- Holiday sprinkles or crushed peppermint (optional)
- ½ cup white chocolate chips (for drizzle, optional)
- Silicone half-sphere mold (2-inch size recommended)
- Food-safe brush or spoon
DIRECTIONS
- Step No.1: Melt the chocolate
In a microwave-safe bowl, melt the chocolate chips in 30-second intervals, stirring each time until fully smooth and glossy.
- Step No.2: Coat the mold
Use a spoon or brush to coat each mold cavity with melted chocolate. Chill in the fridge for 10 minutes, then repeat with a second layer. Chill again until set.
- Step No.3: Remove chocolate shells
Gently pop the chocolate halves from the mold. Handle carefully to avoid cracking.
- Step No.4: Fill the shells
Add 1 tablespoon hot cocoa mix and a few mini marshmallows into half of the chocolate shells.
- Step No.5: Seal the bombs
Warm a plate in the microwave. Press the rim of an empty half-shell against the plate to slightly melt the edge, then press it onto a filled half to seal. Repeat.
- Step No.6: Decorate the bombs
Melt white chocolate chips and drizzle over the bombs. Add festive sprinkles or crushed candy canes for a holiday touch.
- Step No.7: Serve or package
To serve, drop one bomb into a mug and pour over hot milk. Stir to enjoy! To gift, wrap individually in cellophane.

TIPS FOR SUCCESS
- Use Quality Chocolate: Real chocolate (not candy melts) gives the best flavour and a rich, smooth finish.
- Double Coat the Molds: A second layer of chocolate ensures stronger shells that won’t crack.
- Chill Between Steps: Refrigerating helps the chocolate set quickly and makes shell removal easier.
- Use a Warm Plate: Melting the shell edges on a warm plate creates a clean, sealed bond.
- Handle Gently: Chocolate shells are delicate—use gloves if needed to avoid fingerprints or melting.
- Decorate Quickly: Add sprinkles while the drizzle is still wet so they stick well.
- Store in Cool Place: Keep cocoa bombs away from heat to prevent softening or blooming.
VARIATIONS
- Peppermint Blast: Add crushed candy canes inside the bomb and sprinkle more on top for minty magic.
- Mocha Bombs: Mix instant coffee granules with the cocoa mix for a caffeinated twist.
- Salted Caramel: Add caramel bits inside and drizzle with melted caramel for a sweet-salty surprise.
- White chocolate delight: Use white chocolate for the shell and mix with vanilla cocoa mix inside.
- Spicy Mexican Cocoa: Add a pinch of cinnamon and cayenne to the cocoa mix for a bold, warming sip.
- Nutty Crunch: Include chopped hazelnuts or almonds inside the shell for added texture.
- Matcha Green Tea: Use white chocolate shells filled with matcha latte mix for a non-traditional festive option.
