Ingredients

• 5 bars (50g each) Mars Bars
• 100 grams Unsalted butter
• 2 tablespoons Golden syrup
• 4 cups Rice cereal
• 2 cups Mini marshmallows
• 200 grams Milk chocolate
• 50 grams White chocolate (optional, for drizzling)

Directions

Step 1

Line a 9x9-inch (23x23 cm) square baking tin with parchment paper, ensuring the edges overhang for easy removal later.

Step 2

Roughly chop the Mars Bars into small pieces. In a medium saucepan, melt the Mars Bars, unsalted butter, and golden syrup over low heat, stirring constantly until smooth and fully combined.

Step 3

Remove the saucepan from the heat and gently stir in the rice cereal. Ensure all the cereal is evenly coated in the melted Mars Bar mixture.

Step 4

Press the mixture firmly and evenly into the prepared baking tin using the back of a spoon or a clean rubber spatula.

Step 5

Sprinkle the mini marshmallows evenly over the rice mixture, gently pressing them down so they adhere to the surface.

Step 6

Melt the milk chocolate in a microwave-safe bowl in 30-second intervals, stirring between each interval, until smooth and fully melted. Pour the melted milk chocolate over the marshmallow layer, spreading it out evenly with an offset spatula or the back of a spoon.

Step 7

If desired, melt the white chocolate (using the same technique) and drizzle it over the milk chocolate layer for decoration.

Step 8

Allow the slice to set in the refrigerator for at least 2 hours or until firm.

Step 9

Once set, remove the slice from the tin using the parchment overhang. Cut into 16 squares with a sharp knife. Serve and enjoy!
