Notes from Rouba

  • Dice Mars Bars into small pieces for easier melting.
  • Stir the Mars Bar mixture occasionally while melting to ensure smoothness.
  • Press the mixture firmly into the tin for a compact and well-formed slice.
  • Allow the slice to set in the fridge for a minimum of two hours to ensure firmness.


Step 1.

Dice the Mars Bars into small pieces. In a saucepan, melt the butter and Mars Bars slowly over low heat, stirring occasionally until melted. It may look a little lumpy, but that’s okay. 

Remove the saucepan from heat and pour the melted Mars Bar mixture over the rice bubbles in a mixing bowl. Stir gently until the rice bubbles are evenly coated. 

Step 2.

Line a baking tin with baking paper and pour the Mars Bar and rice bubble mixture into the tin. Press it down firmly with the back of a spoon or with your hands.

Place the tin in the fridge and let it set for at least a couple of hours, or until firm.

Step 3.

Once the Mars Bar Slice has set, carefully lift it out of the tin using the baking paper and place it on a serving plate.

Melt the milk chocolate in a microwave and then drizzle it over the top of the Mars Bar Slice for an extra chocolatey touch.

Garnish with pistachios
