan trifle or pair it with any of these desserts:

Alternatively, you could serve it alone as a dessert on its own. It tastes great hold or cold! I’m also planning to use it for some more upcoming recipes so keep your eyes peeled for more ideas.

How long will it last?

This particular recipe will taste best if eaten within 2-3 days. It should be stored in the fridge in a covered bowl or airtight container. Mix well before use.

My custard is too runny or too thick. How can I fix it?

If the custard becomes too thick, add more plant-based milk while it’s still on the heat and mix well. Add 1 tablespoon at a time to determine the thickness before adding more.

If it’s too runny, add some more cornflour a little at a time. You will need to mix it with a small amount of cold water before adding it and you’ll need to continue heating the custard to allow the cornflour to do its job.

I’d recommend starting with 2 teaspoons of cornflour mixed with 2 teaspoons of cold water. Mix it into the custard and stir over high heat for a minute or two. Repeat as necessary.

Can I reheat it?

Yes! To reheat, simply place it into a saucepan over low heat and stir constantly until warm. If it gets too thick, just add a little plant-based milk to loosen it.

How much egg-free custard will this make?

With the recipe listed below, you’ll get around 350ml (or 1 + 1/4 cups) of custard. Feel free to multiply or divide the ingredients as required.

Hi, is the recipe supposed to call for 2 tablespoons of vanilla? Seems like a lot


Sunday 8th of May 2022

Hi Pam, yes, I found 2 tablespoons a good amount for this recipe because the cornflour tastes quite strong. You can start with a little vanilla and add more to your taste :)

Hi there, I love custard and will make this tomorrow.

Hi Jeanne, hope you enjoy! :)


Friday 5th of February 2021

Can you add lemon juice to it to make a lemon flavored custard?


Friday 5th of February 2021

Hi San! I think lemon zest would be best as it gives a stronger flavour. You might need a little more milk to thin it out a bit :)


Sunday 16th of August 2020

Hi, I had a question about your recipe. Do you mean 4 tablespoons of corn flour or 2 1/2 cups of corn flour?


Sunday 16th of August 2020

Oops, sorry! I put that in the wrong place, it was meant to say 2+1/2 cups soy milk. Thank you for pointing that out! xo
