Step 1

To make the cake, preheat the oven to 350 degrees Fahrenheit. Grease a 9x13-inch cake pan with oil or butter.

Step 2

In a large bowl, stir together the sugar, flour, eggs, baking soda, vanilla, and pineapple until well-combined.

Step 3

Pour the batter into greased pan. Bake for 35 to 40 minutes. Transfer onto a wire rack and set aside.

Step 4

Meanwhile, prepare the icing. In a large saucepan over medium heat, combine the butter, sugar, and evaporated milk and bring to a boil, stirring constantly. Cook and stir for another 5 minutes, or until the mixture is thick.

Step 5

Remove the pan from heat and stir in the coconut, nuts, and vanilla.

Step 6

Poke holes in the cake with a skewer and pour the mixture over. Slice and enjoy!
