Preheat your oven to 350°F (175°C).
In a large mixing bowl, combine the all-purpose flour, baking soda, and salt.
In another bowl, mix together the granulated sugar, eggs, and vanilla extract until well combined.
Stir in the undrained crushed pineapple into the sugar mixture.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Pour the batter into a greased baking pan.
Bake in the preheated oven for about 30-35 minutes, or until a toothpick inserted in the center comes out clean.
Allow the cake to cool before serving.
