Step 1

Preheat your oven to 180°C (350°F) and get a 1-quart pie dish or pan.

Step 2

Place the blueberries in the pie pan, and sprinkle with potato flour.

Step 3

Mix and move the blueberries around to distribute the potato flour evenly.

Step 4

Prepare the oatmeal crumble topping by combining the flour, chilled butter, salt, sugar, and rolled oats in a food processor.

Step 5

Pulse until you see big chunks of dough forming.

Step 6

Use your hands to break the dough into a crumble and add them to the blueberries.

Step 7

Place your blueberry pie with crumble topping in the oven for 20 to 25 minutes or until it turns golden.

Step 8

Take it out of the oven --- you will typically see the sides still bubbling with blueberry juices at this point.

Step 9

Set aside for a few minutes to cool.

Step 10

Serve your Swedish blueberry crumble with vanilla sauce or a scoop of ice cream --- enjoy!
