Instructions
Heat oven to 200°C/400°Ff/Gas 6. Have a medium, ovenproof dish to hand.
Place all of the ingredients for the topping into a large mixing bowl, and rub all the ingredients together with your fingers to create a crumble texture. Shake the bowl to bring larger pieces to the top and rub in further if desired. Place the bowl in the fridge while you make the filling.
To make the filling, melt the butter in a pan over medium heat, then add the chunks of rhubarb and apple.
Add both sugars, cinnamon, and nutmeg and stir. Reduce heat to low and cook for 8-10 minutes until softened.
Pour the filling into the ovenproof dish and set it aside to cool for 5 minutes.
Sprinkle the topping over the now-cooled fruit filling and bake in the oven for 30 minutes or until golden brown on top.
Serve with custard, whipped cream, or vanilla ice cream for an extra treat!
Notes
Can be made in smaller dishes or ramekins for individual servings.
