Preheat oven to 350°F. Prepare an 8x8 baking pan with nonstick spray or parchment paper.
In a large bowl, gently whisk flour, ginger, baking soda, baking powder, cinnamon, and salt.
In a separate medium bowl, whisk together applesauce, buttermilk, brown sugar, canola oil, molasses, and eggs.
Add buttermilk mixture to flour mixture. Using a spatula, fold ingredients until just moistened. Do not overmix.
Pour batter into the prepared baking pan. Cook 25-30 minutes, or until a toothpick inserted comes out clean. Enjoy!
