Meltdown chocolates according to package instructions, do not over melt they can burn. If you need to thin out the green melts add a small amount of coconut oil until it’s a pourable consistency.
Place the plastic cups upside down on a cutting board and using the xacto knife cut a line down the of the cup.
Marble the white and green by pouring them into the same bowl but down fully stir to incorporate.
Pour the marbled chocolate into the cups.
Twist the cup as you do this (to full cover the entire thing).
Turn the cup upside down on a piece of parchment to allow any extra chocolate to drip off and cover the fullness of the cup
Place the cup in the freezer for 7-9 mins to set.
Remove from the freezer.
Add more melted chocolate on top of that filling it 3/4 full
Return to freezer to harden for 18-25 mins
Turn the cup upside down on your cutting board and make cuts in the rim of the cup all the way around it.
Carefully, peel off the cup, starting at the original long slit on the side.
Once the chocolate is released from the cup turn it right side up.
Add a small amount of melted chocolate to the top, add mini marshmallows, peppermint sticks, and sprinkles.
Use melted white chocolate in a piping bag to "glue" on sprinkles and additional marshmallows.
Return to the freezer for a final set, for about 7-8 mins
