Creating Sticky Toffee Pudding Cake is straightforward if you follow these simple instructions:

1. Preheat Oven: Begin by preheating your oven to 350°F (175°C). Grease and flour an 8-inch square baking dish.
2. Prepare Dates: In a bowl, combine chopped dates and baking soda. Pour boiling water over the mixture and let it sit for about 10 minutes.
3. Mix Butter and Sugar: In a separate bowl, beat the softened butter and granulated sugar together until it’s light and fluffy.
4. Add Eggs and Vanilla: Mix in the eggs one at a time, followed by the teaspoon of vanilla extract.
5. Combine Dry Ingredients: In another bowl, whisk together the all-purpose flour, baking powder, and salt.
6. Combine Mixtures: Gradually add the dry mixture to the butter and sugar blend, alternating with the date mixture until everything is well incorporated.
7. Pour Batter: Pour the batter into the prepared baking dish and smooth the top with a spatula.
8. Bake: Place in the oven and bake for 35-40 minutes, or until a skewer inserted in the center comes out clean.
9. Make the Toffee Sauce: In a saucepan, combine heavy cream, brown sugar, dark corn syrup, and the additional teaspoon of vanilla. Bring to a gentle boil, then simmer while stirring for about 5 minutes until it thickens slightly.
10. Cool the Cake: Once fully baked, remove the cake from the oven and let it cool in the pan for about 10-15 minutes.
11. Serve Warm: Cut into squares and generously drizzle the warm toffee sauce over each slice.
