Lemon Brownies

Posted on

These Lemon Brownies are soft, gooey, and packed with a tangy lemon punch. The sweet and tangy lemon glaze enhances the flavor, making every bite a burst of citrus delight. With a fudgy texture and fresh lemon zing, these brownies are an easy and delicious treat. You can whip them up in about 20 minutes, and with some baking time, you’ll be enjoying them in under an hour. They’re a perfect dessert for lemon lovers!

Tips for Making the Best Lemon Brownies:

  1. Make the Lemon Sugar: Don’t skip this step! Rubbing the sugar with lemon zest releases tons of flavor.
  2. Hand-Mix the Batter: Use a whisk instead of an electric mixer to avoid overmixing, which can add too much air and cause the brownies to rise and then sink.
  3. Don’t Overbake: Overbaking will make them dry instead of gooey.
  4. Set the Glaze: Let the glaze set before slicing.
  5. Use Quality White Chocolate: Good quality white chocolate makes a big difference in taste.

Lemon Brownies:

  • Preheat Oven: Set the oven to 350°F. (See notes if your oven runs hot.)
  • Prepare Pan: Grease and line an 8×8-inch square pan with parchment paper.
  • Make Lemon Sugar: In a bowl, combine the sugar and lemon zest. Rub them together with your fingers to release the lemon oils.
  • Melt Chocolate and Butter: In a large mixing bowl, add the chopped white chocolate and butter. Microwave in 15-second intervals until melted, then whisk until smooth.
  • Combine Ingredients: Add the lemon sugar to the melted mixture and whisk. Add the eggs and whisk. Then, add the lemon juice and mix.
  • Mix Batter: Add the flour and salt, whisking until smooth.
  • Bake: Pour the batter into the prepared pan and bake for about 35 minutes or until the top is set. A toothpick inserted should come out with no moist crumbs.
  • Cool: Let the brownies cool for about 20 minutes.

Lemon Glaze:

  • Prepare Glaze: In a medium bowl, mix the powdered sugar with lemon juice, starting with 1 tablespoon and adding more as needed.
  • Glaze Brownies: Pour the glaze over the brownies and spread with a spatula. Add lemon zest to the glaze or sprinkle it on top.
  • Set Glaze: Allow the glaze to set for 10-15 minutes before slicing and serving.


Counter: Store in an airtight container at room temperature for up to 1 day.
Fridge: For longer storage, keep in the fridge and bring to room temperature before serving.
Oven Temperature: Use 325°F for hot, convection, or gas ovens.
  • Add ¼ tsp almond extract for a different flavor.
  • Try other citrus fruits like oranges or limes.
  • Skip the glaze and dust with powdered sugar.
Pan Size: Use an 8×8-inch pan for best results. For a 9×9-inch pan, multiply ingredients by 1.5.
Lemon Sugar: You can also process the sugar and lemon zest in a food processor.
White Chocolate: Use high-quality white chocolate for the best taste. Brands like Lindt, Callebaut, or Valrhona are great, but store brands are fine if that’s what you have.
