Ingredients
Scale
- 1 cup all-purpose flour
- 1/2 cup (1 stick) cold unsalted butter, cubed
- 1/4 cup granulated sugar
- 1/2 cup shelled pistachios, roughly chopped and divided
- 1/2 cup high-quality blackberry preserves or jam
- 1 cup white chocolate chips
- 2 large eggs, lightly beaten
- 1/2 teaspoon pure alcohol-free vanilla extract
Instructions
- Step 1: Preheat the oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, leaving an overhang on two sides. In a medium bowl, combine the flour, sugar, and half (1/4 cup) of the chopped pistachios. Cut in the cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs. Press the mixture firmly and evenly into the prepared pan.
- Step 2: Bake the crust for 15 minutes, or until the edges are light golden brown. While the crust is baking, melt the white chocolate chips either in a microwave in 30-second intervals or in a double boiler until smooth.
- Step 3: Remove the par-baked crust from the oven. Gently and evenly spread the blackberry preserves over the hot crust. In a separate bowl, whisk together the melted white chocolate, the beaten eggs, and the alcohol-free vanilla extract until fully incorporated.
- Step 4: Pour the chocolate-egg mixture over the layer of blackberry preserves. Sprinkle the top evenly with the remaining 1/4 cup of chopped pistachios.
- Step 5: Return the bars to the oven and bake for an additional 20 to 25 minutes, or until the edges are set and the center is firm to the touch. Let the bars cool completely at room temperature for at least 2 hours before lifting them out of the pan using the parchment paper overhang. Cut into 16 squares to serve.
Notes
- Keep any leftovers stored tightly wrapped in the refrigerator for up to five days, but always let them sit at room temperature for 15 minutes before enjoying for optimal texture.
- These bars are best served chilled or at room temperature, so avoid microwaving or heating them, which could cause the creamy topping to separate or melt away from the crust.
- For an elevated experience, serve the bars with a spoonful of crème fraîche or a small scoop of pistachio gelato to highlight the fruity tartness and nutty base.
- For the sharpest slices and clean layers, chill the fully cooled bars in the refrigerator for 30 minutes before using a sharp, non-serrated knife dipped in hot water to cut them.
