This sugar free crumble has a deliciously crunchy topping, with naturally sweet fruit beneath. A no sugar crumble topping is super easy to make. It complements all types of fruit crumble, although I think sugar free apple and cinnamon crumble is simply the best.
Melt the butter in a pan over a low heat. Stir in the ground cinnamon and optional sweetener if using.
50 g butter, 1 teaspoon ground cinnamon, 1 tablespoon sweetener, see notes below
Add the oats to the melted butter and stir until mixed and clumps start to form.
150 g porridge oats
Wash, prepare and cut your fruit into bite-sized pieces. Add to an oven proof baking dish.
500 g fruit
Add the sugar free crumble topping, and spread over the fruit base.
Bake for 30 minutes in the preheated oven until golden and crunchy. Pierce the crumble with a sharp knife to ensure that the fruit is cooked through. If necessary, pop the crumble back in the oven for an extra 5-10 minutes.
Notes
You can replace up to half of the oats with flour if preferred for a less crunchy topping.
Depending on your taste and the fruit you are using, you may want to add some sweetener. You can use a liquid sweetener such as honey, maple syrup, date syrup or unsweetened apple sauce. Add a tablespoonful to the melted butter. Alternatively, use a powdered sweetener such as stevia or xylitol.
If you are making the crumble with soft fruit such as berries, peaches or plums, you'll find that quite a lot of juice runs out of the fruit as it cooks. It's nice to thicken the juices into a syrup. Either stir a tablespoon of cornflour or ground almonds into the fruit before adding the topping.
If you want to reduce the natural sugars in the recipe, use a lower sugar fruit such as berries.
