Fire up your oven to 350°F and get a 9x13 pan ready with parchment paper, leaving a bit extra on the sides so you can easily lift everything out later.

Combine the flour, sugar, and salt in a bowl. Toss in the cold butter cubes, and use your hands or a fork to blend until you have a crumbly texture. Press this mix firmly into your pan to form an even layer.

Put your pan in the hot oven and bake for roughly 15 minutes, until the sides look just barely golden. Take it out to cool while you whip up the next layer.

In another bowl, beat the eggs and sugar together until smooth. Add the flour, vanilla, and baking powder, stirring well. Fold in the pineapple at the end – make sure there's no extra juice, or it won't set properly.

Spread the pineapple mix over the slightly cooled crust. Return the pan to the oven and bake for 25-30 minutes, until the edges are firm but the center still has a slight wobble when shaken lightly.

Let the bars chill completely in the pan before taking them out. Once cooled, sprinkle powdered sugar all over. Use the parchment to lift the bars out, and cut them into squares on a board.
