Equipment

  • 1 microwave-safe bowl
  • 1 rubber spatula
  • 2 half-sphere molds with 6 wells preferably silicone; 2-inch molds
  • 1 pastry brush preferably rubber-bristled
  • 1 griddle or wide, flat pan

Ingredients

Hot Cocoa Mix

  • 1 cup powdered sugar
  • 1/2 cup unsweetened cocoa powder

Hot Cocoa Bombs

  • 12 oz semi-sweet chocolate chips
  • 1 1/2 cups mini marshmallows
  • add-ins as desired: peppermint bits, cinnamon, holiday sprinkles, etc. (optional)

Instructions

  • Mix all of the ingredients for the hot cocoa mix together in a bowl and set aside.
  • Put the chocolate chips into a microwave-safe bowl and heat in the microwave for no more than 30 seconds at a time, stirring thoroughly (at least 1 min) in between, until the chocolate is fully melted.
    NOTE: Don't burn the chocolate! This shouldn't take more than 2 turns in the microwave. Most of the melting will actually happen in between heating, when you stir the chips in the warm bowl.
  • Apply ~1 tbsp of melted chocolate to each well and use a pastry brush to spread the chocolate around, coating the walls of each half-sphere evenly.
  • Refrigerate the molds for 5 minutes until they are just set.
  • Remove the molds from the refrigerator. Using the leftover chocolate from the bowl, add a small layer around the top rim of each half-sphere, just inside the well, to reinforce the chocolate where the cocoa bombs will be sealed.
  • Refrigerate the molds for 5-10 minutes.
  • Prepare any add-ins you have selected. Make sure bags and containers are open and easily accessible, so you can move quickly in the next steps.
  • Heat your griddle or a wide, flat frying pan until the surface is just hot to the touch, sufficient to melt chocolate.
  • Remove the molds from the refrigerator. Work carefully to pop each half-sphere of chocolate free of the silicone molds.
  • Take a half-sphere and press the edges down lightly on the hot griddle or pan, holding for a few seconds until the chocolate has just begun to melt.
  • Working quickly, fill the shell with 1 tbsp of the hot cocoa mix, plus ~6 mini marshmallows and any other add-ins you prefer
  • Take a second half-sphere and heat the edges as before, then press it tightly to the half-sphere you just filled, to form a complete chocolate sphere. Hold for a few seconds to let the chocolate cool and harden. Using your finger or a rubber spatula, smooth the melted chocolate along the seam.

  • Repeat the steps above with the remainder of the half-spheres, until you have 6 complete hot cocoa bombs! If desired, drizzle with more melted chocolate and add sprinkles for decorations.
  • To enjoy: Simply place the hot cocoa bomb in a mug and pour hot milk over top. Watch as the hot milk dissolves the chocolate, and your marshmallows and cocoa ingredients spring free!
