I have have had three cakes sink on me in the last few weeks 2 were done with round 3 inch deep pans and 1 with a collared oval pan. I did nothing different. just doctored my D H mixes as usual and my 11 x 15 cakes were perfect so I doubt it is my oven.. It has been horribly hot and humid but I have my air running. I am at a loss to figure it out the problem.

Can't help except to tell you that you are not alone. The same thing happened to me a few months back. Only mine was pillsbury. 3 whole cakes ruined. I gave up, and the next time I baked one, everything was fine and has been ever since! It's a mystery!

For awhile several people had problems with DH mixes. No one could figure out why.

Did you make sure your cakes were cool enough to pick up before moving them? I've had my cakes fall apart when I didn't wait long enough.

I had the same thing happen to me the other day with a DH dark chocolate fudge cake. But I doctored it differently and think that was my issue.
I redid it with just an extra egg and box of pudding and it turned out perfect.

I feel your pain!!! I find the the cake companies constantly change their mixtures to make them more moist. I have called them and they have suggestions to change the directions to make the cake sturdier for a wedding cake. It is very frustrating, expecially when you make a 16" and put all the time and money into it to find that they changed the ingredients again!! Why can't they leave everything alone????????

Did you recently get the 3" pans? l did, and had every cake fail for a while! Whether it was a mix or scratch cake it came at sunken in the center or with a gooey mess despite using a heating core. l finally started using only 1" of batter in the pan and doing separate layers rather than torting. The exact same recipe i had used previously, that had sunk, came out perfect with this. l guess the moral of my tale is to stick to the 2" pans! l hope this helps-l learned the hard way. I must have ruined at least six cakes. Have not had another problem since, and l use DH too.
