It probably just slid through - and yeah that sucks to kind of "wake up" and realize that... Some old habits are so tenacious!!!
I bet the toasty crispy bit reminded your brain to chew thoroughly - more so than with plain bread - and that made it easier to go through.
Breathe, forgive yourself (but don't forget), and face tomorrow. Calorically it's not the end of the world... And you know the rest.
