Pre-heat the oven to 200°C.
Place all fruit into an ovenproof dish and add 100g granulated sweetener, cornflour, lemon juice and mix well.
In a mixing bowl add almond flour, 20g granulated sweetener, oats, reduced fat spread and a pinch of salt. Using your fingers, rub together until it resembles breadcrumbs then add egg and mix well. The mixture should be crumbly but not too dry.
Using a tablespoon, add large spoonfuls of the mixture onto the fruit, leaving a few gaps for the fruit to bubble through.
Place in the oven and bake uncovered for 20-25 minutes, until the topping is golden and the fruit is bubbling.
