Equipment: Silicone hemisphere mold(s) with 16 (1-oz.) cups; parchment paper
(Molds are available in baking supply stores and online, such as these from Amazon. Each product we feature has been independently selected and reviewed by our editorial team. If you make a purchase using the links included, we may earn commission.)
To make ahead: Refrigerate hot chocolate bombs (Steps 1-6) in an airtight container for up to 1 month; bring to room temperature before serving.
Tip: Dehydrated marshmallow bits are tiny marshmallow pieces like you get in packets of hot cocoa mix. Look for them near the other marshmallows at the supermarket or find them online.
