Prepare the fondue pot: Place the fondue pot over a low heat source.

Melt the chocolate: Add chocolate chips, heavy cream, milk, and butter to the fondue pot. Stir continuously until chocolate is melted and smooth.

Add vanilla: Stir in vanilla extract.

Keep warm: Once melted, reduce heat to low and keep the fondue warm, stirring occasionally.

Dip and enjoy: Dip fruit, marshmallows, and cookies into the fondue.

Tips:

For a richer flavor, use dark chocolate instead of semisweet chocolate.

Add a pinch of cinnamon or cayenne pepper for a spicy kick.

For a fun twist, add a shot of liqueur or brandy to the fondue.

Serve with a variety of dipping items to suit everyone's taste.

Enjoy your decadent chocolate fondue!
