Prep: Preheat your oven to 350°F (175°C). Grease a 9x5-inch loaf pan thoroughly.
Sift: In a medium bowl, sift together the flour, baking powder, and salt. This ensures your bread rises evenly without any lumps.
Cream: In a separate large bowl, beat the softened butter and granulated sugar together until the mixture is pale and smooth.
Emulsify: Add the eggs one at a time, beating well after each addition.
Combine: Gradually alternate adding the sifted dry ingredients and the ¼ cup of pineapple liquid into the butter mixture. Stir until just integrated to avoid overworking the gluten.
Final Fold: Stir in the milk, then delicately fold in the crushed pineapple pieces using a spatula.
Bake: Pour the batter into the prepared loaf pan and smooth the top. Bake for 50–55 minutes. Test the center with a skewer—it should come out clean.
Cool: Let the loaf rest in the pan for 10–15 minutes, then move to a wire rack. The bread must be completely cool before glazing.
Glaze: Whisk the confectioners' sugar, 2 tbsp juice, and vanilla until smooth. Drizzle over the cooled bread and let it set before slicing.
