Mars Bar Slice Recipe

Printer-friendly versionPrinter-friendly version

An all-time favorite, we like to make ours ‘gooey’ and not too solid, so you can actually see the Mars bar filling when you cut into it. This is a great recipe if you want to get the kids involved – never mind the mess! We have also added another recipe here to use up the rice cereal that you have bought and to give an extra treat on the plate! Ours are fatter pieces or chunks, but if you use a different size dish they will be more of a slice – these are intended to look more like brownies.

Serves:  12 pieces
Preparation Time: 15 minutes
Cooking Time: 10-15 minutes
Chilling Time: 30 minutes



5 x 2 oz Mars Bars (or your favorite candy bar), chopped into smallish pieces
1 tbs of runny honey
2 oz butter
4 oz of puffed rice cereal
7 oz milk chocolate



Grease and line a 6 x 8 baking tray (if you have one this size, it makes the end result chunky) if not, your slice will be thinner, but that is up to you, it does not affect the end taste.

Mix butter, honey and Mars bars in a saucepan over a low heat, stirring continuously to prevent sticking or burning. Remove from the heat when all is smooth and melted together. Add the rice cereal and mix together well. Pour the mixture into the lined dish and cool, either at room temperature for about an hour, or in the fridge for 30 minutes (try to keep the warm mixture away from other food as this will heat up your fridge).

Melt the chocolate in a bowl over some simmering water, stirring until the chocolate melts.

Pour the chocolate over the slice, smooth out evenly and leave for 30 minutes to set.
Cut into chunks/slices.



With the remaining rice cereal make TOFFEE MARSHMALLOW SLICES.
3½ oz butter
3½ oz soft toffees
3½ oz marshmallows, shredded
5¼ oz of rice cereal (or approx 3½ cups)

Mix butter, marshmallows and toffees in a saucepan over a low heat until melted together, stirring continuously (should take about 5 mins). Remove from heat and stir in the rice cereal.

Pour into the tin and smooth out evenly. Cool in the fridge or at room temperature. Cut into chunks or thinner slices as desired.
