1 cup corn syrup
1 cup granulated sugar
1/2 teaspoon salt
1 cup peanut butter
1 cup quick-cooking oats
2 cups corn flakes
2 cups Rice Krispies
1 cup semisweet chocolate chips
1/2 cup peanut butter chips (optional)

Combine corn syrup, sugar, and salt in a large saucepan and cook over medium heat until it begins to boil. (Or microwave on HIGH for 2 to 2 1/2 minutes until syrup bubbles form around the edge of the pan). Stir mixture until sugar dissolves. Stir in peanut butter and remove from heat.

Stir in oats, corn flakes, Rice Krispies (or substitute 5 to 6 cups of your favorite cereal). Pour mixture into greased 8-inch square pan and set aside.

Melt chocolate chips in small saucepan over lowest heat, stirring constantly. (Or microwave on MEDIUM-HIGH (70%) for 1 minute. Stir, then microwave at additional 10 to 20 second intervals, stirring until smooth). Spread over bars. If desired, melt peanut butter chips and use small spoon to dot or drizzle onto bars in any design you prefer. Cut into squares or triangles.
