Hey Angie, no I don't find the blueberries too heavy. I put one punnet of blueberries and 1 punnet of raspberries. It is a very rich cake as it has 3 packets of Philadelphia cream cheese and a carton of cream so the slices aren't too big.
@CandiceMarie no they don't really do pick and mix ( unless you count the fresh nuts) like Callyanna said it is a supermarket. We call it Woolies too. I'mglad it brought back some nnice memories for you.
