Make the Caramel Sauce: Combine butter (1 tbsp), brown sugar (2 tbsp), heavy cream (1 tbsp), and salt (pinch) in a small microwave-safe bowl. Microwave in 30-second intervals, stirring between intervals until melted and smooth. Set aside to thicken.
Make the Pudding Batter: Place dates (2), butter (1 tbsp), cream (2 tbsp), and baking soda (¼ tsp) into a separate 12-ounce microwave-safe bowl. Microwave for 30 to 60 seconds until dates soften. Mash the mixture thoroughly into a smooth paste.
Add flour (¼ cup), sugar (1 tbsp), cinnamon (⅛ tsp), and salt (pinch) to the date paste. Stir until just combined (do not overmix).
Cook and Serve: Microwave the batter for 45 to 60 seconds until the top is set. Pour the caramel sauce over the warm pudding. Top with a dollop of ice cream or cream.
