Grease a metal loaf pan or line it with parchment paper. (See note about pan size.)
Whisk the dry ingredients together in a large bowl.
Add the wet ingredients and mix well. A stand mixer works great for this. If you don't have a stand mixer (The batter is probably too thick for a hand mixer.), whisk the wet ingredients together and then mix them well into the dry ingredients. Batter will be very moist.
Scrape batter into prepared pan. Allow to rise in a warm place for an hour.
