In a small saucepan over medium heat, bring the heavy cream to a gentle simmer, stirring occasionally.
Once simmering, remove the saucepan from the heat and add the white chocolate chips. Stir until the chocolate is fully melted and the mixture is smooth.
Add the ground nutmeg and vanilla extract to the chocolate mixture, stirring to combine.
Pour the mixture into a bowl and cover it with plastic wrap. Refrigerate for about 2 hours or until it's firm enough to scoop.
Once firm, use a small cookie scoop or spoon to portion out the truffle mixture. Roll them into balls quickly with your hands.
Placing the crushed graham crackers on a plate, roll each truffle in the crumbs, ensuring they’re evenly coated.
Place the truffles on a parchment-lined baking tray and refrigerate for another 30 minutes to set.
Before serving, dust the tops with a pinch of extra ground nutmeg for a festive touch.
