Place the chocolate in a microwave-safe bowl and cook on high for 30 seconds. Stir, then cook for another 30 seconds. Microwaves vary so just melt the chocolate in short bursts, stirring regularly.

Make yourself an assembly line: marshmallows, melted chocolate, sprinkles, and a small baking pan lined with a silicone mat or waxed paper.

Dip each marshmallow in the chocolate, then shake it a little to remove any excess chocolate.

Place it on the baking pan, chocolate side up. Take a pinch of the sprinkles and drop them onto the chocolate.

Repeat with the rest of the marshmallows.

Place the pan in the fridge for 30 minutes to harden. Store in the fridge until required.
