Melt the chocolate by placing 1 cup of white chocolate and 1 tablespoon of vegetable shortening in a microwave-safe bowl. Heat in the microwave for 30 seconds at a time, stirring until smooth and glossy.

Assemble the marshmallow base by dipping the bottom of a large marshmallow into melted chocolate and pressing it onto a parchment-lined baking sheet. Stack two more marshmallows on top using the chocolate as glue.

Allow the base structure to set slightly at room temperature for about 5-10 minutes, or refrigerate for a quicker setting.

Coat the figure with remaining melted white chocolate using a spatula for an even coat. Press candy eyes onto the marshmallow figure before the coating sets.

Let the coating harden fully at room temperature for 15-20 minutes, or refrigerate for a quicker process.

Add the finishing touches by dusting with powdered sugar and using the black edible marker to draw playful smiles.
