To begin, preheat the oven to 350 degrees and apply a layer of grease on a loaf pan measuring 9 inches by 5 inches. It is worth mentioning that using parchment paper with tall sides can also facilitate the easy removal of the loaf from the pan.
Combine all-purpose flour, baking soda, and sea salt in a medium-sized bowl and mix until well blended.
Using a stand mixer, combine sugar and butter with the paddle attachment, operating at a low-medium speed, for approximately 5 minutes.
Next, include the eggs and vanilla extract, then continue mixing for an additional minute using the lowest setting.
Carefully pour the flour mixture into the bowl, making sure to use a spatula to lift the bottom of the bowl and blend all the ingredients together evenly.
Combine the drained crushed pineapple and mix it gently until well blended; you can accomplish this by using a spatula manually.
Pour into greased pan and spread evenly.
Bake for about 55 minutes.
Allow the loaf to cool completely in the pan on a wire rack before taking it out.
After the loaf has cooled down, take it out of the pan. To prepare the glaze, combine powdered sugar and pineapple juice in a small bowl and mix thoroughly.
