Heat oven to 300*F.

In a food processor or blender, add oats and process into fine flour.

Add corn starch, flour, brown sugar, baking powder and salt. Process until well blended and mixture is very smooth.

In a medium bowl, add water one teaspoon at a time using just enough water until dough forms (about 3 tablespoons total).

Knead dough a few times and form into a circle.

Cut dough into 8 equal sections, and cover with a wet paper towel to keep dough from drying out while you work.

On a lightly floured surface, working with one section at a time pinch out into a long, thin, round snake, about a foot long.

Using a sharp knife, cut into thin slices, about 1/4-inch thick.

Use a skewer, make a hole in the center of the dough piece and reshape into a circle.

Place in a single layer on ungreased baking pan and bake 25 to 30 minutes, stirring every 5 minutes or until dry and lightly browned.

Cool completely, about 20 to 30 minutes.

Store at room temperature in an air-tight container.
