This rhubarb crumble is a delightful, refined sugar-free treat that blends tangy rhubarb with sweet crumble topping in every bite! This timeless classic is the perfect comforting and refreshing dessert!
In a pan, heat maple syrup over medium heat for 2 minutes.
Add rhubarb chunks and until it becomes tender and starts to break down, about 5-7 minutes, on medium-high heat. Stir regularly.
Once cooked, transfer the mixture into a baking dish or loaf tin (9 x 4 inches).
In a bowl, combine the oat flour (or blitzed rolled oats), maple sugar and soft melted butter. Rub the butter into the dry ingredients with your fingertips until the mixture resembles coarse breadcrumbs.
Sprinkle the crumble topping evenly over the rhubarb filling.
Bake the crumble in a preheated air fryer (bake setting) at 170°C (340°F) for 7-10 minutes, or until the topping is golden and crisp. Alternatively, bake in a preheated oven at 180°C (350°F) for 15-20 minutes, or until the topping is golden and crisp.
Once baked, allow the rhubarb crumble to cool slightly before serving. Enjoy!
Notes
Adjust sweetness as desired: rhubarb is naturally tart, you can adjust the sweetness based on the tartness of your rhubarb.
Dice rhubarb stalks into uniform pieces: to ensure even cooking.
Serve the rhubarb crumble fresh: pair it with a drizzle of cream for extra indulgence.
