Making Sticky Date Self-Saucing Pudding is a straightforward process when you follow these easy steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a baking dish (approximately 8×8 inches).
2. Prepare the Dates: In a bowl, combine the chopped dates and baking soda. Pour in 1 ½ cups of boiling water and let it sit for about 10 minutes until softened.
3. Mix Dry Ingredients: In another bowl, whisk together the flour, baking powder, and salt. Set aside.
4. Cream Butter and Sugar: In a large mixing bowl, beat the softened butter and brown sugar until light and fluffy.
5. Add Eggs and Vanilla: Add the eggs, one at a time, beating well after each addition. Mix in the vanilla extract.
6. Combine Mixtures: Gradually fold the dry ingredients into the butter mixture, alternating with the date mixture. Stir until just combined.
7. Pour into Dish: Pour the batter into the prepared baking dish, spreading it evenly.
8. Prepare the Sauce: In a separate bowl, combine the brown sugar, cornflour, and 2 cups of boiling water. Stir until smooth.
9. Pour Sauce Over Batter: Carefully pour the sauce over the pudding batter in the baking dish.
10. Bake: Place the dish in the preheated oven and bake for 40-45 minutes, or until the top is set and a skewer inserted comes out clean.
11. Cool Slightly: Remove from the oven and let it cool for about 10 minutes. The pudding will continue to self-sauce as it sits.
