Melt the green candy

• Melt the green candy melts in a bowl until smooth.
• Brush the melted candy into the cavities of a cocoa bomb mold, coating the sides evenly.

Chill the shells

• Place the mold on a tray and chill until the shells are set and firm.

Fill the bombs

• Fill half of the shells with the hot cocoa mix and mini marshmallows.
• Warm the rim of an empty shell slightly and press it onto a filled shell to seal.

Decorate the Grinch face

• Melt the red candy melts and pipe a small heart onto the top of each bomb.
• Draw the Grinch's eyes and eyebrows with the black edible marker.

Set and serve

• Let the decorations set, then drop a bomb into a mug of hot milk and stir.
