Plum Crumble Cake (Vegan, Gluten-Free) – Fluffy & Fruity
The Vegan Monster
I love summer - and I love it even more when friends share their harvest. That’s exactly how this Plum Crumble Cake happened: juicy plums, a fluffy crumb thanks to hazelnuts in the dough, and a crunchy crumble on top. It’s hard to believe it’s vegan, gluten-free, and low in sugar. And if you’re in the mood to switch things up: walnuts work beautifully instead of hazelnuts, too.

27×17 cm baking tray
Baking paper / parchment
frying pan (to roast hazelnuts)
food processor / grinder (for hazelnuts)
mixing bowls (medium + small)
- approx. 500g plums halved
For the dough:
- 140 g hazelnuts (1/4 cup will be needed for the crumbles)
- 2 ripe FAIR-TRADE bananas (300g)
- 90 g sweet sorghum flour
- 2 teaspoon baking powder
- 1 teaspoon baking soda
- 1 pinch salt
- 1/2 cup water
For the crumbles:
- 30 g of the ground up hazelnuts
- 65 g sweet sorghum flour
- 1 teaspoon ground cinnamon
- 30 g coconut oil
Preheat the oven to 190°C. Roast the hazelnuts in a frying pan, stirring constantly until the skin starts to fall off. Take off the heat and let cool down.
Rub off most of the peel and then grind the hazelnuts to fine crumbles. Remove 1/4 cup of the ground hazelnuts, it will be needed for the crumbles. Transfer to a medium sized bowl.
Add the sorghum flour, baking powder, baking soda and salt and stir well.
Mash the bananas in a small bowl until they are a fine cream. Add the mashed bananas and the 1/2 cup water to the dry ingredients and mix well to combine. Don't stir too long.
Transfer to the baking tray and spread evenly. Place the plum halves on top of the dough.
Mix the ingredients for the crumbles in another small bowl. Sprinkle the crumbs with your hands over the plums.
Place the tray in the oven and bake covered for approx. 20 minutes at 190°C. Remove the cover for the last 10 minutes (depending on oven type).
