Healthy Rhubarb Crumble Recipe. Vegan + Gluten Free

Rhubarb crumble has always been one of my favourite puddings! So I decided to do my own take and create a rhubarb crumble recipe that was vegan, gluten-free and containing no refined sugar.

The rhubarb is cooked until sticky and tender topped with a sweet oat crisp.  Skipping on the butter, sugar and wheat flour this healthy rhubarb crumble recipe can be enjoyed guilt-free without feeling heavy and bloated afterwards!

Sweetened only with maple syrup with oats, flour and coconut oil forming the crumble. This doesn’t compromise on taste or texture, it tastes just like the real deal.

The ultimate summer dessert. Perfect served warm with some coconut yoghurt.

Health Benefits of Rhubarb

Rhubarb is high in antioxidants which are good for heart health. Rhubarb is also a good source of vitamin C that helps boost immunity and increases the absorption of iron.  Rhubarb also stimulates the growth of good bacteria in the digestive system.
