This make-ahead hot buttered rum batter is the ultimate cold-weather crowd-pleaser. With simple pantry ingredients and a spiced butter base, it turns a chilly evening into a warm, memorable gathering.
Use room temperature butter for best creaming. Boiling water is essential to fully dissolve the batter. Stir vigorously for about 15 seconds to emulsify. The batter improves after 24 hours in the fridge. For a dairy-free version, use vegan butter and full-fat coconut cream. For a non-alcoholic version, omit rum and add extra boiling water or a splash of rum extract.
