Mars Bar Slice

The Mars Bar Slice combines melted Mars bars and butter mixed with puffed rice cereal to form a chewy and crunchy base, topped with a smooth milk chocolate and vegetable oil glaze. After chilling until firm, it cuts into sweet, chocolate-rich bars that balance caramel, nougat, and crispy texture.

Description

This Mars Bar Slice uses chopped Mars Bars melted with butter as the binding base mixed with puffed rice cereal, providing a combination of chewy caramel and nougat flavors with light crunch. After pressing firmly into a lined pan, a smooth layer of melted milk chocolate mixed with vegetable oil is spread over the top, which forms a creamy and shiny finish once set.

The slice is refrigerated for several hours to solidify, allowing easy cutting and firm texture without crumbling. The blend of chocolate and puffed rice creates contrast between smoothness and crispness.

The bars are cut with a hot dry knife to produce neat squares that hold together well. This treat offers indulgent chocolate flavors complemented by the distinctive caramel and nougat from the Mars bars, making it suitable as a sweet snack or dessert.

Notes indicate that using milk chocolate instead of cooking chocolate improves the creamy taste, and persistent separation of the Mars bar and butter mixture during melting should be resolved by stirring off the heat before combining with cereal.

Notes

  • Mars Bars have nougat and caramel covered in smooth chocolate, called Milky Ways in the US.
  • Rice Bubbles, Rice Krispies, or any puffed rice cereal can be used for the base.
  • Use milk chocolate for a creamier topping rather than cooking chocolate.
  • If the Mars bar and butter mixture separates while melting, remove from heat and stir well before mixing with cereal.
