Step‑by‑Step Instructions
- Preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper.
- In a bowl, combine the all-purpose flour, powdered sugar, and salt. Whisk them together until evenly blended.
- Cut in the cold, cubed unsalted butter into the flour mixture until it resembles coarse crumbs.
- Add vanilla extract and mix until just combined. Press 1/3 of the mixture firmly into the baking pan.
- Gently toss blackberries with granulated sugar, cornstarch, and lemon zest. Let sit for a few minutes.
- Spread the blackberry mixture evenly over the shortbread base and sprinkle the reserved crumbs on top.
- Brush the top with heavy cream and sprinkle with coarse sugar.
- Bake for 25 to 30 minutes until edges are golden brown and filling is bubbly.
- Let cool completely before slicing into wedges.
- Serve at room temperature or slightly warm.
