Preheat your oven to 350°F (175°C). Grease a loaf pan.
In a mixing bowl, combine flour, sugar, baking powder, baking soda, and salt.
Stir in chopped pistachios.
In another bowl, whisk together milk, vegetable oil, eggs, and vanilla extract.
Pour the wet ingredients into the dry ingredients and mix until just combined.
Pour the batter into the prepared loaf pan.
Bake for 50 minutes or until a toothpick inserted into the center comes out clean.
Let the bread cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
