Spray a standard 9x5 loaf pan and line it with a sheet of parchment paper, leaving the ends to hang long. This way you can lift the cake bread for cleaner cutting.
In a large mixing bowl whisk together the wet ingredients.
Whisk in the salt, cocoa powder, salt, and baking soda. Switch to a silicone spoonula and fold in the flour. When you've got the flour almost completely incorporated, fold in the nuts. Blend just until there is no dry flour remaining, but don't over mix your batter.
Turn the batter into the prepared loaf pan, it is a thin batter. Top with the finely chopped walnuts.
Bake in your preheated oven for 45-50 minutes, until a toothpick inserted in the center comes out without wet batter clinging to it. Fudgy crumbs are fine. Check your cake on the early side to avoid over-baking. Set aside to cool.
If you have used a parchment paper 'sling', gently pull the cake out of the pan to slice it. You can slice and serve while still warm if you like, or let the bread cool, it's your choice. I use a sharp serrated bread knife and a gentle sawing motion to avoid crushing the bread. Don't slice until ready to enjoy or the bread will start to dry out.
Keep leftovers in an airtight container or under foil at room temperature. The bread can be frozen for longer storage.*
Notes
*To freeze first let the bread cool completely, then wrap in plastic, then in foil. Or place in a sturdy zip lock freezer bag and push out any extra air before zipping.Be sure to check the post for more details, tips, and helpful photos!
