Step 1: Preheat Oven & Prep Workspace Preheat oven to 350°F (175°C) and line a 9×13-inch baking pan with parchment paper with an overhang. Whisk flour, brown sugar, granulated sugar, and salt; cut in cold cubed butter until coarse crumbs form. Reserve 1 cup of crumb mixture and toss with rolled oats for the topping.
Step 2: Bake to Golden Perfection Press the remaining mixture firmly into the bottom of the prepared pan. Pre-bake the shortbread crust for 12-15 minutes until lightly golden. In a bowl, toss the fruit with sugar, cornstarch, lemon juice, and spices.
Step 3: Cool Completely on Wire Rack Spread spiced fruit layer evenly over the warm crust, then scatter reserved oat streusel topping on top. Bake at 350°F (175°C) for 30-35 minutes until the fruit is bubbling and the streusel topping is deeply golden. Cool completely on a wire rack before lifting out and slicing into neat bakery bars with a sharp chef knife. Serve slightly warm or at room temperature alongside a generous scoop of artisanal vanilla bean ice cream, a dollop of fresh whipped cream, or a steaming cup of freshly brewed dark roast coffee. Store leftovers in an airtight container in the refrigerator for up to 4-5 days. Reheat gently to preserve delicate flavors and textures. • **Room Temperature Ingredients:** Bringing dairy and eggs to room temperature creates smooth, cohesive batters that rise evenly. • **Accurate Flour Measuring:** Spoon flour into measuring cups and level with a knife to avoid dense, heavy baked goods. • **Cool Before Slicing:** Let pastries cool completely so internal steam redistributes and textures set cleanly. • **Berry & Fruit Swirl:** Fold in fresh raspberries, wild blueberries, or sliced bananas for juicy bursts of natural sweetness. • **Warm Spice Accent:** Add a pinch of cinnamon, freshly grated nutmeg, or pure vanilla bean paste for kitchen-fresh warmth.
