Preheat Oven to 350 degrees.
Lightly grease a large cookie sheet with unsalted butter and some rice flour.
Combine all ingredients in a large bowl and mix well. If needed, add a couple tablespoons of water. The dough should just come together and not crumble.
Roll the dough out on a floured surface; make sure the dough is of consistent thickness.
Using a knife or cookie cutter or sharp knife, cut dough into desired sizes and shapes. Place cookies on cookie sheet. Bake for about 15 minutes, until golden brown.
Let cool for a couple of hours. Cookies will get harder the longer they cool. Store in an airtight container or in the freezer for up to two months.
