Preheat oven to 350°F. Coat a 9×5 loaf pan with nonstick spray. Line the bottom and up the ends with a strip of parchment paper for easy removal. Coat again with nonstick spray. Set aside.

Step 2

In a large bowl whisk together flour, baking powder, baking soda, and salt.

Step 4

Add the wet ingredients into the dry ingredients and stir until just combined.

Step 5

Pour the batter into the prepared pan.

Step 6

Bake for 55-65 minutes, or until a toothpick inserted into the center comes out clean.

Step 7

Allow to cool 10 minutes in the pan and then transfer to a wire rack to cool completely.
