I messed up my first batch by adding pudding to it so now I dont have chocolate cake mix....i have a white cake mix, can I make that chocolate? How?

Yes, if you have cocoa powder or chocolate syrup, even chocolate that you can melt (bakers chocolate). What I usually do is check recipes for scratch chocolate cake and see how much they add to it and then you can use the same amount to your cake mix.

hi, there is a recipe in the recipe section here, that tells this. hth
