Plum Crumble Cake

Plum Crumble Cake

A delicious and easy vegan plum crumble cake – a vanilla sponge with juicy cinnamon flavoured plums topped with crispy crumble.

I had almost forgotten about plum crumble cake until a recent trip to Germany. Thanks to my wife’s uncle I managed to pick a few plums from his tree over the weekend and thought I would have a go at making a vegan version this time.

The next day we headed over to the in-laws for lunch and no sooner had it been placed on the table it was all gone. I think it was a success 🙂

    Recipe highlights

    • Ease: Super easy.
    • Great for: Gatherings and comfort food.
    • Taste: Sweet and fruity.
    • Texture: The sponge is moist and fluffy, filled with juicy plums and topped with crispy crumble.

    Recipe tips

    • Use plums that are just ripe. If you use over ripe plums they will just be a mush in the middle. Unless you like that 🙂
    • I prefer to use metric measurements with a digital scale rather than cup measurements. I recommend this as you will get far better, more consistent results weighing your ingredients. It is also easier and less messy than cups! 🙂

    Vegan sponge

    • 150 g plain or all-purpose flour (BL55)
    • 30 g cornflour (US -cornstarch) (cornstarch)
    • 100 g soft brown sugar
    • 1 tsp baking powder
    • 1 tsp vanilla extract, sugar or 1/2 tsp of vanilla paste
    • 75 ml neutral-tasting oil (coconut, vegetable or sunflower oil)
    • 150 ml non-dairy milk (almond, oat, rice or soy milk) (room temperature)
    • 1 pinch fine sea salt


    • 500 g fresh plums
    • 30 g soft brown sugar (2 tbsp)
    • 1/2 tsp ground cinnamon

    Crumble topping

    • 100 g plain or all-purpose flour
    • 50 tsp soft brown sugar
    • 50 ml coconut oil


    • Crumble topping: In a large bowl, mix together the flour, sugar and cinnamon with a fork until well blended.
    • Make a well in the center and pour in the coconut oil. Gently rub the ingredients together with your fingertips until the crumble looks like chunky breadcrumbs. Don't over mix.
    • Spread onto a small baking sheet lined with parchment paper, cover with cling wrap and chill until you are ready to use.
      Chilling will harden the coconut oil and will make the crumble crispier.
    • Pre-heat oven to 180°C fan / 400°F / Gas 6.
    • Line a baking tin with baking parchment and leave a side until ready to use.
    • Plums: Wash and then cut the plums in half lengthways removing the stones. Place them in a bowl and mix in the cinnamon and brown sugar and leave to macerate.
