Loaf falls apart in the middle

Toast

Hi, I'm making my loaves in a tin. The centre of the loaf just falls apart. The outer portions hold together. It seems baked through. After taking it of the tin I put a tea towel over it to give a softer crust. Any ideas?

Also could have been underbaked  and inner part was not cooked to done-ness. Can happen with too hot of an oven and not baking long enough, so outer crust looks done, while inside is still too wet.

 Could also be too wet of a dough.

Do you have a probe thermometer to take inside temp?  That's what I use to tell if the inside is done.  There is also the "thump-test."

Looks nice!
