Birthday ideas?

What's something special we can do for her first birthday? It's 4/1 so about a month and a half away. She gets pig ears and chicken feet pretty regularly so I want something even more exciting to make the day special. She's got 3 siblings so we can have a big party with just us lol. I was thinking about renting a huge field on SniffSpot so they can all play in a bigger area until they're exhausted.

Any really good dog cake recipes?
