Here's a link to Zwieback Toast on wholesomebabyfood.com I didn't want to infringe on any copyrights so I didn't copy the recipe.
This recipe is based on one from wholesomebabyfood.com I made some tweaks therefore I believe it is violation free :) I haven't made them yet so if you do please let me know how they turn out!
Teething Biscuit Recipes - Eggless Baby Cereal Cookies
Ingredients:1 cup flour 1 cup dry infant rice cereal
1 cube thawed(not warm though) any flavor puree (about an 1-2 oz. please see my recipe page for info on making purees for your baby)
1 teaspoon cinnamon or nutmeg (or both)
3 tablespoons cooking oil
Preheat oven 425F
Mix flour and cereal.
Gradually stir in oil and puree. Start mixing in cold water a little at a time, starting with about 1/4 cup until dough begins to form a ball and pull away from the bowl.
Put dough into a piping bag or zip top baggy with a snipped corner and pipe into small bars, rounds, hearts, letters or whatever you like on an ungreased cookie sheet.
Bake 10-12 min. or until lightly brown. Cool completely.
Store in an airtight container. You could use flavored baby cereal and omit the puree if you choose. You could also leave it unflavored as well!
