I don't know if this is dark enough, but it is by far the best chocolate scratch cake I have ever had...it always tastes better with each day that passes..(gets more and more moist it seems). They have a dark recipe too, but I think all they change is the cocoa to dark cocoa. The frosting is very tasty too.
