Microwave 2 cups semi-sweet morsels and 2 tablespoons shortening in medium, uncovered, microwave-safe bowl on HIGH (100%) power for 1 minute. Stir until smooth. Paint the chocolate into the silicone molds to create a thin layer on the insides. Remove excess chocolate.

Repeat Step 1 with 2 cups semi-sweet morsels and remaining 2 tablespoons shortening and then repeat process with remaining molds. Place molds into refrigerator to set.

Once set, gently remove chocolate half spheres from molds and place on a sheet of parchment paper or clean work surface. Fill 6 of the half spheres with 2 tablespoons of NESCAFÉ Clásico, 1 tablespoon of hot chocolate mix, a pinch of mini morsels and marshmallows.

Using a shallow microwave-safe bowl, melt remaining 3 tablespoons semi-sweet morsels in microwave according to package instructions. Pipe the melted morsels onto the lip/edge of one of the empty half spheres. Top one of the filled half spheres with this one to create a full sphere. Repeat with remaining half spheres. Refrigerate to set before using.
