I think maybe your daughters used one several years ago, from the way you worded your post? You might not be aware that 2 years ago they recalled the Easy Bakes that we knew and loved (or just wanted). Back then they were kinda fun, but the ones post-recall are just junk. The bulb was getting so hot that people were burning themselves on it, so now the bulb can't get hot enough to burn aka hot enough to "bake".
I think that even 3 years ago I would have a different answer (and I have a boy who would have loved one of them), and when we bought one for our nieces I was bummed that DS wasn't in the recommended age range yet, but then they were recalled and I saw what came out after, and was very very disappointed.
Yeah, I'm talking about like 10 years ago. Didn't know they were recalled. No more 100-watt bulb? That can't be! The bulb IS the Easy-Bake oven.
