This blackberry and apple crumble combines tart apples and juicy blackberries beneath a buttery crumble topping. The Thermomix takes care of the crumble topping in seconds so there's no need to rub butter into flour with your fingertips.
Serve warm with custard, cream or a scoop of vanilla ice cream.

Once you've made this, my Thermomix rhubarb crumble is another winter warmer and a great one to try.
Why You'll Love This Recipe
- A classic English pudding which never gets old.
- Ready in under an hour.
- Uses frozen blackberries, so you can make it all year round.
Recipe Ingredients

Note: The full quantities are shown in the recipe card below.
- Apples - Granny Smith apples are the perfect choice - they're tart and hold their shape well during baking. Other apples will work but may go mushy. Cut into even 2cm cubes so they cook through evenly.
- Blackberries - I always use frozen as they're cheaper and available year-round. No need to thaw, just add them straight to the baking dish.
- Plain flour - plain flour gives you that classic crumbly topping. If self-raising is all you have, it will still work but the topping will be more biscuity in texture.
- Unsalted butter - must be straight from the fridge. Cold butter is what creates the crumbly texture; soft butter will turn the topping into pastry.
- Brown sugar - used in the crumble topping for a hint of caramel flavour.
- White sugar - just a small amount in the filling to balance the tartness of the fruit.
- Cinnamon - adds a hint of spice.
Step-by-Step Directions
Note: This is a summary of the instructions. The full ingredients and instructions are shown in the recipe card below.

- Add the blackberries, apple pieces, white sugar and cinnamon to your baking dish and toss to combine.

- Add the flour, chilled butter and brown sugar to the Thermomix bowl.

- Mix until the mixture resembles coarse crumbs and starts to clump together.

- Tip the crumble topping evenly over the blackberries and apples and press down gently with the back of a fork. Bake in the oven for 35-40 minutes until golden brown and the blackberries and apples are bubbling around the edges.
Recipe Tips
- Don't be afraid to pile the crumble topping high - the fruit will shrink down as it cooks.
- You can also make individual portions in ramekins - just reduce the baking time and keep an eye on them.
- My favourite way of serving this is with Bird's custard for a proper British finish. You can find it at speciality stores in Australia.
