For the Base:

  • 1 cup unsalted butter melted and slightly cooled (210g)
  • 1 cup creamy peanut butter (300g)
  • 1 ¾ cups powdered sugar (210g)
  • 2 cups graham cracker crumbs (240g)

For the chocolate topping:

  • 1 ½ cups semi-sweet chocolate chips or milk chocolate chips (280g)
  • 1/4 cup creamy peanut butter (65g)


  • Line a 8x8 or 9x9 dish with parchment paper or foil.
  • Crush graham crackers in a ziploc bag using a rolling pin or blitz using a food processor.
  • Melt butter in a large bowl add peanut butter and mix until smooth.
  • Beat in powdered sugar then fold in the crumbs. Transfer to lined dish and smooth.
  • Melt chocolate and peanut butter, pour over the peanut butter base, smooth then chill for at least 90 minutes.
  • Cut into bars and enjoy.



  • You'll need to use an 8x8 or 9x9 square dish for nice thick bars.
  • Make sure to line your baking pan or square dish with parchment paper so you can easily remove the bars after chilling.
  • Make sure to use creamy peanut butter such as Jif or Skippy. Oily peanut butter may stop the base from setting and will change the texture.
  • Use a hand whisk to incorporate the butter and peanut butter so you avoid any lumps.
  • You can use the stovetop or microwave to melt the chocolate. If using a stovetop do this in a bowl over a pot of simmering water.
  • The peanut butter gives the chocolate a creamier texture once set. This really helps when cutting the bars so the chocolate doesn't crack.
  • Make sure to let the bars chill in the fridge for at least 90 minutes before serving. Alternatively, you can make them the night before and let them chill overnight.
  • To cut the bars use a sharp or serrated knife.
  • Will keep well in the fridge for 5-7 days or can be frozen.
