A:Answer Hi SuzieQ - Thanks for considering Café Model CGS750P4MW2! This range has a traditional upper oven and a convection lower oven, therefore you will need to use the lower oven for cooking pies and cookies with convection technology. Also, the ovens cannot be joined together to create one cavity. The upper oven can be used for single rack baking of cookies, cakes, muffins, breads, biscuits, casseroles, pizza, chicken nuggets, potato products, appetizers, etc. We suggest viewing the Cooking Guide on page 19 of the Use and Care Guide for suggestions: https://products.cafeappliances.com/MarketingObjectRetrieval/Dispatcher?RequestType=PDF&Name=49-2000202-2.pdf - Explore our Café Customizable Matte White Professional Collection at: https://www.cafeappliances.com/collections/customizable-professional - We'd love to have you in the family.
