Step 1 - Crush The Tim Tams
Place the Tim Tams into the Thermomix bowl and crush (you can crush them as finely or chunky as you like!).
Personally, I find 2 seconds is a good amount of time.

Step 2 - Mix
Add the self raising flour, brown sugar, cocoa powder, coconut and sweetened condensed milk and mix together on REVERSE.

Scrape down the sides of the bowl and mix again using the REVERSE function.

Step 3 - Bake
Spoon the mixture into a prepared baking tin. Smooth the mixture out with the back of a spoon.
Bake for 20 minutes or until a skewer inserted into the middle comes out clean (or with a few crumbs on it).
Allow to cool before cutting into pieces.
