If you're up for a good choc-fest, then this could well be the cake for you! You could also bake cupcakes for a quick-to-grab treat for morning tea. Source: Super Food Ideas

Yum! This was super easy to make & looks delicious with all the caramelised chunks of mars bar on top - great recipe! I did half the size though (8) and it only took about 35mins to cook so keep an eye on it as you want it soft & chewy not dry : )

absolutely scrumptious!!! easy as too. I am not happy with the calories .....but as an impressive thing for dinner guests, I am sure they will be pleased. I havn't put the mars bars in the top as suggested, I have melted one into a white chocolate ganache (to make a caramel icing), and then I am going to chop up the other one on top as a decoration. Thanks a bunch. Well done!
