Start by making the red chocolate heart that will go on top of your Grinch hot cocoa bomb. To do this, melt the red candy hearts in the microwave for 30 seconds, stir and repeat until all the chocolate is melted.

Fill each cavity of the silicone heart mold half way and set aside. Allow this chocolate to set as you continue with the additional steps.

Now, it's time to make your hot cocoa bomb shell. Using the bright green candy melts, heat in the microwave for 30 seconds, stir and repeat until all the chocolate is melted.

Carefully spoon the melted green chocolate into the Wilton 3D ball cake pan and then swirl it around using your hands. You want to cover every part of the mold the best you can. Allow this to set for a few minutes.

Repeat the step above until you have 3-4 coats of the chocolate (you want this to be a bit thick to avoid it from cracking upon removal).

Once all of your coats are finished, place the ball pans into the freezer for about 7 minutes and then remove.

Gently flip the pans over and the chocolate should pop right out.

Fill one half of your chocolate mold with the hot cocoa powder and mini marshmallows.

Place a hot plate on top of the chocolate mold to melt the edges and then melt the other half of the chocolate mold.

Place the two halves together and then use your finger to rub the edges of the melted chocolate together (this helps seal the seam of the hot cocoa bomb).

Melt the dark green candy melts and drizzle over the top of the hot cocoa bomb. Now is also the time to place a red candy heart (after removing from the mold) right in the middle on top while the chocolate is still tacky.

Top off with sprinkles and allow the chocolate to set.

Refrigerate or use right away.

Once you are ready to consume it, you can either place this into the bottom of an Instant Pot and pour hot milk over it or simmer hot milk in the Instant Pot and then drop the Grinch Hot Cocoa Bomb inside.

Stir and use a ladle to scoop into individual mugs. Enjoy!
