A family recipe...
2/3 C. white Karo syrup
1 C. Brown Sugar
1 C. Peanut Butter
5 C. Cocoa Pebbles
Bring syrup and brown sugar JUST to a boil, stirring constantly. Do not use high heat. Take pot off stove immediately and stir in the peanut butter thoroughly, then stir in the cereal. Spread in a 9x13 or 9x9 lined with waxed paper. Press down. Cut when cool.
You'll definitely want to prep your ingredients ahead since you're working with heated sugar!
You'll never go back to Rice Krispie Treats again!
