Bring eggs, sour cream, and eggnog to room temperature before mixing to ensure even incorporation and create a lighter, fluffier crumb structure in your donuts.

Mix wet and dry ingredients until just combined—overmixing develops gluten and creates dense, tough donuts instead of the desired soft and tender texture.

Toast the ground nutmeg briefly in the melted butter before mixing to intensify its warm spice flavor and eliminate any raw, bitter notes in the final donuts.

Dip donuts into the eggnog glaze while still slightly warm from the oven so the glaze adheres perfectly and creates a thin, glossy coating that sets beautifully.

Use high-quality, full-fat eggnog (not diet or egg substitute versions) for authentic rich flavor and better moisture retention throughout baking and storage.
