Preheat oven to 170°C and butter and line a 20cm square baking tin.
Place chocolate, brew choc, butter, vanilla, cinnamon, paprika, cayenne and chilli flakes into the Thermomix bowl and melt 10 min/37°C/speed 1. Stop part way through to scrape down sides of bowl as needed.
Add cocoa, salt, sugar and eggs and blend 10 sec/speed 8.
Add pecans and combine 1 sec/speed 6.
Spread into prepared tin and bake 15 minutes or until the middle is just firm to the touch.
Allow to cool in the tin before removing.
These brownies will keep well in an airtight container out of the fridge.
