Deliciously Moist Rhubarb Sponge

Questa ricetta è disponibile anche in italiano

Gorgeous Rhubarb sponge cake paired with a quick and fragrant orange flavoured custard: a dessert that is perfect both in the morning or for an afternoon tea.

Hello there!
Are you a rhubarb lover?
My husband and I are literally in love with this baby, especially in desserts! From crumble to pies to sponge, the sourness of the rhubarb perfectly matches the sweet of desserts, making it a perfect combo for those who doesn't love particularly sweet puddings!
A few days ago I baked this gorgeous Rhubarb sponge cake which I paired with a quick and fragrant orange flavoured custard.
This dessert is perfect in the morning if you fancy a sweet breakkie, for an afternoon tea or to end a meal with your loved ones.

Deliciously Moist Rhubarb Sponge Recipe

Ingredients:

...for the sponge...
250 g Fresh Rhubarb
150 g All Purpose Flour
150 g Demerara Sugar
140 ml Plant Based Milk (Oat)
50 g Ground Almonds
60 g Vegetable Oil (Sunflower)
2-5 g Vanilla Extract or Sugar
1 tablespoon Apple Cider Vinegar
1 teaspoon Baking Powder
1 pinch Salt
...for the orange custard...
250 g Plant Based Milk (Soy)
50 g Orange Juice
25-40 g Icing Sugar (according to your taste)
20 g Corn Starch

Method:
Preheat the oven at 180° C (350°F).
In a bowl combine flour, ground almonds, sugar, baking powder and salt (all dry ingredients basically).

Incorporate vegetable oil, apple cider vinegar and plant based milk, mix all the ingredients together then add the fresh rhubarb chopped in chunks of roughly 1 inch each.

Combine well then pour into a 18-20 cm (7-8 inches) diameter baking tray coated in baking paper and bake for 30 minutes.

In the meantime let's prepare the simple custard.

In a pan add corn starch and sugar. Gently combine the orange juice, then top with the plant based milk.
Cook on low heat constantly stirring with a spatula until it thickens (3-4 minutes).

Custard is ready to be served.

Once the cake is ready (I advise to check if it's cooked inside with a skewer that should come out dry) allow it to cool down at room temperature for at least 30 minutes before serving it.

Serve with warm orange custard and maybe a cosy cup of your favourite tea.

I think your measurements are off. I adjusted as well as I could and the cake tastes ok. It's not overly sweet, which I like, but the custard had very little flavour.

  Thank you for your comment, I double checked with my notes and the recipe measurements seem ok.
  What measure did you use? Grams or cups?
  I always recommend to use grams in baking, as cups are not as precise.
  Anyways, I was planning to make this cake soon with my homegrown rhubarb, so I'll also do another taste test.
  I'm glad you found it tasted ok 😉
  Have a nice weekend.
