1-First Step: Prepare your workspace Melt 10 ounces of the chocolate coating in a microwave-safe bowl. Heat in 30-second bursts, stirring until smooth. Reserve 2 ounces for sealing.

2-Second Step: Mold the chocolate shells Spray silicone sphere molds (2.5-inch size) lightly with oil. Spoon melted chocolate into each cavity, about 1-2 tablespoons per half-sphere. Rotate to coat evenly, tap out excess, and refrigerate for 5 minutes.

3-Third Step: Unmold the halves Pop the chilled chocolate shells from molds. Handle gently; they firm up quickly. Prepare 6 bottom halves and 6 top halves. If cracks appear, patch with extra melted chocolate.

4-Fourth Step: Fill the bottoms In each bottom half, add 1 tablespoon hot cocoa mix, 8-10 mini marshmallows, and a pinch of sprinkles. Avoid overfilling to ensure easy sealing.

5-Fifth Step: Seal the bombs Warm a plate in the microwave for 30 seconds. Press open edges of filled bottoms and tops onto the hot plate briefly to melt slightly. Join halves quickly, sealing tightly. Wipe away drips with a warm cloth. Re-melt reserved chocolate if needed for touch-ups.

6-Sixth Step: Decorate and set Drizzle tops with remaining melted chocolate. Add more sprinkles or crushed candy canes. Let set at room temperature or chill 5 minutes.

7-Final Step: Serve your creation Drop one hot cocoa bomb into 8-12 ounces hot milk. Watch it melt and release fillings for instant delight. Stir gently.
