Preheat oven to 160 degrees celsius (fan-forced).
Grease and line a 20cm square cake tin with baking paper, allowing the edges to overhang.
In a large bowl, whisk together the plain flour, rolled oats, salt and bi-carbonate of soda. Stir in the raw sugar and brown sugar and mix until smooth.
Add the vanilla extract and melted butter to the dry ingredients.
Stir mixture until well combined.
If using a Thermomix: Melt the butter and vanilla extract for 3 minutes, Speed 2, 80 degrees. Add the plain flour, rolled oats, salt, bi-carbonate of soda, brown sugar and raw sugar. Mix for 20 seconds on Reverse, Speed 2. Scrape down the sides. Mix for a further 20 seconds on Reverse, Speed 2.
Press just over half of the crumble mixture into the base of the prepared tin and use the back of a spoon to smooth the mixture into an even layer.
Bake in the preheated oven for 15 minutes, until golden.
Remove from oven and set aside to cool slightly (leave the oven turned on).
Spread the Nutella over the top of the cooked base. Use ½ cup Nutella for a thin layer or ¾ cup for a slightly thicker layer (the more the better in my opinion!).
Sprinkle the remaining crumble mixture over the top of the Nutella.
Bake in the oven for 20 - 25 minutes or until lightly golden.
Remove from oven and allow to cool.
Cover and refrigerate for at least 2 hours (preferably overnight) then take it out and cut into squares.

RECIPE NOTES & TIPS:

All ovens are different - the slice is ready when the crumble is golden. I specify degrees celsius (fan-forced) for my recipes. If you're using a conventional oven, increase the temperature by 10-20 degrees celsius.
Allow the base to cool slightly before adding the Nutella (this will make it easier to spread).
If you find that your crumble is over-browning, simply add a sheet of foil loosely over the top and continue baking.
This crumble slice is delicious served cool or warmed up with a scoop of ice-cream, custard or cream.
Cut the slice using a sharp serrated knife.
Store the slice in an airtight container in the fridge for up to one week.
Freeze the slice in an airtight container for up to 3 months. Allow to defrost in the fridge before consuming.
