1. Prepare Dates: Place chopped dates in a bowl, pour boiling water over them, and sprinkle with baking soda. Let sit for 10 minutes to soften.

2. Mix Wet Ingredients: In a large bowl, combine the brown sugar, egg, melted butter, and vanilla extract. Mix well.

3. Combine Ingredients: Add the softened date mixture to the wet ingredients and stir. Then fold in the flour, walnuts, and salt until just combined.

4. Preheat Oven: Preheat oven to 350°F (175°C). Grease a loaf pan.

5. Bake: Pour the batter into the prepared pan and bake for 50-60 minutes, or until a toothpick inserted into the center comes out clean.
