About the bake
The humble Mars Bar Slice is definitely a retro childhood favourite and a fantastic rainy day bake to make with the family (no matter what their age). A chewy gooey cereal base blended with melted Mars Bars and topped with milk chocolate and white chocolate swirls - what's not to love?
Find out below how to make mars bar squares.
Method
Step 1:
Prepare a 20cm square baking tin, by lightly greasing it and lining it with baking paper.
Step 2:
In a heatproof bowl, heat the butter, golden syrup and 3 of the chopped Mars Bars until they have melted. Don't worry if the Mars Bars do not full melt at this point.
Step 3:
Add the Rice Krispies into the bowl and stir in with the remaining Mars Bar.
Step 4:
Pour the mixture into the baking tin and press down firmly (we used a potato masher for this)
Step 5:
In another heatproof bowl, melt the milk chocolate, stirring until smooth, then pour over the top of the Krispie mixture.
Step 6:
Moving quickly before the milk chocolate sets, melt the white chocolate and drizzle in lines up and down the surface of the Mars Bar slice. Using a skewer, drag forward and back through the mixture to create a feathered effect.
Step 7:
Place the baking tin in the fridge to chill and set. Remove a little while before you plan to serve so that it is easier to cut into squares.

Recipe Reviews
Fantastic recipe, really easy. I added marshmallows as well!
Absolutely delicious
These completely fell apart on me! I feel Mars bars in 2023 are far smaller and will try 5-6 next time !
A very firm favourite!
