Ingredients

For base

  • 7.36 oz mars bars US: milky way - 7.36oz is 4 regular-size bars
  • 7 tablespoon unsalted butter
  • 4 cups rice krispies ie puffed rice cereal

For chocolate topping

  • 9 oz milk chocolate or can use dark, semisweet
  • 1 tablespoon coconut oil

Instructions

  • Lightly butter a baking pan/tin that's 9 x 9 in (23 x 23cm) and at least 1 in (2.5cm) deep. Line it with parchment, at least on the bottom and two sides with slight overhang so you have something to lift out when done. The butter helps the parchment hold in place.
  • Roughly cut up the mars bars/milky way bars and butter into chunks. Place both in a large, wide pot over a medium-low heat and warm, stirring now and then, so that everything melts and combines. Once the mixture is all melted and well combined, add the rice krispies and quickly mix so that the cereal is well coated in the mixture.
  • Pour the mixture into the prepared pan/tin and press it down evenly, flattening the top with a spatula or wooden spoon. Work relatively quickly as it will become harder to wrk with as it cools, which happens relatively quickly. Refrigerate for around 30 minutes to firm up before adding the chocolate.
  • Melt the chocolate and coconut oil together (I usually place in the microwave for 30-40 second intervals, stir, heat again then stop once it is almost melted and melt the last using the heat in the dish). Pour the chocolate over the rice krispie layer and spread evenly, right to the edges. Try not to over work the chocolate as you will just make it more uneven as it firms up.
  • Place the pan in the fridge again to harden for around 30 minutes, if not a little longer, until the top is dry and firm. Use the parchment around the edges to lift the whole block from the pan and then cut into pieces. You may find it helpful to score first and/or use a warmed knife to help cut the chocolate layer without it cracking.

Notes

In the UK and Australia, the bars you are looking for are Mars Bars, in the US look for Milky Way - it's the bars with a base of nougat, topped with caramel and a chocolate coating. 
You don't have to include oil in the topping, but it does help to reduce the chances of the chocolate cracking as you slice. Alternatively, dip or run your knife in boiling water in between cuts to help cut through the chocolate layer without too many cracks.
I used a 9x9in pan for this, but 8x8in (20x20cm) will also work with just slightly thicker layers.
