Preheat oven to 350°F.
Grease a 9x13 pan and set aside.
Whisk together flour, sugars, and baking soda in a large bowl.
Stir in eggs, vanilla extract, and pineapple (including the juice) until mixed well.
Pour the batter into the prepared pan.
Bake for 28-30 minutes or until a toothpick inserted in the center of the cake comes out clean or with just a few crumbs attached, but not raw batter. Do not overcook.
Cool the cake completely, top it with cream cheese frosting or whipped cream, and garnish it with pineapple bits.
