In a bag or other container, mix together everything but the marshmallows and the butter.
Set aside.
In a large, microwave dish (see comments), melt the butter, about 1 minute. 
Add marshmallows, tossing generously so that they are well coated with the melted butter, and then moving most of them closer to the center and away from the edges.💡 
Microwave for about 3 minutes or until marshmallows have doubled in volume.
🚫 Don't overdo it or your treats will be in the break-your-teeth stage!
Stir dry ingredients into marshmallows, mixing thoroughly.
Spread evenly into a baking dish or onto a cookie sheet, which should be well coated with butter.
Coat your hands with butter and smooth out the top of the Husky Treats.
I also use a buttered rolling pin.
Allow to cool and then cut them up and serve.
Serving size says 16 2" squares, but I usually cut them in 1" squares.
