Melt the butter in a large pot over medium heat.

Once the butter has melted, add in the marshmallows and mix often.

Once the marshmallows melt, add in the peanut butter and mix thoroughly.

Remove from heat once everything is integrated and mix in the chow mien noodles.

Take small handfuls of the mix (a little bigger than the size of a golf ball) for each nest. Mold into a nest shape or grease a muffin pan to press into the muffin mold for the nest shape.

Press three M&Ms into the nest.

Serve immediately or let sit for an hour for a firmer, less sticky bird nest.
