This Swedish Blueberry pie is a pie without a crust, topped instead with a thick cake like crumble, by placing slices of frozen dough on top of the blueberry filling and baking it until brown and bubbling.
For the Crust: In a large bowl, add softened butter and sugar and stir to combine.
Add vanilla extract and eggs and stir to combine. Add in the flour and salt and combine.
Shape the dough into a log, wrap with plastic wrap, and place in the freezer until hardened, about an hour or overnight. Placing it in the freezer will make for a crispier crust.
Preheat the oven to 350°F.
For the Filling: Place the blueberries in a ceramic square baking dish (pie dish works too). Add the sugar, flour, cinnamon, and salt. Stir to combine.
Take the dough out of the freezer and cut into slices. Layer the slices on top, covering the blueberry filling and overlapping in places if needed.
Bake in the oven at 350°F for 1 hour or until golden brown on top and the blueberry filling is bubbling.
Serve warm with vanilla ice cream.
Notes
Butter: If you have not softened your butter ahead of time, place it in the mixing bowl and microwave it at 20% power for 30 seconds, flipping it over and repeating until softened.
Blueberries: Use fresh blueberries. The fresher the better. I do not recommend using frozen strawberries because of the difference in the water content and texture.
Cinnamon: If possible, use high-quality cinnamon. Poor quality cinnamon can leave a really bad taste. Usinghigh-quality cinnamon makes a really big difference. I use Ceylon Cinnamon from a brand called Simply Organic, which can be found at Whole Foods and some specialty retailers.
