🧾 Ingredients
🧈 For the Crust & Crumb Topping:
- 2 ½ cups all-purpose flour
- 1 cup granulated sugar
- 1 cup unsalted butter, cold and cubed
- ½ teaspoon salt
- 1 teaspoon vanilla extract
🫐 For the Blueberry Filling:
- 3 cups fresh or frozen blueberries
- ½ cup granulated sugar
- 2 tablespoons cornstarch
- 1 tablespoon lemon juice
- 1 teaspoon lemon zest
- ½ teaspoon cinnamon (optional, but lovely)
👩🍳 Instructions
1️⃣ Prepare the Oven & Pan
- Preheat oven to 180°C (350°F).
- Line a 9×13-inch baking pan with parchment paper.
2️⃣ Make the Crumb Mixture
- In a large bowl, mix flour, sugar, and salt.
- Cut in cold butter using your hands or a pastry cutter until crumbly.
- Stir in vanilla extract.
- The mixture should resemble coarse crumbs.
3️⃣ Form the Base
- Press about 2/3 of the mixture firmly into the bottom of the pan.
- Bake for 10–12 minutes until lightly golden.
4️⃣ Prepare the Filling
- In another bowl, combine blueberries, sugar, cornstarch, lemon juice, zest, and cinnamon.
- Mix gently until coated.
5️⃣ Assemble the Bars
- Spread the blueberry mixture evenly over the warm crust.
- Sprinkle the remaining crumb mixture on top.
6️⃣ Bake
- Bake for 40–45 minutes, until the top is golden and the filling is bubbling.
7️⃣ Cool & Slice
- Let cool completely before cutting into bars (this helps them set properly).
🍰 Methods & Tips for Success
- Cold butter is key: It creates that perfect crumbly texture.
- Don’t skip the pre-bake: It prevents a soggy base.
- Use cornstarch: This thickens the filling beautifully.
- Fresh vs frozen blueberries: Both work! If frozen, don’t thaw first.
- Chill before slicing: For clean, bakery-style squares.
📜 History & Origin
Crumb bars are inspired by European streusel-topped desserts, especially from German and Eastern European baking traditions. Over time, they evolved into easy tray bakes in American kitchens, where fruits like blueberries became a favorite filling due to their natural sweetness and availability.
🧩 Formation (How It Comes Together)
- Layer 1: Firm, buttery crust
- Layer 2: Juicy blueberry filling
- Layer 3: Crisp golden crumble
This triple-layer structure creates a contrast of textures: soft, juicy, and crunchy—all in one bite.
