Fair trade chocolate bars are made from cocoa beans which are bought for a fair price from farmers.
Cocoa farmers
Cocoa farmers are some of the poorest people in the world and many of them earn on average about £50 a year.
They depend on selling their beans to pay for the essential things in life including wellington boots to protect their feet from the scorpions that live among the cocoa trees.
However many farmers don't make enough money from selling their beans and can't afford food, medicine, clean water or school for their children.
Working together
In 1993, a small group of cocoa framers in Ghana, West Africa realised that by working together they could get more money from the people who bought their cocoa.
They pooled their resources and set up their own business called Kuapa Kokoo which means "good cocoa farmer" in their local language of Twi.
Divine
In 1998, Kuapa Kokoo joined forces with a group of UK organisations who care about getting cocoa farmers a better deal.
They formed The Day Chocolate Company and started making their own bar - Divine.
For the first time, Kuapa Kokoo began to make money from selling chocolate as well as from growing cocoa beans.
The farmers own a third of the company's shares which means they also have a say in how the chocolate is produced and sold.
Dubble
In January 2000, Comic Relief teamed up with Kuapa Kokoo and The Day Chocolate Company to create a chocolate bar for young people called Dubble.
The wrapper was designed by an 11-year-old girl called Gracie from Exeter who beat 16,203 other competition entrants.
