📝 Instructions

11 steps
1

Grease and line a 9-inch square baking pan with parchment paper, leaving some overhang for easy removal.

2

Chop the Mars bars into small pieces and add them to a heatproof bowl along with the butter and golden syrup.

3

Place the bowl over a saucepan of simmering water, ensuring the bottom of the bowl does not touch the water. Stir the mixture gently until the Mars bars and butter are fully melted and smooth.

4

Remove the bowl from the heat and immediately fold in the crisp rice cereal, ensuring the cereal is evenly coated with the melted mixture.

5

Press the mixture firmly into the prepared baking pan using the back of a spoon or an offset spatula to create an even layer.

6

Allow the base layer to cool slightly while you prepare the chocolate topping.

7

Chop the milk chocolate and dark chocolate into small pieces and melt them together using the same double-boiler method or in the microwave in 30-second bursts, stirring between intervals.

8

Pour the melted chocolate over the crisp rice base and spread it evenly using a spatula.

9

Let the cake cool to room temperature, then transfer it to the refrigerator to set for at least 2 hours.

10

Once set, lift the cake out of the pan using the parchment paper overhang and place it on a cutting board.

11

Slice the Mars Bar Cake into 12 equal squares or rectangles, and serve. Enjoy!
