Add the flour, and baking powder and stir until combined
Fold in the chocolate chunks (save some for topping if you like)
Pour into a loaf pan lined with parchment paper (and add the rest of the chocolate chunks on top). The pan I used is about 12cm x 20 cm / 5 inches x 7,5 inches
Bake at 180 Celsius degrees (350 in Fahrenheit) for 30 - 40 minutes
