Preheat your oven to 350°F (175°C) and prepare two standard loaf pans with nonstick spray and parchment paper.

In a medium bowl, whisk together all-purpose flour, baking soda, ground ginger, ground cinnamon, ground cloves, and kosher salt.

In a stand mixer, combine brown sugar and unsulfured blackstrap molasses and mix on low for 1-2 minutes.

Drizzle in the vegetable oil while mixing on low speed until fully integrated.

Add eggs to the mixture and mix until everything is combined and shiny.

Gradually fold in the dry ingredients in two additions and mix until just combined.

Slowly add boiling water while mixing on low, creating a thin batter.

Gently fold in the grated lemon zest to enhance flavor.

Divide the batter between the loaf pans and bake for about 1 hour.

Allow the loaves to cool in the pans for about 10 minutes before transferring to a wire rack.
