What are Lemon Brownies?

Lemon brownies are a citrusy twist on the classic brownie! Unlike traditional chocolate-based brownies, lemon brownies are made with lemon juice and zest to give them a bright, tangy flavor (similar to lemon bars). They have a dense, slightly chewy, fudgy texture (similar to my fudgy brownie recipe) but with a refreshing lemon taste. They are a lemon lovers perfect dessert!

Many lemon brownie recipes also opt to use a lemon glaze (which I have chosen to do as well – they really take the brownies to another level!) to further enhance their lemon flavor and add a bit of extra sweetness.

Why You’ll Love These Brownies

Flavor: These lemon brownies are one of my favorite lemon desserts because they’re packed with SO MUCH lemon flavor.

Texture: I had to do a bit of experimenting with this recipe to get the perfect fudgy texture. I found that using warm melted butter and only cooking the brownies until they were almost done made for the best texture. I also found that using no baking powder or baking soda (and only relying on eggs to provide a little leavening) made for dense lemon brownies that didn’t just taste like a thin lemon cake.

Ease: These lemon brownies are SO SO easy to make! They come together quickly and don’t require an electric mixer.

How to make Lemon Brownies

Preheat oven to 180 °C (350°F) conventional and grease a square 8×8 inch cake tin (I use my homemade cake release). Once greased, line with a piece of parchment paper that is long enough so there is some overhang on two opposite edges of the tin. This will make it easier to pull the brownies out once done.

Sift together flour, cornstarch and salt. Using a whisk or fork, mix until well combined and set aside for now.

In a large mixing bowl add in white sugar and fresh lemon zest. Using your fingers, rub the lemon zest into the sugar until the sugar has a light yellow tinge to it (about 30 seconds).

Add in warm melted butter, unflavored vegetable oil, eggs, fresh lemon juice and vanilla. Using a whisk, mix until combined and smooth, but avoid overmixing (you don’t want to incorporate too many air bubbles into the batter).

Add in the dry ingredients from earlier to the wet mixture and using a rubber spatula, gently fold until just combined. Do not overmix.

Pour the batter into the prepared baking pan (the batter should be thin). Give the tin a little shake to evenly distribute the batter and then drop it lightly on the counter twice. Bake for 22 minutes, or until a toothpick comes out almost clean (you want to have a very small amount of uncooked batter or moist crumbs on the toothpick – this will ensure the brownies don’t overbake).

Allow to completely cool in the cake tin (1-2 hours).

Once cooled, run a thin knife (or spatula) around the edges of the pan that have no parchment paper and then carefully use the excess parchment paper hanging over the edges to carefully lift the brownie out of the cake pan.

Prepare the lemon glaze by combining the powdered sugar and lemon juice. Mix with a spoon until combined and smooth. You want the glaze to be thick, but spreadable.

Spread the glaze evenly over the top of the brownie (I use my offset spatula, but the back of a spoon will do the trick too). Allow it to set for 30 mins to an hour (you should be able to touch the top without any of the frosting sticking to your finger) and then slice and serve!

Ingredients
 

Lemon Brownie Base

  • 1¼ cups (150 g) all purpose flour
  • 2 tbsp (14 g) cornstarch
  • ½ tsp salt
  • 1¼ cups (250 g) white granulated sugar
  • 2 tbsp fresh lemon zest - See note 1
  • ¾ cup (170 g) warm melted unsalted butter - make sure the butter is warm (not hot or cold) when adding it to the batter
  • 1 tbsp (13 g) unflavored vegetable oil
  • 2 large eggs - room temperature
  • 3 tbsp (42 g) freshly squeezed lemon juice
  • ½ tsp vanilla extract/essence

Lemon Glaze

  • 1 cup (125 g) powdered sugar - also known as icing/confectioners sugar
  • 1½ tbsp (22 g) freshly squeezed lemon juice

Instructions

  • Preheat oven to 180 °C (350°F) conventional (see note 2 if using a convection oven with a fan) and grease a square 8x8 inch cake tin (I use my homemade cake release). Once greased, line with a piece of parchment paper that is long enough so there is some overhang on two opposite edges of the tin. This will make it easier to pull the brownies out once done.
  • Sift together flour, cornstarch and salt. Using a whisk or fork, mix until well combined and set aside for now.
  • In a large mixing bowl add in white sugar and fresh lemon zest. Using your fingers, rub the lemon zest into the sugar until the sugar has a light yellow tinge to it (about 30 seconds).
  • Add in warm melted butter, unflavored vegetable oil, eggs, lemon juice and vanilla. Using a whisk, mix until combined and smooth, but avoid overmixing (you don't want to incorporate too many air bubbles into the batter).
  • Add in the dry ingredients from earlier and using a spatula, gently fold until just combined. Do not overmix.

  • Spread the glaze evenly over the top of the brownie. Allow it to set for 30 mins to an hour (you should be able to touch the top without any of the frosting sticking to your finger) and then slice and serve!

Notes

Note 1. When zesting the lemons, you want to make sure you're using a fine grater, and only grate the top yellow part of the lemon. Don't grate it right to the white part of the lemon as the white part is bitter so we don't want it in our brownies 🙂
Note 2. If using a convection oven with a fan, bake at 160C/320F
Note 3. If your glaze is too thin, you can add more powdered sugar. If it's too thick you can add more lemon juice.
