Flourless Rhubarb & Apple crumble

Flourless Rhubarb & Apple crumble

Whether you want a flour-full or flourless crumble recipe, this rhubarb and apple crumble recipe is a winner!

I’ve substituted the flour with oats and ground almonds and it absolutely worked. It gives the crumble a really great texture, not to mention flavour and richness.

This recipe is SUPER SIMPLE and nutritious:

Oatmeal: High in many vitamins and minerals and also a Low GI & high fibre food that keeps you fuller for longer.

Almonds: Rich in magnesium, vitamin E, healthy fats and fibre.

Rhubarb: High in Vitamin K and fibre.

I used Rhubarb and apple because they are in season at the moment and Im making a conscious effort to buy and eat more in-season foods 🙂 But you can really use any kind of fruit for this. Berry crumble, peach crumble, plum crumble – whatever fruit you fancy most!
