Preheat the oven to 350 degrees F. Lightly grease a 9- by 13-inch cookie sheet.
In a bowl, mix all the dry ingredients together. Add the wet ingredients to the dry ingredient mixture. Spread the mixture thinly and evenly on the prepared cookie sheet. Bake until golden brown, 8 to 10 minutes. Let cool. Break into shards. Use as garnish for Pumpkin Milk Shakes.
