Low Carb Rhubarb Crumble

I don’t like wasting food grown in the garden or any food for that matter. The rhubarb was late growing and ripening. There was a lot of it but the stalks were thin. This recipe seemed the best use for it and I like crumble. It’s an easy recipe but I would say it gave four ‘not very big’ portions. The topping had good crunch and flavour. I enjoyed it very much with a splash of plant-based double cream. Enjoy!

  • 6 stalks fresh rhubarb, roughly chopped (the home grown rhubarb was quite thin)
  • 1 tsp granulated sweetener (used erythritol)
  • 2 tbsp water


  • ½ cup almond flour
  • ¼ cup flaxseed meal
  • 3 tbsp granulated sweetener (erythritol)
  • 2 tbsp unsalted butter (I used lactose-free butter)


  • Preheat the oven to 375F. 
  • Add the rhubarb, sweetener and water to a saucepan and simmer until rhubarb is cooked. 
  • Whilst the rhubarb is cooking, make the crumble topping by rubbing together the almond flour, flaxseed, sweetener, and butter, until breadcrumb like in consistency.
  • Test the rhubarb for sweetness and adjust if necessary, then spread it over the base of a small baking dish. 
  • Sprinkle the topping over the rhubarb and bake for 15-20 minutes or until golden brown on top and the rhubarb is bubbling through the topping.
  • Serve & enjoy!!
