Preheat your oven to 350°F (175°C) and prepare your loaf pan by greasing it lightly.

In a large bowl, whisk together the all-purpose flour, granulated sugar, instant pistachio pudding mix, baking powder, and salt until well combined.

In a separate bowl, mix the eggs, milk, vegetable oil, and vanilla extract until smooth and creamy.

Gently fold the wet ingredients into the dry mixture, stirring just until combined.

Pour the batter into your prepared loaf pan and bake for 50-55 minutes, or until a toothpick inserted in the center comes out clean.

Optional: Top with a sprinkle of chopped pistachios for extra crunch and color.
