Hey Kylie!
Would having a single cupcake set you off? Or is the thought of having to buy (or make) the dozen or so that you think might lead to a binge? There's always the option of doing a single-serving microwave cupcake! I love Hungry Girl and she posts recipes like that all the time!
Here is one for a Peaches and Cream cupcake:

You'll get one cupcake and that might help with the craving.
If you think just one will set you off though, I'm not sure what advice I can give for that, since I struggle with it too!
Good luck! You can make it through this!
