Rhubarb & Oat Crumble Cake

We love the beginning of rhubarb season its so exciting to taste something so delicious out of the garden after the long Winter months! We love a good old fashioned Scottish rhubarb crumble and thats what makes this cake so good! It’s like a Scottish crumble but cake!

Traditionally we would make a delicious crumble with a sweet oat and flour topping but we are in love with this delicious rhubarb crumble cake it goes so well with custard or just quite simply on its own out of the oven.

If you like the sound of this delicious rhubarb crumble cake then you may also like some of my other delicious Scottish seasonal treats. We love a classic traditional Scottish jam sponge for pudding and it works really well with custard. A traditional Scottish clootie dumpling is also one of our favourite Scottish puddings and is also quite delicious enjoyed as a slice for breakfast.

Tips for making this recipe:

  • Seasonally available fresh rhubarb is best for this recipe but you could use very well drained tinned rhubarb if your out of season or its not available.
  • You can vary the topping on the crumble and try chopped nuts or even almonds instead of oats. Oats work best in my opinion and adds a delicious Scottish touch to the cake.
  • Traditional rhubarb crumble is quite often served up with custard in our house and this crumble cake works really well with custard or whipped cream. Its really delicious just on its own too fresh out of the oven.
