Mix well with a spoon the honey and peanutbutter together in a large bowl. Add the dry milk and stir until well-mixed. (This requires some arm muscles!) Roll small walnut-sized balls with your palms and place on a plate. Cover with plastic wrap or place in a sealable plastic container. They can stay at room temp. As long as they are covered. They last about 3 days around our house, but can last as long as 3 weeks. These little balls are full of protein (and, yes, fat-but that shouldn't be a concern for kids under 5 or so!).
