A lighter version of the classic hot buttered rum batter that uses Greek yogurt to cut the heaviness without sacrificing flavor. Quick to make, stores beautifully, and delivers that nostalgic, spiced warmth in a mug.
The batter can be stored in the refrigerator for up to 3 weeks or frozen for up to 3 months. For best flavor, make at least 24 hours ahead. If the batter separates in the fridge, let it sit at room temperature for 10 minutes and stir vigorously. For a dairy-free version, use plant-based butter and coconut yogurt. For a lower-sugar option, reduce brown sugar to 3/4 cup and add an extra tablespoon of honey.
