Preheat oven to 375 degress F. Line two baking sheets with parchment paper and set aside.
In a measuring cup, add 2/3 cup water and stir in 1/4 cup of chia seeds. Set aside for a few minutes to thicken.
In a mixing bowl, combine flour, sesame seeds, baking powder, and pinch of salt.
Add water and thickened chia seed mixture. Stir to thoroughly combine all ingredients.
Divide the dough in half between the two baking sheets.
Place a sheet of plastic wrap over the dough and flatten with hands a bit before rolling out. You'll want to roll it out to a thin consistency as they will rise a bit in oven; about 1/8 of an inch. Keep in mind that the thicker you roll your crackers the longer they will take to bake.
Place both baking sheets in oven and bake for 10 minutes. Remove from oven. Using a pizza cutter, cut your crackers into the desired shape and size. Place both baking sheets back into the oven for another 10 minutes.
Start to remove some of the crackers from the outer edges; these will harden first (before the center crackers).
Space out the remaining crackers, and put back into oven for another 8-10 minutes. You might need to let them bake another 5 minutes, after you've removed more crackers from the edges. Allow to cool completely in bowl or jar. Enjoy!
