1Make the sauce by whisking together one tablespoon of butter, two tablespoons of brown sugar, one tablespoon of cream, and a pinch of salt in a microwave-safe container.
2Microwave the sauce mixture in 30-second intervals until melted and smooth, then set aside to thicken.
3In a separate 12-ounce microwave-safe bowl, combine the dates with the remaining butter, remaining cream, and baking soda.
4Microwave the date mixture for 30–60 seconds, then mash into a paste.
5Stir in the flour, remaining sugar, cinnamon, and salt into the date paste until just combined.
6Microwave the batter for 45–60 seconds until the top is set.
7Serve warm topped with the prepared caramel sauce and a dollop of ice cream or whipped cream.
