Prepared cake mixes from the supermarket contain the same ingredients Easy-Bake Oven mixes do -- sugar, dried egg whites, flour and nonfat dry milk -- so you can use them interchangeably. The Easy-Bake Oven reaches about 350 degrees Fahrenheit in 10 minutes, and it has no problem baking regular mixes if you pour the batter into the provided pans or pans of a comparable size. Always supervise children when they use the oven; Hasbro, the manufacturer, recommends it for children 8 and older.

Check the cake or muffins for doneness after 30 minutes.

Batter Consistency and Height

Mix the batter according to the box's instructions and fill the pan no more than three-quarters full; regular mixes produce a little more rise than Easy-Bake mixes. You can use alternative pans, such as miniature loaf pans and miniature round tins, as long as they clear the heating element by 1/2 inch.
