- Preheat the Oven 
- Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish or line it with parchment paper. 
- Mix the Cake Batter 
- In a large mixing bowl, combine the flour, sugar, and baking soda. Add the eggs, vanilla extract, and undrained crushed pineapple. Mix until well combined. Fold in the chopped pecans. 
- Bake the Cake 
- Pour the batter into the prepared baking dish. Bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool completely in the pan. 
- Prepare the Frosting 
- In a separate bowl, beat the softened cream cheese and butter together until smooth and creamy. Gradually add the powdered sugar and vanilla extract, mixing until fully combined. 
- Frost the Cake 
- Spread the frosting evenly over the cooled cake. Sprinkle the top with additional chopped pecans, if desired. 
- Serve and Enjoy 
- Slice into squares and serve. Refrigerate leftovers to keep the frosting fresh.
