Ingredients
Scale
Pie Dough
- 1 cup unsalted butter (frozen)
- 2 1/2 cups all-purpose flour
- 1/4 cup granulated sugar
- 1 teaspoon fine sea salt
- 1 teaspoon vanilla paste
- 7–10 tablespoons ice water
Blueberry Pie Filling
- 2 1/2 cups frozen blueberries
- 1/4 cup brown sugar (packed)
- 1 teaspoon lemon juice
- 1 tablespoon cornstarch
- 1 tablespoon water
For Assembly
- 1 egg (lightly beaten)
- Turbinado sugar (for sprinkling)
Instructions
- Prepare Butter: Line a sheet tray with parchment paper or a silicone mat, grate the frozen butter sticks onto the tray, and keep them in the freezer until ready to use.
- Line Baking Pan: Line an 8×8-inch metal baking pan with parchment paper, covering all four sides; set aside.
- Mix Dry Ingredients: In a stand mixer bowl, whisk together flour, sugar, and salt to combine evenly.
- Add Butter to Flour: Add grated frozen butter to the flour mixture and mix on low speed until butter pieces are coated in flour and resemble pea-sized crumbs.
- Incorporate Vanilla and Water: Add vanilla paste. With the mixer running on low, drizzle in 7-10 tablespoons of ice water gradually until the dough starts to clump together.
- Divide and Chill Dough: Separate the dough into two equal parts (about 366 grams each). Press one half into a slab, wrap tightly in plastic wrap, and press the other half evenly into the bottom of the lined pan. Refrigerate both for 30 minutes. Meanwhile, preheat oven to 375°F (190°C) and prepare the filling.
- Make Blueberry Filling: Combine blueberries, brown sugar, and lemon juice in a pot. Cook over medium heat, stirring occasionally, until blueberries release juices and mixture boils. Mix cornstarch and water and stir into filling. Cook 1-2 more minutes until thickened. Set aside.
- Bake Bottom Crust: Remove bottom crust from fridge and bake 25-35 minutes until edges turn golden brown.
- Prepare Lattice Top: While bottom crust bakes, roll out the second slab of dough on a lightly floured surface into a 9×9-inch square. Cut into 1/2-inch strips.
- Weave Lattice: Lay 8 strips parallel on a parchment-lined baking sheet, spaced evenly. Fold back every other strip, lay one strip perpendicular across, then unfold. Alternate folding the opposite strips and laying perpendicular strips until a 9×9-inch lattice square forms.
- Trim and Freeze Lattice: Trim lattice edges to roughly 7.5×7.5 inches for clean edges and freeze until firm enough to lift as a single piece.
- Assemble Bars: Once bottom crust is baked and lattice is firm, spread blueberry filling evenly over crust, then transfer lattice on top.
- Apply Egg Wash and Sugar: Brush lattice with beaten egg and sprinkle turbinado sugar on top.
- Bake Bars: Bake for 25-30 minutes or until the lattice crust is golden brown.
- Cool and Serve: Let bars cool completely on a wire rack for 1-2 hours. Cut into 16 small bars or 6-8 larger bars and enjoy.
Notes
- Use frozen butter grated to keep the dough flaky and tender.
- Measure flour correctly by spooning into the cup and leveling off with a knife to avoid excess flour and dense crust.
- Keep dough chilled before baking to ensure a crisp, flaky crust and easier handling.
- Using turbinado sugar adds a subtle crunch and natural sweetness to the lattice crust.
- If fresh blueberries are used instead of frozen, reduce lemon juice slightly and monitor filling thickness.
