Preheat your oven to 350°F (175°C) and take out a 9x13-inch baking dish. Grease the dish lightly to prevent sticking.

Open the cans of crushed pineapple and pour them into the baking dish, making sure to include all the juice. If you prefer, you can use pineapple chunks instead.

Next, grab your box of yellow cake mix. Evenly sprinkle the cake mix over the layer of crushed pineapple in the baking dish. Remember, if you don't have yellow cake mix on hand, you can also use white or spice cake mix.

If you're opting for a bit of extra crunch and flavor, now's the time to add the chopped pecans. Scatter them evenly over the cake mix layer.

Now, for a touch of sweetness and caramelization, sprinkle the brown sugar evenly over the top of the pecans.

It's time to add that indulgent touch of melted butter. Drizzle the melted butter evenly over the entire surface of the cake mix.

With all the ingredients in place, it's time to pop your creation into the preheated oven. Bake for about 45 to 50 minutes, or until the top turns a beautiful golden brown and the edges start to bubble.

Once baked to perfection, take the cake out of the oven and allow it to cool for at least 20 minutes before serving.

When you're ready to eat, slice up your Pineapple Dump Cake and serve it warm. If you're feeling extra indulgent, top it off with a scoop of vanilla ice cream or a dollop of whipped cream.

Enjoy the deliciousness of your homemade Pineapple Dump Cake Recipe.
