Instructions

Mars bar rice krispie layer

  1. Line an 8 or 9 inch square pan with parchment paper.
  2. Cut the mars bars into pieces (1 - 2 inch pieces are fine), and place them in a large saucepan (enough to fit 3 ½ cups of rice krispies).
  3. Add the butter and salt (only if using unsalted butter).
  4. Heat the candy bars, butter, and salt mix over medium heat while stirring until everything is dissolved and the mix is smooth. Make sure the mix doesn't burn at the bottom of the pot.
  5. Once the mixture is melted and smooth, turn off the heat, and add the rice krispies.
  6. Quickly mix in the rice krispies until it’s all evenly coated.
  7. Remove the pot from the stove, and scrape the rice krispie mix into the prepared pan. Using a spatula, press the mixture into the pan to get an even layer.
  8. Set aside until you prepare the chocolate layer.

Chocolate layer

  1. Place the chocolate, salt, and coconut oil in a microwave-safe bowl. Heat in the microwave in 20 - 30 second bursts, while stirring in between, until the chocolate is about 80% melted.
  2. Continue to stir the mix until all the chocolate is melted. The chocolate mix is now ready.

Assembly and cutting the Mars bar slice

  1. Pour the chocolate topping over the rice krispie layer. Use an offset spatula to evenly spread the chocolate layer.
  2. Let the two layers set. You can transfer this to the fridge to let it chill faster.
  3. When the mars bar slice is set, remove it from the pan. If the slice is very cold, let it soften to room temperature a little, as it will be easier to cut then.
  4. Using a sharp knife, cut into portions. I prefer to cut the slice into 16 portions (about 2 x 2 inches per piece). But feel free to cut them into any size you like.

Storage

  1. Store these slices in an airtight container. Place parchment paper or wax paper between layers to prevent sticking.
  2. These will keep in the fridge for at least 2 weeks, and up to 6 months in the freezer.
  3. Allow the slices to come to room temperature before eating, for the best flavor and texture.

Notes

  • Store them in an air tight container in the fridge for upto 2 weeks. However, let them rest at room temeprature before eating. This helps to soften the rice krispie layer. 
  • They can also be stored in the freezer for up to 6 months. But let them fully thaw out before eating.
