Combine the dates and boiling water in a small bowl and let stand for 15 minutes.
Meanwhile, combine the dry ingredients in a separate mixing bowl.
Add remaining wet ingredients to the date mixture and add that to dry ingredients.
Stir just to combine and fold in the walnuts.
Pour into a non-stick 9 x 5-inch loaf pan coated with cooking spray (or lined with parchment paper) and bake for 40-45 minutes, until a toothpick inserted in the center comes out clean.
Let cool completely on a cooling rack before slicing.
