They're just rice krispy treats with tinted melted marshmallow,
...packed into a smallish funnel,
...wrapped in foil (sprayed lightly with non-stick cooking spray)
(with a cute little ribbon--or a strip of paper with a sweet message written on it).

I snip the corners off the foil squares before wrapping the krispy treat. Otherwise, there would be a big wad of foil at the top.
Yum!
Now go give 'em to all the little neighbor kids!
NOTE: I made 2 regular batches of rice krispy treats. Using a funnel that holds about 1 cup of water, I was able to make 16 krispy kisses (8 kisses in each batch). If needed, more can be made using a smaller funnel or just by not filling the funnel up to the top.
For a more authentic chocolatey (and gluten-free!) kiss treat, you can use Cocoa Pebbles. Sadly, krispy rice cereals still contain gluten because of the malt ingredient.
