You will need:
Mini marshmallows
Buttercream
Cupcakes (of course)
Scissors
Souffle cups
Red marker (sharpie)
Stickers (printed)
Ok so get your marshmallow and place it in your hand:
Make a cut half way in, don't cut all the way otherwise you will cut it in half and we don't want that:
Like so:
Now turn it 180 and cut again, we want a criss cross pattern::
Press down on it so it looks like popcorn:
This is the finished popcorn:
Take your cupcake and spread a little bit of buttercream on top:
Place it upside down on top of the "popcorn" you did and press lightly:

If the buttercream hasn't dried out they will stick very easily:
I did the "butter" effect with my airbrush on half of them:
And "au naturale"
All together now:
