Mix all the ingredients except the puffed wheat in a saucepot, and bring to a boil.
Pour over the puffed wheat (in a large bowl) and stir with a spatula until everything is coated.
Pour into the baking pan and spread evenly. Press down very firmly with a spatula.
Let cool. Cut into squares (big or small as desired).
Cover with plastic wrap and keep on the counter.
Notes
If they last a couple days you can store in the fridge, but they will probably only last an hour or so. Or make batches, cut them up, and store in the freezer!
