Mix sugar, honey and peanut butter in large microwavable bowl. Microwave on high for 1 1/2 to 2 minutes or until bubbly at edge; stir until well blended. Stir in cereal and raisins. Press firmly into 8-in square pan sprayed with cooking spray. Cool. Cut into bars. Store in air-tight container.
Alternatively, you can cook the bars on the stove. Mix sugar, honey and peanut butter in large saucepan; cook on medium heat until smooth and bubbly, stirring occasionally. Continue as directed. After completely cooled, wrap bars individually in plastic wrap.
