How to Make Berry Streusel Bars
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C). Line a baking pan with parchment paper, leaving overhang for easy removal.
Step 2: Make the Crust & Streusel
In a large bowl, mix flour, sugars, and salt. Cut in cold butter until the mixture resembles coarse crumbs. Press about two-thirds of the mixture firmly into the bottom of the pan to form the crust.
Step 3: Prepare the Berry Filling
In another bowl, gently toss berries with sugar, cornstarch, lemon juice, and vanilla until evenly coated.
Step 4: Assemble
Spread the berry mixture evenly over the crust. Sprinkle the remaining crumb mixture over the top.
Step 5: Bake
Bake for 40–45 minutes, or until the topping is golden and the berry filling is bubbling around the edges.
Step 6: Cool and Slice
Allow bars to cool completely before slicing. This helps them set cleanly and hold their shape.
