Baking is a great place for kids to express their creativity. I use a quick baking multi-grain mix from Trader Joes or Arrow mills gluten free multi-purpose baking mix. The dough only needs to be kneaded 8 to 10 times and bakes in 10 mins. It's perfect for a quick activity in that there is no waiting time for rising dough.
We end up with all sorts of lovely creations that we love to smother with freshly made butter and honey. yum! If you don't have a butter churn you can put heavy cream into a glass jar and shake or even easier is to just whip it in a bowl with a whisk. You'll get whipped cream first- and everyone gets a lick and then butter next. It is a great way to watch the whole process and the quickest I find.
