Mars Bar Squares

  • Total Time

    15m
  • Serves

    16


The humble Mars Bar Cake is definitely a retro childhood favourite and a fantastic rainy day bake to make with the family (no matter what their age) A chewy gooey cereal base blended with melted Mars Bars and topped with milk chocolate and white chocolate swirls - what's not to love? 

Method

  1. Prepare a 20cm square baking tin, by lightly greasing it and lining it with baking paper.

  2. In a heatproof bowl, heat the butter, golden syrup and 3 of the chopped Mars Bars until they have melted. Don't worry if the Mars Bars do not full melt at this point. 

    • 100g Butter (Unsalted, Softened)
    • 3 Mars Bars (Chopped)
    • 1½ tbsp Golden Syrup (we like Silver Spoon)
  3. Add the Rice Krispies into the bowl and stir in with the remaining Mars Bar.

    • 150g Rice Krispies
    • 1 Mars Bars (Chopped)
  4. Pour the mixture into the baking tin and press down firmly (we used a potato masher for this)

  5. In another heatproof bowl, melt the milk chocolate, stirring until smooth, then pour over the top of the Krispie mixture. 

    • 350g Milk Chocolate
  6. Moving quickly before the milk chocolate sets, melt the white chocolate and drizzle in lines up and down the surface of the Mars Bar slice. Using a skewer, drag forward and back through the mixture to create a feathered effect.

    • 50g White Chocolate
  7. Place the baking tin in the fridge to chill and set. Remove a little while before you plan to serve so that it is easier to cut into squares.

    Made this for a cake sale and it was the first to disappear! I doubled the recipe as Ruth Street suggested, but should have trebled it as there was none left to eat at home! I have used supermarket own brand versions of mars bars and it was just as delicious. Rather than melting the white chocolate for the topping I have also decorated with a scattering of white chocolate shavings. Now making a batch for a birthday party. Great recipe.
