Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan with cooking spray or butter.
2. Mix the Ingredients
In a large mixing bowl, combine the undrained crushed pineapple, yellow cake mix, eggs, vegetable oil, and vanilla extract.
Using a whisk or an electric mixer, mix until well combined and the batter is smooth.
3. Pour into the Pan
Pour the batter into the prepared baking pan, spreading it evenly.
4. Bake the Cake
Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted in the center comes out clean. The top should be lightly golden.
5. Cool the Cake
Remove the cake from the oven and let it cool in the pan on a wire rack for about 10-15 minutes.
Once cooled, you can frost it or serve it plain. If desired, dust the top with powdered sugar or serve with whipped cream.
Notes and Tips
Add a Frosting: For an extra layer of sweetness, consider frosting your cake with cream cheese frosting or a light vanilla frosting. The tangy cream cheese pairs wonderfully with the pineapple flavor.
Mix-Ins: You can add shredded coconut or chopped nuts (like walnuts or pecans) to the batter for added texture and flavor.
Make It a Pineapple Upside-Down Cake: For a twist, pour a little melted butter in the bottom of the pan, sprinkle brown sugar, and arrange pineapple slices before adding the batter on top. Bake as directed, then invert to serve!
