Ingredients

Scale
  • 1 cup (226 g/2 sticks) unsalted butter, melted
  • 2 large eggs
  • 1 cup granulated sugar
  • ½ cup brown sugar, packed
  • ¼ cup (60 ml) fresh lemon juice
  • 1 tbsp lemon zest (from about 2 lemons)
  • 1 tsp vanilla extract
  • 2 cups all-purpose flour
  • 1 ½ tbsps poppy seeds
  • 1 tsp baking powder
  • ½ tsp salt
  • 1 cup powdered sugar
  • 2 tbsps fresh lemon juice
  • ½ tsp vanilla extract
  • 1 tsp lemon zest

Instructions

  1. Oven Preparation: Warm the oven to 350F (175C) and prepare a 9×13-inch baking pan with parchment paper or a light grease coating.
  2. Wet Ingredient Fusion: Combine melted butter, granulated and brown sugars in a large mixing bowl, creating a smooth base. Introduce eggs, vibrant lemon zest, fresh lemon juice, and vanilla extract, whisking until perfectly integrated.
  3. Dry Ingredient Blend: Separately, unite flour, baking powder, salt, and poppy seeds through a gentle whisking motion, ensuring uniform distribution.
  4. Batter Creation: Gradually fold dry ingredients into the wet mixture, mixing with a delicate touch to prevent overmixing. Transfer the silky batter into the prepared pan, spreading evenly with a spatula.
  5. Baking Process: Place in the preheated oven and bake for 22-28 minutes. Test for doneness by inserting a toothpick – it should emerge clean and pristine.
  6. Cooling & Glazing Preparation: Allow the baked bars to cool completely within the pan. Meanwhile, craft a glossy glaze by whisking powdered sugar, bright lemon juice, vanilla extract, and zesty lemon zest until achieving a smooth, luxurious consistency.
  7. Final Touch: Artfully drizzle or spread the glaze over the cooled bars, allowing it to set for approximately 15 minutes before slicing into elegant squares.

Notes

  • Avoid overmixing the batter to prevent tough, dense bars. Stir just until dry ingredients are incorporated for a tender, light texture.
  • Adjust lemon zest and juice量 based on personal preference. Fresh lemons provide the most vibrant citrus flavor compared to bottled juice.
  • Check bars early to prevent overbaking. Toothpick test is crucial – a few moist crumbs are okay, but avoid wet batter for ideal moisture.
  • Substitute all-purpose flour with a 1:1 gluten-free flour blend to make the recipe celiac-friendly without compromising texture.
