Birthday ideas for my hamster?

Yeah I understand it sounds stupid, but my first hamster just turned 1 year old (approximately) and since hamsters don't have as many birthdays as other pets, I want to celebrate it. I was thinking about getting her a cool new toy and making a mini cake for her. I'm not sure out of what though. Im really into creative things so I was thinking about having a cute little party for her. Not where I invite people, but give her some time out of her cage and a few added treats and what not. I was just thinking maybe some of you guys had a few ideas.
