Pre-heat the oven to 170°C.
In a saucepan, bring 10 cl of CHOUFFE Soleil to the boil.
Gradually add the cocoa powder and the rest of the beer. Stir over a low heat until the liquid has a nice consistency.
Remove the mixture from the heat and let it cool.
Meanwhile, beat the eggs and sugar until they become white.
Add the melted butter and the beer-cocoa mixture.
Then add the flour, dark chocolate (cut into small pieces), baking powder and some lime zest.
Mix until you obtain a nice consistency.
Pour the mixture into the buttered muffin cups.
Bake for 40-45 minutes in the oven, according to taste.
Let them cool and enjoy!
