Ingredients (Makes 6–8 Bombs)
- 12 oz (about 2 cups) high-quality chocolate (milk, dark, or white chocolate chips/bars — use the good stuff for the smoothest melt)
- 6–8 Tbsp hot cocoa mix (store-bought or homemade)
- ½ cup mini marshmallows
- Optional fillings & toppings: crushed candy canes, sprinkles, caramel bits, mini chocolate chips, peppermint bits, or cinnamon
Tools you’ll need: Silicone half-sphere molds (1.5–2 inch size), pastry brush or spoon, and a baking sheet.
Step-by-Step Instructions
- Melt the Chocolate Microwave or double-boil the chocolate in 20-second bursts, stirring until silky smooth. Don’t overheat!
- Coat the Molds Spoon or brush melted chocolate into each half-sphere cavity, making sure to coat the sides evenly (about ⅛-inch thick). Tap the mold gently to remove air bubbles. Freeze for 5–10 minutes until set.
- Unmold & Fill Carefully pop out the chocolate shells. Add 1 Tbsp hot cocoa mix + 5–6 mini marshmallows (plus any fun extras) into half of the shells.
- Seal the Bombs Warm a plate in the microwave for 30 seconds. Press the empty shell edges onto the warm plate to slightly melt, then gently press onto a filled shell. Twist lightly to seal.
- Decorate Like a Pro Drizzle with extra melted chocolate and sprinkle with crushed candy canes, sprinkles, or gold dust while still tacky. Pop back in the fridge for 5 minutes to set.
- Serve & Watch the Magic Place one bomb in a mug. Heat milk (or milk alternative) until steaming, then pour over the bomb. Stir and enjoy the explosion of marshmallows and chocolatey goodness!
Winter Flavor Twists (Because One Is Never Enough!)
- Peppermint Dream: Add crushed candy canes inside + white chocolate drizzle
- Nutella Heaven: Swap some cocoa mix for a dollop of Nutella
- Spiced Chai: Use chai tea mix + cinnamon in the filling
- Salted Caramel: Mini caramel bits + flaky sea salt on top
- White Hot Chocolate: White chocolate shells + white cocoa mix
Pro Tips for Bomb-Proof Success
- Use good chocolate — cheap stuff won’t melt smoothly or taste as rich.
- Work quickly once chocolate is melted so it doesn’t seize.
- Make ahead: Store finished bombs in an airtight container in the fridge or freezer for up to 2 months.
- Giftable idea: Wrap in clear cellophane with a cute tag and ribbon — instant holiday magic!
