Make the Date Puree: In a saucepan, add the dates and water and bring to a boil on high heat, then let it simmer on low heat for 10-15 minutes until the dates are soft, and most of the water has evaporated. Transfer the dates (with the remaining water) into a blender and blend until completely smooth. Let the date puree cool before using.
215 grams pitted dates, 100 ml water
Preheat the oven to 170 degrees Celsius and prepare the 7" square pan with parchment paper or butter.
Combine the dry ingredients in a bowl - flour, baking powder, baking soda, and salt.
200 grams all-purpose flour, 1 tsp baking powder, 3/4th tsp baking soda, 1/2 tsp salt
Add eggs and brown sugar in a separate bowl and mix using a hand whisk until combined, 2-5 minutes. Add the melted butter and mix again until combined.
2 eggs, 185 grams packed brown sugar, 50 grams brown butter, melted and cooled
Add the dry ingredients to the batter in 3 parts and fold them in using a silicone spatula until fully combined.
Once the dry ingredients are fully mixed into the liquid ingredients, add the cooled date puree and fold it into the batter using a silicone spatula until combined. Transfer the batter to the prepared pan and bake for 25-30 minutes, until the pudding is set in the center but still soft. A toothpick should come out with a few crumbs. While the pudding bakes, make the butterscotch sauce.
Make the Butterscotch Sauce: Add all the ingredients to a saucepan and cook on medium-high heat while stirring until the butter melts. Once the sauce starts boiling, bring the heat down and let it simmer for 60-90 seconds until the sauce thickens. Take off the heat and blend immediately.
120 grams brown butter, 210 ml liquid whipping cream/heavy cream, 265 grams packed brown sugar
Once the pudding is baked, poke holes in it using a fork and pour a generous amount of sauce while the cake is still hot. Let the cake soak in the sauce for 30 minutes before serving. PS: Don't forget to save some sauce for serving!
Serve warm with ice cream and extra butterscotch sauce.
