I used a Betty Crocker recipe to make mine. It was suggested to use an 8x8 or 9x9 square pan. I didn't have either, so I used a 7x11 pan from the QVC network called "temptations". I followed the recipe to bake at 350 for 25-30 minutes after baking the crust. The filling turned a dark brown after baking. What did I do wrong?
