Blackberry Pistachio Dream Bars

Delightful dessert bars featuring a buttery base, tart blackberries, and crunchy pistachios, perfect for any occasion.

Ingredients

  • 2 cups Blackberries, fresh or thawed if using frozen
  • 1 large Egg
  • 1 large Egg yolk
  • 1 tbsp Lemon juice
  • 1 cup All-purpose flour (or gluten-free flour)
  • 1 tsp Baking powder
  • 1/2 cup Brown sugar, light
  • 2 tbsp Cornstarch
  • 3/4 cup Granulated sugar
  • 1/4 tsp Salt
  • 1 tsp Vanilla extract
  • 1 cup Pistachios, chopped (or almonds/walnuts)
  • 2 tbsp Ice water
  • 1 cup Butter, unsalted (or plant-based butter)

Instructions

  1. Preheat the oven to 350°F (175°C). Grease and line a baking pan with parchment paper.
  2. Beat the butter with the brown and granulated sugars until light and fluffy, about 2–3 minutes.
  3. Add the egg, egg yolk, lemon juice, and vanilla; mix until glossy and homogenous.
  4. In a separate bowl, whisk together the flour, baking powder, cornstarch, and salt.
  5. Gradually add the dry ingredients to the wet mixture, folding gently until just combined.
  6. Gently fold in the blackberries and chopped pistachios.
  7. Pour the batter into the prepared pan and smooth the top with a spatula.
  8. Bake for 25–30 minutes until golden and a toothpick comes out mostly clean.
  9. Cool completely on a wire rack before cutting into squares.

Notes

If using frozen blackberries, do not thaw completely. Chopped pistachios can be lightly toasted for extra flavor.
