We don't own any Duplo. We skipped over it and went straight to 'proper' Lego since we've collected bucketloads of the stuff since I was small (besides, they don't do Star Wars Duplo). So Creative Cakes was a completely new (kind of) play experience for us all.
The set comes in a reasonably strong cardboard box, with a plastic lid that doubles as a tray for your baked creations. The briefest mention of the word 'cake' was enough to capture my (note quite) 2 year old's attention and she sat for ages clicking the bricks together to make a variety of vaguely cake-shaped objects.
It's Lego and therefore very hard to fault in any way, however I will nitpick at it being very, very pink. As far as I am aware it is common for both girls and boys to have a play kitchen/shop/similar, which this set would compliment very nicely. Unfortunately since - for no really good reason - the colour scheme is heavily girl-targeted, very few boys are going to want it - or at least not be bought it by an adult. Which is a shame because, as I said, this goes perfectly with a play kitchen.
(If there is indeed a more gender-neutral set available, then I apologise.)
Other than that, this is a great set with just enough pieces to allow a number of different cakes to be made. Included is a booklet with some ideas pictured, but really the cakes are all down to the imagination of the child.
