In a small microwave safe bowl, melt 2 cups semi sweet chocolate chips in 30 second increments, stirring in between. This should take 60-90 seconds. Once melted, spoon about 2 TBS into each half sphere and using a pastry brush or the back of a spoon, spread the chocolate around the whole sphere making sure the edges are well coated so that they are not fragile. Let set in the fridge or freezer until hardened, about 10 minutes. Once set, gently remove from the molds.

Lay 6 half spheres on a plate, face down. In a small, microwave safe bowl, melt remaining ¼ cup semi sweet chocolate chips in 30 second increments, stirring in between. This should take 30-60 seconds. Once melted, spoon into a baggie or piping bag. Snip a small corner in the bag. Drizzle 5 halves (tops) with chocolate. Place several mini multi colored chocolate chips on top of the drizzle before it hardens. Repeat with 5 more half spheres. Let set in the fridge or freezer for 3-5 minutes until hardened.

Lay the 6 remaining, plain half spheres face up on a plate. Spoon 1 TBS of hot chocolate mix into each half sphere. Top with one piece of cosmic brownie (optional) and several mini marshmallows.

Warm a small microwave safe plate in the microwave for 45-60 seconds. Lay decorated, empty half sphere on the plate for a couple seconds until it begins to melt the edges. This creates an even edge and a sort of glue. Connect with the corresponding, filled half sphere so that the edges meet. Repeat with the remaining 5 spheres until they are all completed.
