Lemon Brownies Ingredients

Lemon Brownies raw ingredients that are labeled

You’ll need:

For the Brownies

  • ½ cup of vegetable oil
  • 1 cup of granulated sugar
  • 1 teaspoon of lemon extract
  • 1 teaspoon of vanilla extract
  • Zest of 1 lemon, about 2 teaspoons
  • 2 tablespoons of fresh lemon juice
  • 2 large eggs plus 1 egg yolk, room temperature
  • 1 cup of all-purpose flour
  • ½ teaspoon of salt
  • ½ teaspoon of baking powder

For the Glaze

  • 1 cup of powdered sugar
  • 2 tablespoons of water
  • 1 teaspoon of lemon extract
  • 1 teaspoon of lemon juice or more water
  • 1 to 2 teaspoons of lemon zest, optional garnish

SUBSTITUTIONS AND ADDITIONS

POWDERED SUGAR: A light dusting of extra powdered sugar over the glaze is a perfect way to add a bit of presentation flair and add a little extra sweetness to these brownies.

GLUTEN-FREE FLOUR: If you’re staying away from gluten, you can easily substitute the all-purpose flour for gluten-free flour in this easy recipe.

LEMON EXTRACT: If you don’t have any, you can make a lighter-tasting brownie by substituting vanilla extract, or leave it out altogether. You can also add some extra lemon zest instead in this easy lemon brownies recipe.

WHITE CHOCOLATE CHIPS: Mix ½ cup of white chocolate chips into your brownie batter for extra sweetness.

How To Make This Lemon Brownies Recipe

STEP ONE: To begin your lemon brownie prep, preheat your oven to 350°F, then line a 9×9-inch square glass baking pan with parchment paper and set it aside.

STEP TWO: Mix together the oil and sugar in a large mixing bowl. Use a hand mixer or stand mixer to combine them thoroughly.

OUR RECIPE DEVELOPER SAYS

The oil and the egg yolk help to produce an even thicker brownie. The extra egg yolk also gives the brownie a bit more saturated yellow color. You could always add food coloring for an even more vibrant-looking yellow brownie.

STEP THREE: Beat in the lemon extract, vanilla extract, lemon zest, and lemon juice. Then add one egg at a time and then the egg yolk, making sure you are mixing well between each one.

PRO TIP:

Add more or less lemon juice/extract/zest as you desire to adjust the depth of lemon flavor in the brownies and the glaze.

STEP FOUR: Stir together the flour, salt, and baking powder and add it to the wet ingredients.

STEP FIVE: Beat together for about 1 to 2 minutes until fluffy and well combined.

STEP SIX: Spread the batter into the prepared baking dish. Bake for 25 minutes. Remove from the oven and allow brownies to cool for 30 minutes before preparing the glaze.

STEP SEVEN: In a small bowl, whisk together the powdered sugar, water, lemon extract, and lemon juice until a smooth, paste-like glaze forms.

PRO TIP:

When mixing the glaze, add the liquid ingredients gradually to control the consistency of the glaze. Too much water/liquid will make a very runny and less opaque glaze. I like the white contrast to the brownie color, so I like the glaze to be more opaque and thick. The glaze is very sweet. Just a light glaze or even a drizzle would be great, too.

STEP EIGHT: Spread the sweet lemon glaze over top of the brownies. Allow brownies to cool completely and the glaze will set so that it’s dry to the touch. Then sprinkle with lemon zest to garnish.

STEP NINE: Cut cooled brownies into pieces and serve.

How To Serve

Enjoy a fresh lemon brownie the next time you are craving the texture of a fudgy brownie but with the refreshing taste of real lemon flavor. Add an iced tea or pineapple lemonade to wash the brownie down.

Commonly called brookies, you can also try this combination of chocolate brownies and cookies. We also love our chocolate peanut butter brownies.

Storage

IN THE FRIDGE: Store these delicious lemon brownies in an airtight container, either in the fridge or on the counter for 3 to 4 days.

IN THE FREEZER: Allow the glazed lemon brownies to cool, and do not glaze them. Fully wrap the bars in plastic wrap. Place them in freezer bags, and store them for up to 3 months. Defrost before serving.

    FABULOUS! I used my all purpose GF flour and these came out great! They got a bit wet on the bottom using the parchment/glass, so I used a regular baking pan the second time and they were perfect! Certainly didn’t need the glaze, but would be a nice sugar and lemon hit if you want it! I found them plenty sugary and lemony without the glaze. Great texture, and held up well for 2-3 days in a tupperware.

    Delish! Made these to complement the Blueberry Tarts. These was quick yet so very good. I froze them for a week, and iced them hours before serving. Froze very well. Iced when thawed and garnished with lemon zest. If you like lemon pound cake, you will love these.
