Where did my muffins go wrong?

[Guest guest]

I just tried the basic muffin recipe and my muffins flopped. I used freshly

ground and soaked soft white wheat flour and followed the recipe exactly. I

baked in a pampered chef stoneware muffin pan in a convection oven. The recipe

called for 325 for an hour; the stoneware and my convection oven instructions

advise to lower the temperature by about 25 degrees and cooking time as

necessary. I baked at 300 degrees for an hour, and they still weren't done in

the center; and then I baked for 20 more minutes at 325. They still weren't

cooked. I would appreciate any advice. Thanks
