My easy rhubarb and vanilla cake with buttermilk is a delicious cake with chunks of sharp sweetness from the rhubarb and the tang of buttermilk, with the sweetness of vanilla.
Lovely for a special occasion or weekend bake, or everyday when you have a rhubarb patch at home.
Rhubarb in baking
I love it when rhubarb season arrives, it really shows that spring is finally here.
As a child we grew rhubarb on our allotment, and stewed rhubarb and rhubarb crumble have always been among my favourites. What is your favourite rhubarb dish?
Rhubarb also goes really well in cake of course. Here I’ve made a vanilla-flavoured rhubarb buttermilk cake, topped and filled with roasted rhubarb.
The buttermilk makes the sponge lovely and soft with a great flavour, and slightly denser than a traditional sponge.
This cake is really easy to make, just remember to roast your rhubarb a little earlier in the day.
I make this cake regularly now when rhubarb is available as it is a hit with all the family. You can’t beat a slice of homemade cake with a cup of tea can you?
Ingredients
Use this list as a handy shopping list or a guide when gathering together the ingredients to make your rhubarb cake. For quantities please refer to the recipe card at the end of the post.
- butter – I tend to use unsalted as that is the kind of butter I keep in the fridge, but salted will work fine too.
- caster sugar – I use golden but normal white caster sugar works just the same
- eggs
- self-raising flour
- vanilla bean paste – can swap for vanilla extract, avoid vanilla essence though as it has a synthetic taste
- buttermilk – if you don’t have any you can easily make some by mixing milk with a little lemon juice and leaving to thicken for 5-10 minutes.
- rhubarb – 3-4 large stalks ideally
Step by step
- Roast the rhubarb by washing it, cutting into small pieces (around 5-6 cm in length) and sprinkling over 50 g caster sugar, then roasting for 15 minutes in a foil-covered dish. Then remove the foil and roast for 5 minutes more. Leave to cool.
- Cream together the butter and sugar until light and fluffy.
- Add the vanilla bean paste and then the eggs, one by one.
- Fold in some of the flour, then add some of the buttermilk. Add each in stages and mix in between until all fully added.
- Place half of the cake mixture in a deep 8-inch/20 cm springform cake tin sprayed with cake release spray.
- Place some pieces of the roasted rhubarb on top, then add the rest of the cake mixture on top of it.
- Smooth the top then place more of the roasted rhubarb on top (you may not want to use it all, I had some left over).
- Bake for 50-55 minutes at 180 degrees Celsius / 350 F (preheated oven), or until the cake is golden brown and fully cooked in the centre – check using a cake tester.
- Allow to cool then enjoy!

Your cake looks delicious and I like your idea of roasting the rhubarb first.. I like a slightly denser cake and I definitely like rhubarb cakes. I made one the other day, but haven’t posted it yet. And last night I had rhubarb crumble – oh heaven!

Yum! I love rhubarb! That reminds me, there is a huge rhubarb plant in the garden of this house I’m currently house sitting. I’ve forgotten to check it this spring! Now I’m inspired, thank you!

Excellent stuff. The advantages of house sitting!

bakingqueen74 says
Great, let me know if you do!
Mary Anne says
would it work with apple instead of rhubarb?
bakingqueen74 says
Should do! No need to roast the apple first I’d have thought.
Fuss Free Helen says
Gorgeous cake. It would be great warm from the oven with lots of lovely home made custard too.

Thanks Helen. Great idea, will do that if it gets chilly again tomorrow!
