1. In large pot, combine Karo Syrup and sugar. Bring to a slight boil. 2. Stir in the peanut butter until smooth. 3. Remove from heat and add Rice Krispies a little at a time to get the right mix…Not too much or little! 4. Put mixture in a greased and foiled 9 X 11 pan. Set Aside... 5. Place both packages of morsels in a double broiler or microwave safe bowl. For stove top, heat on low, stirring occasionally until melted. For microwave melting, heat for 1 minute, stir, then heat in 30 second increments until melted, stirring between. 6. Spread the morsel mixture on top of the Rice Krispie mixture. Allow to cool completely. (It usually takes 6-8 hours before you can cut.) 7. To cut the bars, I find it easiest to flip the pan over onto a cutting board.
