Preheat Oven:
Preheat your oven to 350°F (175°C) and lightly grease a 9x13-inch baking pan.
Mix Dry Ingredients:
In a large mixing bowl, whisk together the flour, sugar, baking soda, and salt.
Combine Wet Ingredients:
In a separate bowl, mix the eggs, vanilla extract, and crushed pineapple (including the juice).
Create the Batter:
Gradually add the wet ingredients to the dry ingredients, mixing gently until just combined. Be careful not to overmix.
Bake the Cake:
Pour the batter into the prepared pan and spread evenly. Bake for 30–35 minutes or until a toothpick inserted in the center comes out clean. Remove from the oven and let the cake cool on a cooling rack.
Prepare the Pineapple Glaze:
In a small saucepan, combine powdered sugar, pineapple juice, melted butter, and vanilla extract. Heat over low heat, stirring until smooth and well combined.
Glaze the Cake:
Once the cake has cooled slightly, poke holes all over the surface with a fork or skewer. Pour the warm pineapple glaze evenly over the cake, letting it soak into the holes.
Cool and Serve:
Allow the cake to cool completely before slicing and serving.
