To make the sauce, microwave one tablespoon of butter, two tablespoons of brown sugar, one tablespoon of cream, and a pinch of salt in 30-second intervals until melted and smooth, then set aside to thicken.
In a separate 12-ounce microwave-safe bowl, heat the dates with the remaining butter, cream, and baking soda for 30–60 seconds before mashing into a paste.
Stir in the flour, remaining sugar, cinnamon, and salt until just combined.
Microwave the batter for 45–60 seconds until the top is set, then serve warm topped with the prepared caramel sauce and a dollop of ice cream or whipped cream.
