Preheat broiler to HIGH.

Place marshmallows on a large baking sheet lined with parchment paper. Space marshmallows so few are touching each other. Broil marshmallows on HIGH for 2 minutes or until they reach desired toasty-ness. (Do not step away... these suckers brown fast!)

Place 1 cup toasted marshmallows in a blender or food processor. Add avocados and remaining ingredients. Pulse until completely smooth. Stir in remaining 1/2 cup toasted marshmallows.

Transfer mixture to a popsicle mold; insert wooden sticks, cover, and freeze.
