Ingredients:

  • 1 cup (225g) unsalted butter, softened to room temperature
  • 1 ½ cups (300g) granulated sugar
  • 1 large (50g) egg, room temperature
  • 2 tsp (10ml) pure vanilla extract
  • 2 ¾ cups (340g) all-purpose flour
  • 1 tsp (5g) baking powder
  • ½ tsp (3g) salt
  • 2 cups (240g) powdered sugar, sifted
  • 3 tbsp (45ml) heavy cream
  • ¼ cup (60ml) blended berry puree
  • ½ tsp (2.5ml) lemon juice
  • 1 cup (150g) fresh blueberries
  • 1 cup (150g) fresh sliced strawberries

Instructions:

  1. Preheat oven to 350°F (175°C) and line a 9x13 inch baking pan with parchment paper.
  2. Cream the softened butter and granulated sugar on medium-high speed for 3 minutes until the mixture is pale yellow and fluffy.
  3. Beat in the room temperature egg and vanilla extract until fully incorporated.
  4. In a separate bowl, whisk together the flour, baking powder, and salt; gradually add this to the wet ingredients on low speed just until no white streaks remain.
  5. Press the dough evenly into the prepared pan using your hands or an offset spatula.
  6. Bake for 15-18 minutes until the edges just begin turning a pale gold and the center feels springy but not firm.
  7. Remove from the oven and allow the bars to cool completely in the pan to ensure the glaze sets properly.
  8. Whisk together the powdered sugar, heavy cream, berry puree, and lemon juice until the glaze is smooth and flows slowly.
  9. Pour the glaze over the cooled bars and garnish with fresh blueberries and sliced strawberries.
