My Duncan Hines white cake mix usually ends up sinking in the middle and doesn't rise all the way to the top and the cake isn't usually cooked consistently throughout...any ideas on how I can doctor the cake mix to make it work?

I use 1/2 of a WASC recipe for the wondermold...so it would be:

1 DH white cake mix
1 c flour
1 c sugar
1 1/3 c water
1 c sour cream
4 egg whites
1 tbsp oil
2 tsp clear vanilla

And bake at 325. It makes a fairly dense cake in the wondermold, but everyone loves it.

Are you putting the metal rod through the middle? That is what helps it to cook evenly. Also I bake at 325 instead of 350.

I have made tons of different flavors in the wondermold pan, including marble. I do use doctored mixes, so try looking up the cake extender in the recipes section and add that to your mix.

I use KakeLadi's original Wasc recipe ... works great for me.

Yep, I use the rod in the middle. Not sure why it sinks though...Most like the mix. I haven't tried Betty Crocker yet, but might try that too.

I've wanted to try to wasc recipe as well..thanks!!
