Self Saucing Rhubarb & Custard Pudding
A light airy vanilla sponge blanketing a layer of rhubarb in a pool of custard, complete with tips to the perfect Self Saucing Rhubarb & Custard Pudding!
My love of an easy to make ‘as if by magic’ self saucing pudding set me wondering. What if I could incorporate one of my favourite classic British flavour combinations, rhubarb and custard ? Remember those rhubarb and custard boiled sweets ? So sharp, yet so sweet and creamy.
After a few trials experimenting with quantities and methods, I finally cracked it! A tender vanilla sponge over a layer of sharp rhubarb revealing its own pool of creamy custard beneath.
It makes a delicious alternative to a rhubarb crumble and you don’t have to make any custard.

If you haven’t made a self saucing pudding before and this recipe goes against how you might usually bake, don’t worry. Sprinkling sugar and custard powder over a batter and pouring hot milk on the top looks and sounds rather strange but be patient, it works. I’ve included a few tips to help you make the best rhubarb and custard pudding.
If your tastebuds are not keen on rhubarb or there is a rhubarb shortage – seasonal or otherwise – this recipe also works well with apples or blackberry and apple.

What Do I Need ?
This recipe is perfect for when you’ve got plenty of rhubarb growing. The rest of the ingredients are pantry and fridge staples.
Sponge Batter Ingredients
- Plain flour or all purpose flour
- Baking powder
- Caster sugar or superfine sugar if you’re in the US.
- Butter – I used salted butter but you can use unsalted, just add half a teaspoon of salt to the mix.
- Milk – I used full fat milk.
- Vanilla extract
- Eggs – I used medium eggs. If you’re in the US use large eggs (egg size categories vary from country to country)
Custard Sauce Ingredients
- Custard powder – I used Bird’s Original Custard Powder
- Caster sugar
- Milk
- Butter

How To Make Rhubarb Pudding
Firstly, melt the butter for the batter mix and leave to one side.
Arrange the sliced rhubarb over the base of a large well greased baking dish (I used a shallow 2 litre / 8 cup dish). Sprinkle with sugar.
Bring your milk and butter for the custard sauce to boiling point before you start the batter mix.
To make the batter mix, sift all the dry ingredients into a large mixing bowl.
Whisk the milk, vanilla extract and beaten eggs into the cooled melted butter. Pour onto the dry ingredients and briefly whisk until smooth.
Pour the batter evenly over the rhubarb.




To make the custard sprinkle the custard powder and caster sugar over the batter.
Slowly pour the hot milk and butter over the back of a tablespoon onto your pudding.
Bake in the oven for approximately 35 to 40 minutes until the batter is set.
Tips For The Best Self Saucing Pudding
- Baking dish – Use a 2 litre (8 cup) capacity baking dish that has been well greased with butter. This helps prevent the pudding from burning or catching.
- The key to a perfect pudding is to handle with care and don’t over mix.
- Making the custard – to ensure even distribution of the custard and caster sugar, sieve them together in a bowl and mix before sprinkling over the top of the pudding batter.
- Pouring the hot liquid over the back of a spoon as close to the pudding as you can will prevent the liquid from falling too heavily and help keep a light sponge.
- Don’t over bake – it’s important not to over bake the pudding as you don’t want the custard to dry out and disappear! Once the top of the rhubarb pudding is cooked to the touch, it’s ready.
- Let your pudding stand and set for at least 5 minutes before serving as this allows the sauce to thicken up.
How To Serve
Self Saucing Rhubarb and Custard Pudding is best served freshly baked. It’s an all in one pudding so you can take it the table just as it is and serve.

How To Store And Reheat
If you do have any leftovers – you can keep it in the fridge for up to three days. I wouldn’t recommend reheating in the oven as the custard will dry out. Pop a serving in a bowl and microwave for about 20 seconds.

Be still my beating heart. This pudding is fan-flippin-tastic. I have some rhubarb in the freezer from last year – not only do I absolutely love the look of this pudding, I want to eat it AND my hubby will love me even more than he does already! Making this will be a fantastic treat for my family. Thank you for such a brilliant recipe, as always. Sammie xx
Thanks for your lovely comment Sammie, I hope you and your family enjoy my rhubarb and custard pudding xx
Oh my word! I want to dive straight in there with my spoon. It looks absolutely amazing. #BloggerClubUK
Thanks Georgina, it’s my favourite rhubarb pudding and it’s so easy to make too.
It looks yummy, but I’ll just have to drool over the pictures because it’s not sugar, dairy and gluten free 😉 #bloggerclubuk
Thanks Emma for taking time to come and visit my blog 🙂
Oh we are planning some rhubarb cooking today – This looks and sounds lovely – will pin and try it soon 🙂
Thanks Sarah, hope you like my rhubarb and custard pudding as much as we do 🙂
To be honest I have never tried Rhubarb, my dad always loved it, but for some reason I was not willing to taste it I will have to try now that I am all grown up because this sounds amazing #BloggerclubUK
Thanks for popping by, I hope you do get to try some rhubarb & that you like it. Don’t forget you could always make a blackberry and apple version.
Lovely pudding. Is it really 150g sugar to go with the custard powder?. It was very sweet
Thanks Maria. It is a lot of sugar, I think we have a rather sweet tooth here at the Kitchen Shed. Self saucing puddings tend to use a lot of sugar in the sauce, I’m going to try it with 100 g sugar & I’ll let you know how I get on.
You cannot beat a self saucing pudding can you? Simply lovely!
Thanks Helen, we’re finding self saucing puddings are quite addictive. A good job the rhubarb season is about over 🙂
Yum! I love rhubarb, I’ve just started this year trying to grow some too. I will definitely be trying this, sounds delicious 🙂
Thanks Mother Mands, hope you enjoy the pud as much as we do 🙂
Wonderful recipe! I live in a part of the U.S. where it is very hard to grow rhubarb and you can only get it in the store for a couple of weeks every spring. The apples are a great tip!
Marcey
Thanks Marcey, I’ve found it much harder to grow rhubarb here in France but I’m so glad the rhubarb patch has eventually started growing well, I would really miss being able to get hold of rhubarb easily. Hope you enjoy the self saucing apple version. Let me know how you get on 🙂
