Servings: 12


  • 1/2 cup peanut butter (130 grams)
  • 1/4 cup sugar (50 grams)
  • 1/4 cup corn syrup (70 grams)
  • 1/4 teaspoon vanilla extract
  • 3/4 to 1 cup crushed Cornflakes measure after crushing (45/70 grams)**
  • 4 oz milk chocolate Lindt or Cadbury


  • Line inside of a 9x5 inch loaf pan with nonstick foil.
  • Put the peanut butter, sugar and corn syrup in a large saucepan. Set over medium heat and stir just until sugar starts to dissolve and mixture is smooth and shiny. Do not bring to a full boil. The goal is just to soften and melt.
  • Add the vanilla and the crushed cereal and stir well, then spread mixture in the loaf pan. Press down flat.
  • Melt the chocolate in either a double boiler or the microwave. My favorite method is to use the microwave at 50% power and stir every 30 seconds. Pour melted chocolate over bars. Chill until set.
  • Lift bars from pan and cut into small squares.


To get 1 cup of crushed Cornflakes, you'll need to start out with a little over over 2 cups uncrushed.
