I do. Now while on an "ideal diet" you'd never have this, I'm not on a diet, I'm in a lifestyle change. So yeah, sometimes I get to eat stuff that I shouldn't.
Low fat milk: 225ml 92 calories
Chocolate powder: 8.5gr 34 calories
Mini Marshmallows: (based on weight) 25 calories
Total: 151calories of yummy
Actually, this is just a "cheap" version of something I really, really love...
I prefer my version because I can increase or decrease the caloric value as I see fit or to be within a daily limit (add water instead of milk, or 50/50), I can add less cocoa, no marshmallows. That and it's cheaper. Either way, it's a good way to end the day when you've got a few calories to spend and feel like a semi-guilty snack.
