Line a small square baking pan [one with a lip, a brownie pan will do!] with foil and rub with a little bit of butter or oil to prevent sticking or use some naturally non-stick parchment paper!

In a medium pot, melt butter over medium-low heat.

Add 4.5 cups marshmallows and whisk/stir until smooth and melted, about 5 minutes.

Remove pot from heat.

Using a moistened spoon, fold in the cereal.

Add the chocolate, salt, and an extra 1/4-1/2 cup of marshmallows and fold it in as well, moving fast as the gooey melted marshmallow will set fast.

Spoon onto your baking pan and press into an even layer, as thin or thick as you would like.

Use a sifter or dusting wand to dust with powdered sugar [optional but prettty!] and allow to cool.

Cut into squares to gift or scarf!
