Step-by-Step Instructions
Prepare the Baking Pan Properly
Preheat your oven to 350°F (175°C). Take a square baking pan and line it with parchment paper. Make sure the paper hangs slightly over the edges so you can lift the bars out later. Press the paper gently into the corners so it sits flat. This step helps prevent sticking and makes clean slices easier.
Mix the Dry Ingredients Thoroughly
In a large mixing bowl, add the flour, rolled oats, brown sugar, salt, and baking powder. Stir everything together slowly using a spoon or spatula. Make sure the ingredients are evenly combined and there are no lumps of sugar left. This will help the crumble bake evenly.
Add Melted Butter and Form Crumble
Pour the melted butter into the dry mixture. Mix slowly until the texture becomes crumbly. Some parts should form small clumps while others stay loose. Do not overmix. The mixture should look slightly uneven and sandy with small chunks.
Press the Base Layer Firmly
Take about half of the crumble mixture and place it into the lined baking pan. Spread it out gently, then press it down firmly using your hands or the back of a spoon. Make sure the layer is even across the bottom, but it does not need to be perfect. Pressing well helps the base hold together after baking.
Prepare the Pineapple Filling
In another bowl, add the crushed pineapple, sugar, cornstarch, and vanilla extract. Stir until everything is fully combined. The mixture should look slightly thick and glossy. Make sure there are no dry pockets of cornstarch left.
Spread the Filling Evenly
Pour the pineapple mixture over the pressed base layer. Use a spoon or spatula to spread it across the surface. Try to cover the base fully, but it is fine if it is not perfectly smooth. Keep the layer even so it bakes properly.
Add the Crumble Topping
Take the remaining crumble mixture and sprinkle it over the pineapple filling. Drop it in small clumps across the top. Do not press it down. The uneven topping creates a nice crumbly texture after baking.
Bake Until Golden and Set
Place the pan in the oven and bake for 30 to 35 minutes. The top should turn light golden brown. The edges may look slightly darker and crisp. The filling should look set and not too wet.
Cool Completely Before Cutting
Remove the pan from the oven and let it cool completely at room temperature. This step is very important. If you cut the bars too early, they may fall apart. Once cooled, lift the bars out using the parchment paper and slice into squares.

- Always drain pineapple well to avoid extra moisture
