The kits are too complicated for a 3 and 5 year old. I can't imagine that and 3 or 5 year old would be able to pour melted chocolate into molds, fill the molds with powdered chocolate and then seal them together with more melted chocolate without hurting themselves. These kids might be appropriate for 10 to 12 year olds. The kit is still in the cupboard. I will save it for another day and let them watch me do it. I did include a picture of the pancake kit that we made. Again ...working with a hot griddle is not something I would allow the three and five-year-old to try.
