Preheat the oven to 350°F (175°C) and grease a bundt pan.
In a large bowl, whisk together the flour, sugar, baking powder, and salt.
Add the vegetable oil, eggs, pineapple juice, and vanilla extract. Mix until smooth.
Pour the batter into the prepared bundt pan and bake for 40-45 minutes, or until a toothpick inserted comes out clean.
Allow the cake to cool before removing it from the pan.
Optional: Drizzle with a pineapple glaze before serving.
