Step-by-Step Instructions
  1. Preheat your oven to 350°F (175°C) and line an 8x8-inch baking pan with parchment paper.
  2. Melt ½ cup of unsalted butter in a microwave-safe bowl until completely liquid, then allow it to cool slightly.
  3. Whisk together the melted butter, 1 cup of granulated sugar, 1 large egg, and 1 teaspoon of vanilla extract until smooth.
  4. Fold in 1 cup of all-purpose flour, ½ teaspoon of salt, and the zest of one lemon until just incorporated.
  5. Gently fold in 1 cup of fresh blueberries until evenly distributed.
  6. Pour the batter into the prepared pan and bake for 25–30 minutes, or until the edges are golden.
  7. Cool in the pan for 10-15 minutes before removing with the parchment overhang.
  8. Whisk together 1 cup of powdered sugar and 2 tablespoons of fresh lemon juice until smooth for the glaze.
  9. Drizzle the glaze over the cooled blondies and let it set before slicing into squares.
