Melt the chocolate and butter slowly over low-medium heat, stirring frequently- be careful you do not want to burn the chocolate.

Step 5

Pour into prepared pan and bake for 28-33 minutes, until the edges are set and the center jiggles only slightly when the cake  is shaken gently.


Step 6

Cool for 30 minutes on a wire rack then I like to place the cake in the fridge for another 30 minutes to an hour to set up. If you don't it  will be very, very soft.
