You have to preheat the oven for a minimum of 15 minutes before attempting to bake anything, and it takes an additional 15 to 20 minutes to bake some wee cookies or an infinitesimal little cake. Light bulb technology at its finest! When your baked goods are cooked through, they sit on the cooling shelf for an additional 10 minutes. All for a cake the size of a biscuit. Plus, the mixes that come with the oven taste hideous, and refills cost upwards of $5 a throw.
All that being said, it's still interesting to mess with. For the DIY-minded, there are plenty of Easy-Bake recipes online, including tips on using regular store-bought mixes and recipes for homemade Easy-Bake treats like butterscotch, chocolate cake, and pizza. And um, wild mushroom flan, which is a recipe culled from The Easy-Bake Oven Gourmet. If only the book's recipe for roasted quail breast were online!
it would be funny to see how long it would take with a high efficiency light bulb :).
