1. Line a baking sheet with parchment paper; lightly coat with cooking spray.
2. Combine sugar, corn syrup, and 1/2 cup water in a medium heavy saucepan over medium-high heat, stirring just until combined; bring to a boil. Cook, without stirring, until a candy thermometer reaches 335°. Remove from heat; stir in cashews and remaining ingredients (mixture will bubble). Quickly pour mixture onto prepared pan, spreading evenly. Cool completely (about 2 hours); break into pieces.
