It's nice to have fun food that is good for you. My kids have always enjoyed sweet snacks and it's not always easy to find ones that are healthy as well. Edible play-dough is fun for toddlers and fun to eat. There are a lot of recipes for edible play-dough which can be found in books and online. My favorite is peanut butter play-dough. This recipe has been around for years; I remember having it as a child and reading recipes in books long ago.
What I really love about this recipe is the versatility of the ingredients. Basically, it is a mixture of one part honey, two parts peanut butter, and two parts powdered milk (or enough of the dry ingredient to make the mixture not sticky). Substitutions for any of the ingredients is very simple. Try sorghum in place of honey, or an almond butter instead of peanut. For someone lactose intolerant, any flour can be substituted for the powdered milk. Yes, it still contains sugar, even though the natural sugars are better, but it is combined with a high level of protein provided by the nut butter and milk. This makes for a fun, easy, protein- and energy-packed snack that is really fun for all ages.
Another strategy for older kids is to combine it with granola or another cereal and press it in a pan. Refrigerate till firm then cut into squares for a nutritious bar.
My youngest son still request peanut butter play-dough for breakfast, and honestly, I don't mind making it for him! I usually make it with local honey and sorghum which keeps his allergies non-existent. Try it, and share with us how you make it!
