Add ice cream, milk, vanilla bean seeds, cinnamon, and nutmeg to a blender. Tip: For extra richness, use slightly softened ice cream.

Blend on medium speed until smooth and creamy, about 30 seconds. Tip: Pulse first if your blender struggles with thick mixtures.

Taste and adjust sweetness with honey or maple syrup if desired. Tip: Add a pinch of salt to enhance flavors.

Pour into chilled glasses and serve immediately with a straw. Tip: Rim glasses with cinnamon sugar for a festive touch.
