Preheat the oven to 180°C.
Cut the figs into thin circles, then lay them in a baking dish, overlapping each other. Pour over the juice or syrup, then scatter the sugar, chopped walnuts and half of the cinnamon over them.
Put the flour, ground walnut, cinnamon and oat in a mixing bowl, then add the spread. Using your fingers, rub them together to make a breadcrumb texture. Add the sugar and combine.
Sprinkle the mixture over the figs evenly, then press the mixture down with the base of a spoon.
Bake in the oven for 20-25 minutes until golden.
Serve with vegan vanilla custard or ice-cream.
