In a spacious mixing bowl, crack the eggs and add the powdered sugar. Whisk together vigorously until the mixture is smooth and creamy, with no lumps remaining.
Gradually pour in the whole milk and heavy cream to the egg-sugar mixture. Continue whisking until everything is well integrated and the mixture appears homogenous.
Incorporate the pure vanilla extract, ground cinnamon, ground nutmeg, and a pinch of salt. Stir gently until the spices are evenly blended into the mixture.
Carefully transfer the eggnog mixture into a large saucepan. Heat it over low heat, stirring frequently to prevent spillage. It’s crucial not to let it boil; the goal is to gently warm the eggnog to avoid curdling the eggs.
After approximately 10 minutes, once the mixture is warm but not bubbling, take it off the heat and allow it to cool at room temperature for a while.
For an exceptionally creamy texture, use an immersion blender or a traditional blender to blend the eggnog for about 30 seconds until frothy and smooth.
Next, place the eggnog in the refrigerator and chill for at least 2 hours, or until thoroughly chilled.
To serve your delightful eggnog, pour it into festive glasses, generously dollop whipped cream on top, and adorn with a cinnamon stick for that perfect finish.
Notes
For an extra festive touch, sprinkle a pinch of cinnamon on top of the whipped cream before serving.
