In a greased 13-in. x 9-in. baking pan, combine the oats, walnuts and coconut; set aside. In a small saucepan over medium heat, combine syrups and cinnamon; bring to a boil. Cook and stir for 1 minute. Remove from the heat; stir in vanilla. Pour over oat mixture and toss to coat. Bake at 275 degrees for 30-40 minutes or until golden brown, stirring every 10 minutes. Cool, stirring occasionally. Store in an airtight container. Yield: about 2 cups.
