1/2 c. brown sugar
1/3 c. light corn syrup
1/4 c. butter
2/3 c. peanut butter (I used chunky)
1/2 tsp. ground cinnamon
4 c. Total cereal
2/3 c. raisins if desired

Butter square pan 9 x 9 x 2. Heat brown sugar, corn syrup, and butter in a 3-quart saucepan over medium heat, stirring frequently until sugar is melted and mixture is smooth. Remove from heat; stir in peanut butter and cinnamon until smooth.

Mix in cereal and raisins until well coated. Press mixture into pan evenly and firmly; refrigerate at least 2 hours. Cut into bars.
