Instructions:

Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish or a similar-sized casserole dish with cooking spray or butter.
Prepare the Batter: In a large bowl, cream together the softened butter and granulated sugar until light and fluffy. Add the eggs one at a time, beating well after each addition. Stir in the drained crushed pineapple and vanilla extract.
Mix Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Assemble the Bake: Spread the batter evenly into the prepared baking dish. If using shredded coconut, sprinkle it evenly over the top of the batter.
Prepare Topping: In a small bowl, mix together the brown sugar and chopped pecans. Sprinkle this mixture evenly over the top of the batter.
Bake: Bake in the preheated oven for 40-45 minutes, or until a toothpick inserted into the center comes out clean and the top is golden brown.
Cool and Serve: Allow the pineapple bake to cool for at least 10 minutes before serving. Cut into squares and serve warm or at room temperature.
