Mix all and rest 30 mins.
Do stretch and fold.
On the second stretch and fold 30 mins later, add half the grahams, marshmallows and chocolate.
Do a 3rd and 4th stretch and fold.
Bulk ferment until almost doubled.
Preshape and rest 30 mins.
For final shape, lay dough in rectangle -scatter rest of inclusions as you shape and place into banneton.
Chill over night.
Preheat oven 425 - (I like to use dutch oven preheated instead of steel for sweet loaves) Keep a silver cookie sheet on bottom rack.
Place in oven and bake 30 min covered.
Uncover, lower to 400 and bake about 25-I pulled out at 195 degrees. Can tent it with foil the last 6 mins so it doesn't brown too much.
