The chocolate mass is pretty runny and will set on the bottom of the tin. I personally like to rather chocolaty base and the less chocolaty top layer of cornflakes. If you like your bars more balanced allow the mass to cool a little before you add the cornflakes.
When you cut the squares, give the whole block on a cutting board. Use a sharp knife and cut the pieces with a single fast movement.
Store in the fridge and use up within one week
If you have some crumbles left you can use them to top your yoghurt bowls or smoothies. Delicious!
A nice little crunchy treat combining some lovely components. And as it's conflakes I have no worried to dig in as a breakfast as well. Not too strange today but definitely good!
