Special K Bars

1 c sugar
1 c Karo syrup
4 tbls butter
1 1/2 c peanut butter (creamy is best)
6 c Special K cereal
1 c chocolate chips
1 c butterscotch chips

Boil the first three ingredients for one minute; add the peanut butter and stir until creamy and well mixed. Pour over the cereal and mix thoroughly. Spread into a 9X13 pan for thick bars or a cookie sheet (with sides) for thinner bars. Melt the chips together and spread over the smooth cereal mixture. Cool and cut.

Notes: Using the store-brand equivalent cereal is fine. In fact, I prefer it because it's lots cheaper and we get to make fun of the silly name.
I butter the back of a spoon and use it to firmly press the mixture into the pan.
I also sprayed the pan with non-stick spray.
These bars mail very well and stay fresh a long time. (perfect for mailing)
