Heat oven to 190C/170C fan/gas 5. Mix the crumbs, chocolate and sugar. Melt the butter with the maple syrup, then stir into the dry ingredients.

Put the chopped pears in a 1-litre shallow ovenproof dish. Spoon over the chocolate mixture, then roughly spread to cover the pears. Bake for 25-30 mins. Cool for 10 mins, then serve on its own or with vanilla ice cream or yogurt.
