This is a yummy recipe that we make year-round. At Christmas time, spruce it up with a glazed fruit topping.

Line a 9 x 9 square baking pan with wax paper, leaving a 5 cm overhang on opposite sides. 

Mix the marshmallows and walnuts in a large mixing bowl and set aside. Combine the condensed milk, butter, and chocolate chips in a large saucepan. Cook over medium heat, stirring frequently until melted and smooth. Allow to cool for 5 minutes. Pour the chocolate mixture over the marshmallow mixture and mix until thoroughly combined. Pour the mixture into the prepared pan and smooth the top with a buttered spatula. Pile the glazed fruit over the top while the chocolate mix is still warm.

Put the pan in the fridge for 2 hours or until set.

Using the wax paper overhang, lift out of pan and place on a cutting board. With a sharp knife, cut into bars, cleaning the knife blade between cuts.

I used 300 g of dark chocolate instead of 2 cups chocolate chips, it is less sweet and sets quicker and to a harder texture than chocolate chips.
