Do you have an oven thermometer? If you set your oven to 350 - is it really 350 during the baking process? All ovens should be calibrated - especially as they age or get constant use.
When your oven temperature is too low the structure of your cake may not set as it should - even though you cooked your cake the proper amount of time.
Do you test your cake with a wooden toothpick?? Insert in the middle and if there is any "batter" on the toothpick - your cake is not done and needs to cook longer.
Cakes do not always cook in the same amount of time.
When making a cake, playing around with the sugar and fat in the recipe to save on calories will do it too. Old baking powder does that too - but this is for homemade cake recipes.
Most likely - I would say it's your actual oven temperature versus what your oven dial is set to. A cheapo oven thermometer will help you to get your oven to the right temp before you put your cake in to bake.
