  • Melt chocolate chips in microwave safe bowl for 30 seconds. Stir. Continue to microwave in 15-second intervals until chocolate chips are melted and smooth.
    DO NOT overheat the chocolate.
  • Add a spoonful of chocolate into 6 chocolate mold cavities. Smooth chocolate up the sides of each mold with a spoon. Add more chocolate as necessary to coat the inside of each mold.
    Let the chocolate sit for a few minutes. Check to see if there are any areas that need to be covered again, then smooth out the sides with a spoon. This will help ensure that the sides and center of the mold are evenly coated with chocolate.
    There will be a little extra chocolate leftover in the bowl. Save this to patch any weak areas or seal the middle seam after the chocolate hardens.

  • Refrigerate chocolate for at least 30 minutes or until completely set.
    Gently remove from the mold.
    6 chocolate cups
  • Fill 3 halve-spheres with 1 tablespoon of cocoa mix and 1 tablespoon of mini marshmallows.

  • You will need a hot bowl or plate. Press one of the empty chocolate cups against the hot plate to slightly melt the rim.

  • Place the empty chocolate cup over one of the filled ones. Work quickly and try not to handle the chocolate too much. The warmth of your hands will leave fingerprints and can soften the chocolate. If you notice this happening just pop the chocolates back into the refrigerator for a few minutes.

  • Run a hot spoon along the seam where the two chocolate cups meet to slightly melt the chocolate and seal the seam. If you have any gaps you can also pipe some melted chocolate over the seam and it will also seal it nice and tight.

DO NOT overheat the chocolate chips. Chocolate can be melted in a double boiler or in the microwave.
The key to success is making sure the chocolate has time to really set up in the refrigerator. If the chocolate is soft (AT ALL) it will stretch and break.
Like any other chocolate project, if you handle the chocolate too much the heat from your hands will cause it to soften. If you find this to be the case while you are smoothing out edges and seams in the chocolate molds, just place the molds back in the refrigerator for 5 minutes or so.
You can use a hot spoon to smooth out the center seam. If your seam doesn't match up perfectly, you can dip your finger in some of the extra melted chocolate and carefully run it along the seam. Refrigerate to allow the seam to harden, then run a hot spoon around the seam to smooth it out a bit. 
Hot chocolate bombs should be stored in an airtight container or in a cellophane gift. Storing them in a pantry or on a counter is fine as long as they are not near a heat source or window.
