2tablespoonsof oats, to sprinkle on top (optional)
Instructions
Preheat the oven to 200°C/400°F (180°C fan)
For the Blackberry & Apple Filling
Peel and core the apples and roughly cut them into 2cm cubes. Place them in a medium-sized baking dish (mine measured 16cm x 23cm), then add the blackberries, sugar, and cinnamon. Toss to combine.
For the Crumble Topping
Weigh the flour, butter and sugar into the Thermomix bowl and mix for 15-25 sec/speed 5. (It should look like sand, but be careful not to overmix, or it will become pastry!)
To Assemble
Tip the crumble topping evenly over the blackberry & apple filling and press down gently with the back of a fork. Scatter over the oats.
Bake in the oven for 40-45 minutes until golden brown and the blackberries and apples are bubbling from the sides.
Serve immediately with piping hot custard or a scoop of vanilla ice cream.
Notes
Storage: The crumble can be stored (covered) in the fridge for up to three days.
