Step-by-Step Instructions

Prepare the Oven and Pan

Preheat your oven to 350 degrees Fahrenheit. Line an 8×8 inch baking pan with parchment paper, leaving extra on the sides for easy lifting later.

Make the Crumble Mixture

In a bowl, mix flour, sugar, and salt. Add softened butter and mix until crumbly. The mixture should look like soft crumbs and hold together when pressed.

Divide the Crumble

Measure out about 1/4 of the crumble mixture and set it aside. This part will be used as the base. Keep the remaining 3/4 for the crumble topping.

Bake the Base Layer

Press the 1/4 portion of crumble firmly into the bottom of the pan to form a thin, even base. Bake for about 10 to 12 minutes until lightly set. It does not need to be very golden.

Make the Pineapple Filling

In another bowl, mix sugar and flour. Add the egg, sour cream, and vanilla extract. Whisk until smooth and creamy with no lumps.

Add the Pineapple

Fold in the drained pineapple chunks. Make sure they are evenly spread in the mixture so each bite has fruit.

Assemble the Bars

Pour the pineapple filling over the warm base. Spread evenly with a spatula.

Now take the remaining 3/4 crumble mixture and sprinkle it evenly over the top. Do not press it down. This creates the crumbly topping.

Bake Until Golden

Bake for 30 to 35 minutes. The top should look lightly golden and the filling should be set.

Cool and Slice

Let the bars cool completely in the pan. This helps them firm up.

Lift out using parchment paper, place on a board, and slice into squares. Your pineapple crumble bars are ready to serve.
