I usually add melted chocolate to my boxed chocolate cake mix (with milk & vanilla) but I've been reading  CC recipes and just tried the original WASC --awesome! I want to try the WASC chocolate cake extender but saw that it calls for cocoa powder.  I like a sweeter chocolate cake and am wondering if the cocoa powder might be not quite as sweet. Would there be a difference to the recipe if I sub melted chocolate?  Thanks!

The Chocolate WASC recipe I have calls for added sugar, chocolate pudding, and chocolate milk.  There's plenty of sweet in there, the cocoa powder doesn't take away from that.
 

Thank you!

I use chocolate fudge box cake mix, 4 eggs with yolks, 1/3 cup oil, 1/2 cup water, 1 cup sour cream, and 1 small pack of instant chocolate pudding. It comes out delicious every time! I've had tons of compliments on it.
