What is a food thats hard on the outside with a runny outerlayer?

I need to find a food that represents a character in my book. I want to do a food that is hard or tough on the outside, but when you bite into it, the inside all comes runnning or spilling out. It can be any type of food. Just not candy.|||I'm thinking cream filled chocolate 茅clairs.|||An egg - Raw


An egg - cooked over easy has somewhat of the same effect


Suckers with tootsie rolls or bubble gum in the middle


Mozzarealla Sticks


Jalapeno Poppers


Stuffed Peppers


Hard Shell Tacos


Twinkies


An ice cream cone with that hardening shell on it?


Gushers


Filled doughnuts





Good luck!|||Cadbury eggs
