### Instructions
1. **Preheat Oven & Prep Dish:** Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish.
2. **Pineapple Layer:** Pour the undrained crushed pineapple evenly into the bottom of the prepared baking dish.
3. **Cake Mix Layer:** Evenly sprinkle the dry yellow cake mix over the pineapple layer. Do not mix!
4. **Sugar Sprinkle:** Sprinkle the granulated sugar evenly over the cake mix.
5. **Melted Butter Drizzle:** Drizzle the melted butter evenly over the top of the sugar and cake mix.
6. **Coconut (Optional):** If using, sprinkle the shredded coconut over the top.
7. **Bake:** Bake for 25-30 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.
8. **Cool & Serve:** Let cool for a few minutes before serving. Enjoy warm, or at room temperature!
### Short Tips
* **Serve it warm with a scoop of vanilla ice cream** for an extra special treat.
* **For a slightly tangier flavor**, use a smaller amount of the cake mix (around 3/4 of the box) to let the pineapple shine through more.
* **Storage:** Leftovers (if there are any!) can be stored covered in the refrigerator for up to 3 days. Reheat gently in the microwave or oven.
* **Gluten-Free Option:** Use a gluten-free yellow cake mix for a delicious GF version that everyone can enjoy!
