Step 3: The Icing and the Marshmallow

Now that your icing is made and your cookies have cooled, you are ready for the next step...

Place a piece of parchment paper on your work surface and pick a couple of cookies to start with.
Spoon a small puddle of icing onto your cookie and using the back of a spoon or a knife spread it around making sure to go right to the edges in some spots so he looks drippy.

Next, liberally grease a plate or silicone mat with shortening. And place about 8 marshmallows on the mat, spaced out. Set your microwave for 20 seconds and DO NOT WALK AWAY. Watch the marshmallows. As they start to puff up, you are ready to go. Don't let them get huge or melt. You just want them to puff. Stop your microwave BEFORE they double in size.

Liberally Grease your fingers and pick up one marshmallow at a time and kind of smoosh it into place. You don't have to be neat or perfect, just get it on there. The marshmallow should not stick to your fingers as long as you have shortening on them.

Repeat this step for each cookie and then let the icing set up just a bit.
