Chloe eats once a day too. She just won't eat more than that (unless it's like you said: goodies). Don't worry about it, as long as her stool is good and she is not losing weight, it's perfectly normal.
What you CAN do, is add a little warm water to her food, it will create a gravy like layer that will draw her to the food more.
