What would be a good invitation for a Candy and Cookies Sleepover?

Ok so for my birthday party I want to have a candy, cupcake, cookie sleepover. What that means is me and my friends will be split into three teams. Each team will start at a different table (Cookies, candy, or cupcakes). They must cook their dish as fast as possible and when it is in the oven they move to the next table. Then the next, then the next. And whichever team finishes all three stations first wins. And while our stuff is in the oven we will have normal sleepover fun like truth or dare, telling funny stories, watching tv, etc. But I wanted to know how I could do these invitations because I mean I can’t just say ’‘Your invited to a ’‘sweet’’ sleepover’’ because thats as cheesy as cheddar! So what should I do? Please include the whole message of the invite. In case you needed to know my name is Lexi and I’m turning 14. So you can put the whole message of the invite. And on your answer please include the whole message of the invitation, where I can make it for free online, some fun party activities, and just any cool ideas you have! Food, drinks, etc.! Oh and please tell me what can be a cool invite (like the background) background picture. Because if you can’t find it for free online it’s okay!Thanks so much!
