In four separate, small sized, microwave safe bowls, melt hot pink, orange, yellow and white candy melts in 30 second increments, stirring in between. Once melted, spoon some of each candy melt color into each mold, enough to fill the mold ½ full and spread it around the mold as evenly as possible. If you would like to be extra creative and fun with it, alternately mix and add candy melt colors then use your spoon to lightly swirl the colors together to create a marbled effect. Be sure there is enough candy melt in each mold to thickly cover all sides so there are no thin spots.
Let set until hardened, about 10 minutes. If the top edge of the egg feels thin or delicate, spread just a little more of the candy melt to reinforce it and let set until hardened. Gently remove the eggs from the mold.
In 4 of the egg halves, place 1Tbs of hot chocolate powder, several mini marshmallows and some sprinkles for extra fun. Warm a small plate in the microwave. Place the opposing,empty half of the egg on the plate for 3-5 seconds to let the edges melt. Match the empty half with the filled half and gently press them together. Run a clean finger along the seam to smooth it out. If the halves don’t stay together, you can warm a metal butter knife by running it under hot water then run the warm knife over the edge of the filled half while the empty half is on the plate.
Once all of the hot cocoa bombs are together, serve and enjoy or package and give away!
