The Best Lemon Brownies
When life gives you lemons, make lemon bars! You will thank me later. These soft Lemon Brownie bars are a fun twist on the classic rich and decadent brownies. They may not have any cocoa or chocolate but they definitely have the texture and fudginess of the best homemade brownies.
These Lemon Brownies or Blondies are like sunshine on a plate. The perfect treat for spring and summer. They are the perfect citrus snack and a great addition to your dessert table. Serve them at your next gathering or get together, at a holiday party, backyard BBQ or bring them to your next potluck.
Lemon Brownie Ingredients
- Flour: I use all-purpose flour to make this recipe.
- Butter: Unsalted and softened to room temperature.
- Lemon: You’ll be using lemon juice and lemon zest so fresh lemons are a must!
- Eggs: I use large eggs.
- Sugar: Granulated sugar for the brownie bars and confectioners’ sugar for the glaze.
- Baking Powder and Salt: I use sea salt or Kosher salt for baking.
How To Make Lemon Brownie Bars
- Get Everything Ready: Preheat the oven and line a 9×13 baking pan with parchment paper, leaving an overhang, so you can pull the brownie out of the pan when done.
- Whisk Dry Ingredients: Whisk the flour, baking powder and salt until combined. Set aside.
- Mix Wet Ingredients: In the bowl of a stand mixer fitted with the paddle attachment, or a handheld mixer, beat together the butter, sugar, lemon zest and lemon juice until light and fluffy. Add the eggs one at a time and mix until just combined.
- Add Dry Ingredients to Wet Ingredients: Gradually stir in the dry ingredients until combined.
- Bake: Pour the batter into the prepared pan, and smooth out the surface with a spatula. Bake until a toothpick inserted in the center comes out clean with just a few moist crumbs. Don’t over bake! Remove from the oven and cool.
- Make the Glaze: Whisk together the confectioners’ sugar, lemon juice and zest in a mixing bowl. Add additional confectioners’ sugar or lemon juice as needed until you reach a nice glaze consistency.
- Glaze: Pour the glaze over the brownies and spread evenly. Allow to set for 6 hours or overnight.
Storing and Freezing
These citrus lemon blondies or brownies can be kept on the counter at room temperature for 2 days. You can also store these brownies in an airtight container in the refrigerator for about a week.
These delicious dessert bars can be frozen. I recommend you freeze them without the glaze. Cool the brownies completely, then wrap them tightly with plastic wrap and aluminum foil. They will keep in the freezer for 2 months. Thaw overnight in the fridge and bring them to room temperature before serving.
Lemon Brownie Recipe Tips
- make sure not to over bake these bars. You want them to be chewy and fudgy.
- After pouring the glaze over the brownies, you can cut the time they need for the glaze to set by placing them in the freezer for one hour.
- Use real lemons not the one in the bottle!
- Room temperature lemons are juicier than refrigerated ones.
- To get the most juice from a lemon, roll it back and forth on the kitchen counter, pressing them gently with the palm of your hand.
