Place peanuts and nibs into a cold oven set to 200°C and roast 10 minutes exactly.
Place all ingredients, while the nuts and cacao nibs are still hot, into the Thermomix bowl and blend 1 min/speed 8. Scrape down sides of bowl and lid.
Blend a further 2 min/speed 6.
Pour into a lined loaf tin and freeze until solid. Cut and wrap individually. Store in the freezer or fridge until use.
These will melt quite quickly in the first few hours after being frozen, but then they should settle. I think they will go soft pretty fast though, so should remain chilled up until eating them.
