Attempting to make Coconut Pringles - dough too crumbly

not a cook here. Attempting to make coconut based "pringles".

here's my recipe:

3/4 cup coconut blended into essentially coconut butter 3/4 cup coconut flour 1 tbsp arrowroot powder 1/4 tsp baking powder 1 cup water with 1/4 tsp salt

the idea was to run these through a pasta maker and cut out thin as possible circles that would crisp into pringly type chips. the dough is too crumbly. i'm assuming lack of starch? trying to make a coconut bacon type thing but in the shape of actual chips. http://ift.tt/174MthZ

any ideas on what i can do to make the dough less crumbly?
