Ingredients
  

Blondie Base

  • 1/2 cup butter (salted or unsalted, melted and cooled down) Provides richness and moisture
  • 1/2 cup granulated sugar Adds sweetness and contributes to texture
  • 1/4 cup powdered sugar For a softer texture
  • 2 large eggs (at room temperature) Binds ingredients and adds moisture
  • 2 tbsp lemon zest For fresh citrus flavor
  • 1 tbsp lemon juice Adds acidity and brightness
  • 2 tsp vanilla extract Enhances flavor
  • 1 tsp lemon extract Boosts lemon flavor
  • 1 cup all-purpose flour (sifted) Provides structure
  • 1/4 tsp salt Balances sweetness

Frosting

  • 1 cup powdered sugar (without cornstarch preferably) For frosting
  • 2 tbsp lemon juice Adds moisture and flavor to frosting
  • 1 tbsp lemon zest Optional, for enhanced flavor in frosting

Instructions
 

Preparation

  • Preheat your oven to the appropriate temperature and lightly grease a baking pan.
  • In a mixing bowl, whisk together the melted butter and granulated sugar until well combined.
  • Add the powdered sugar to the mixture and blend until velvety and well incorporated.
  • Incorporate the eggs, whisking gently until fully integrated.
  • Stir in the lemon zest, lemon juice, vanilla extract, and lemon extract.
  • Gradually fold in the sifted all-purpose flour and salt, being careful not to overmix.

Baking

  • Pour the blondie batter into your prepared baking pan, smoothing the top.
  • Bake until set but slightly wobbly in the center. Check periodically.
  • Once lightly golden around the edges, remove from the oven and let cool in the pan.

Frosting and Serving

  • In a mixing bowl, combine powdered sugar with lemon juice and optional lemon zest until smooth.
  • Spread the lemon frosting generously over the cooled blondies.
  • Cut into squares or rectangles and enjoy!

Notes

For best results, use room temperature eggs, don’t overmix the batter, and allow the blondies to cool completely before frosting.
