This is totally from Carol from the family cookbook, but I had it on my blog and wanted to link it to the recipe here, so here it is:
1 cup sugar
1 cup corn syrup
1 cup peanut butter
8 cups corn flakes
Bring sugar and corn syrup just to boil on medium heat. Remove from heat, stir in peanut butter well. Add to corn flakes and mix well then put in buttered 9x13 pan. Eat by the handful or cut into squares.
