Ingredients

Scale

Blondie Base

  • 3/4 cup unsalted butter, softened
  • 1 cup granulated sugar
  • 1/4 cup light brown sugar
  • 2 large eggs
  • 1/2 teaspoon salt
  • 1/4 teaspoon baking powder
  • Zest of 1 lemon
  • 1 1/4 cups all purpose flour

Lemon Curd

  • 1/4 cup lemon curd

Instructions

  1. Preheat and prepare pan: Preheat the oven to 350°F (175°C). Line an 8×8 inch square baking pan with parchment paper, leaving overhang on all sides for easy removal later.
  2. Cream butter and sugars: In a large bowl or using a stand mixer, beat the softened butter together with granulated sugar and light brown sugar until light and fluffy, creating a smooth and aerated base for the blondies.
  3. Add eggs: Incorporate the eggs one at a time into the butter and sugar mixture, mixing well after each addition. Scrape down the bowl as needed to ensure even mixing.
  4. Mix dry ingredients and lemon zest: Add salt, baking powder, and lemon zest to the batter. Stir to combine evenly, enhancing the flavor with bright citrus notes.
  5. Incorporate lemon curd: Gradually add lemon curd one tablespoon at a time, mixing gently until just combined to maintain pockets of tart lemon flavor throughout the batter.
  6. Add flour: Increase mixer speed and gradually add the all-purpose flour, blending until no streaks remain and the batter is smooth but thick.
  7. Transfer and spread batter: Press the batter evenly into the prepared baking pan. To prevent sticking, lightly grease your hands if necessary while smoothing the top for uniform thickness.
  8. Bake: Bake in the preheated oven for approximately 30 minutes, or until the edges are golden and a toothpick inserted near the center comes out with moist crumbs but no wet batter.
  9. Cool and cut: Allow the blondies to cool completely in the pan on a wire rack. Using the parchment overhang, lift the bars out of the pan. With a sharp knife, cut into 9 equal square pieces.
  10. Store: Store the blondie bars in an airtight container at room temperature for up to 3 days, or refrigerate for longer freshness.

Notes

  • For best results, use room temperature butter and eggs to ensure smooth mixing and proper texture.
  • Do not overmix the batter once the flour is added to avoid tough blondies.
  • Lemon curd can be homemade or store-bought; homemade lemon curd will enhance the fresh lemon flavor.
  • If you prefer a stronger lemon taste, increase the lemon zest to zest of 2 lemons.
  • These blondies are best served at room temperature but can be slightly warmed for a softer texture.
