Ingredients Equipment Method Notes

Ingredients
  

  • 18–24 oz high-quality melting chocolate (milk, dark, or white)
  • 2–3 Tbsp hot chocolate mix powder per bomb
  • mini marshmallows
  • festive sprinkles (optional)
  • crushed candy canes (optional)
  • extra melted chocolate for drizzle (optional)

Equipment

  • Silicone sphere molds For creating hollow chocolate bomb shells.
  • microwave-safe bowls For melting chocolate.
  • pastry brush or spoon To spread chocolate in molds.
  • Warm plate or skillet Used to melt shell edges for sealing.
  • Piping bag or spoon Optional, for drizzling melted chocolate.

Method
 

  1. Gently melt the chocolate using a microwave in 30-second bursts or a double boiler, stirring until smooth and glossy.
  2. Spoon melted chocolate into each silicone mold cavity and spread evenly with a brush or spoon. Chill for 5–10 minutes until set. Apply a second layer for sturdier shells, then chill again.
  3. Carefully remove chocolate shells from molds. Fill half of the shells with 2–3 Tbsp of hot chocolate mix and a handful of mini marshmallows.
  4. Warm a plate or pan slightly. Press an empty chocolate shell edge onto it to melt slightly, then attach it to a filled shell to seal. Repeat with all bombs.
  5. Drizzle with extra melted chocolate and decorate with festive sprinkles, crushed candy canes, or marshmallows. Chill briefly to set.

Notes

Use tempered chocolate for a glossy finish and a crisp snap. Customize fillings with sprinkles, candy cane bits, or cinnamon. Store in a cool, dry place for up to 2-3 weeks.
