In a food processor, grind chocolate into tiny pieces. If you are using a chocolate bar, you can use a grater. Set aside.
In a mixing bowl, combine eggs with honey. Blend them together, until they turn into a foamy mixture and triple in volume.
In a separate bowl, combine together flour, baking soda and cacao; set aside.
Fold in oil, chocolate into the egg mixture, stir until combined.
In small portions, fold in flour mixture into the eggs. Mix until ingredients are well combined together.
Divide dough into eight equal pieces or you can weigh each piece individually. This way they will all turn out the same size.
Here is the trick to rolling it out easy. Flour surface generously; this will help you work with the dough easier, since the dough is sticky. To move it onto the baking sheet, roll it up onto the roller, and unroll it onto the baking sheet. Make sure it measures out to be large enough to fit the shape you will cut out later.
Bake at 350F for 5-7 minutes, until browned. During the process of baking, roll out another layer to speed up the process. When it's done, remove it from the oven and cut out each circle by placing a plate over the top. The key trick to making all of the sides perfect, is to cut the cake right after baking. You'll need the excess pieces (sides you have left over) to use for later decoration.
