no, you don't have to add more water. But PLEASE add milk or even better, buttermilk instead of water. Buttermilk makes a big difference in this cake. I use it for RV cake mix all the time and it really is so much better!
Use the measurements on the box for the oil and instead of water, use the same amount of buttermilk. Add 1 extra egg (if it calls for 3 eggs, use 4), add 1 box instant chocolate pudding. I don't use butavan, I use vanilla, but whatever amount you normally use in a cake, use that.
"I use Duncan Hines Red Velvet and make it using 1 box of white chocolate (or milk chocolate) instant pudding mix, 4 large eggs, 1 c. buttermilk, 1/3 cup of oil. It gets rave reviews--very moist-- and it's a beautiful shade of red when cut."
This is instructions I received from blakescakes and it is very yummy. I prefer the white chocolate pudding. The milk chocolate makes it a little dark.
