Yea, I'd avoid those ingredients. Here's my take on bunny cookies:
When we make cookies for people, it's important to have a good exact recipe because you're essentially making a chemistry project working with water, flour, baking soda/powder, eggs etc...you don't want your cookies to turn out too lumpy, too hard, to flour-y, etc. Also, specific heat requirements are needed to sterilize the "dangerous" raw ingredients like eggs (who am I kidding, raw cookie dough is delicious haha). However, the great thing about most bunnies is that they don't care about these requirements! I never use a recipe when I make bunny cookies, and in fact I'm pretty sure they've been different every time just depending on what's in my fridge. But they're always well received.
Just start with some softened pellets (add a bit of water to pellets and they'll come apart easily with a bit of poking) - this will be your "flour". As far as the rest of it goes, add however much juice/diced fruit/veggies/bunny-safe tidbits as you want. If it's too dry, add more juice/water; if it's too wet, add more "flour". Simple as that!
Mix into a homogenous "dough" and shape however you see fit - either in sheets, or if you're less lazy than I am, in individual treat-sized balls. As for baking time, the goal is to dehydrate out the cookies so that they keep well...unlike human cookies, an exact temperature and time aren't necessary to make your chemistry turn out perfectly. I usually turn the oven to 200-250 and bake for as long as it takes for things to become nice and crispy without burning them. This usually takes quite a while and makes my entire apartment smell like a strange mixture of pellets and fruit.
As you can tell, I'm the kind of person who just eyeballs everything when I cook haha. But really, it's fun! No need for recipes or measuring; just play with different bunny-safe fruits and veggies! Chances are Cinnabun will love whatever you make .
