We'll say that again, only 4 ingredients! We've raised the game a little by adding a chopped peanut chocolate shell and a salted caramel core.
Start by melting dark chocolate and coating the inside of 4 plastic cups.
Sprinkle chopped peanuts over the setting chocolate then place in the fridge to set.
Blend 6 banana then add the melted dark chocolate (saving some for later to seal the tops of the cups), then divide between the chocolate cups.
Pipe salted caramel into the centers.
Seal the tops with the remaining melted chocolate and stick in the wooden sticks.
Set in the fridge.
