This is a base recipe.
Do what you want with it, change things up. But IMO the eggs are important. So its not vegan or anything. But on the other hand are there any egg substitutes that could work?
Overnight Teething Biscuits
1 c brown or white sugar ( I know thats a lot, use any sugar substitute, but NOT honey! )
2-2 1/4 C Flour ( I use part white, part whole grain graham flour)
1/4 C wheat germ
dash of cinnamon
Break eggs into bowl and stir til creamy.
Add sugar, and continue to stir. Gradually add enough flour to make a stiff dough.
Roll out between two sheets of wax or parchment paper, to about 3/4" thickness.
Cut into strips or rounds or whatever you want.
Place on lightly greased cookie sheet.
Let stand over night (10-12 hrs)
Bake at 325F until browned and hard.
This will make about 12 durable and almost crumb free teething biscuits.
I got this recipe from one of these forums over the years can't remember where though.
