A healthy crumble recipe? Yes, you read that right! A deliciously sweet and tart dessert, this plum crumble is the show-stopping way to finish off a healthy dinner, and won’t spike your blood sugars like other desserts would. At just 187 calories per serving, it’d be rude not to!

This healthy crumble is rich in colour, flavour and, best of all, nutrients. We chose plums as the star fruit of this dessert as they’re rich in vitamins, minerals, antioxidants and fibre which help to reduce your risk of various chronic illnesses and aid digestion. The insoluble fibre and sorbitol content in plums helps with constipation relief and healthy digestion, ideal after a hearty evening meal!  

We also developed this oaty crumble topping to be a healthier alternative to the traditional one made with butter, sugar and flour, but it’s just as tasty. Using rolled oats provides that crunchy texture we all know and love, with the added benefit of a decent dose of fibre, protein and antioxidants, including the fibre ‘beta-glucan’ which may improve insulin sensitivity.

This recipe is ideal for the whole family, and fun to make too! It can be easily adapted to whatever fruit you already have in, so feel free to substitute the plums for apples, pears or berries for a decadent dessert that is low in sugar and cost.
