Preheat oven to 325F. Coat a 15x10 inch baking pan with cooking spray.
In a food processor combine next 5 ingredients (through flour). Cover and process until finely ground. Add next 6 ingredients (through coconut extract). Cover and process until combined. Transfer to a large bowl. Stir in chia seeds (mixture will be crumbly).
Using the bottom of a measuring cup, press oat mixture firmly into prepared baking pan. Bake 18-20 minutes, or until golden. Cool in a pan on a wire rack (mixture will crisp as it cools).
Using a table knife or small metal spatula, release oat mixture from pan. Break into small bite-size pieces. Store at room temperature up to 1 week. If desired, serve with milk and fruit.
