Ingredients

  

For the Lemon Brownie Bars

• 1/2 cup unsalted butter melted (113g)
• 1 3/4 cups granulated sugar (350g)
• 3 large eggs
• 1 tsp vanilla extract
• 1 1/2 cups all-purpose flour (180g)
• 1/2 tsp baking powder
• 1/4 tsp salt
• 2 tbsp lemon zest from 2-3 lemons
• 1/4 cup fresh lemon juice from 1-2 lemons

For the Lemon Glaze

• 2 cups powdered sugar sifted (240g)
• 4-5 tbsp fresh lemon juice

Equipment

• 9×13 inch baking pan
• Parchment Paper
• Large Mixing Bowl
• Medium Mixing Bowl
• Whisk
• Zester
• Juicer

Method

 

1. Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving an overhang on the sides to easily lift the bars out later. Lightly grease the parchment paper.
2. In a large mixing bowl, whisk together the melted butter and granulated sugar until well combined. Beat in the eggs one at a time, then stir in the vanilla extract until smooth.
3. In a separate medium bowl, whisk together the all-purpose flour, baking powder, and salt.
4. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix, as this can lead to tough bars.
5. Gently fold in the lemon zest and fresh lemon juice until evenly distributed throughout the batter.
6. Pour the batter into the prepared baking pan and spread evenly. Bake for 25-30 minutes, or until the edges are lightly golden and a toothpick inserted into the center comes out with moist crumbs attached (it shouldn’t be completely clean, as these are meant to be fudgy).
7. Remove the pan from the oven and let the bars cool completely in the pan on a wire rack. This step is crucial before glazing to prevent the glaze from melting.
8. Once the bars are completely cool, prepare the glaze. In a medium bowl, whisk together the sifted powdered sugar and 4 tablespoons of fresh lemon juice until smooth. If the glaze is too thick, add the remaining lemon juice a teaspoon at a time until you reach a pourable but still thick consistency.
9. Pour the lemon glaze evenly over the cooled bars, spreading with a spatula if necessary to cover the entire surface.
10. Allow the glaze to set for at least 30 minutes at room temperature, or transfer the pan to the refrigerator for 15-20 minutes to speed up setting. Once the glaze is firm, use the parchment paper overhang to lift the entire slab of bars out of the pan. Place on a cutting board and slice into 16 squares (4×4 arrangement).

Notes

For an extra burst of lemon, you can add 1/2 teaspoon of lemon extract to the brownie batter. Store leftover lemon brownie bars in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to 5 days. Chilling the bars before cutting makes for cleaner slices. Use a hot, sharp knife, wiping it clean after each cut for the best results.

Pro Tips for Making This Lemon Brownie Bars Recipe

For truly spectacular results with your Lemon Brownie Bars Recipe, I’ve gathered a few tried-and-true tips from my own kitchen adventures. These little touches can make all the difference, ensuring your bars are as delightful as can be.

My Secret Trick: I always make sure my butter and eggs are at room temperature. It helps them emulsify better, leading to a much smoother batter and a more tender, even crumb in your lemon brownie bars.

When zesting your lemons, be sure to only get the bright yellow part, avoiding the white pith underneath. The pith can be bitter and will detract from the sweet-tart flavor we’re aiming for in this Lemon Brownie Bars Recipe.

Don’t overmix the batter once you add the flour. Just mix until everything is combined to avoid tough bars. A gentle hand is key to a perfectly tender texture.

To ensure your glaze is perfectly smooth and spreadable, sift your powdered sugar before mixing it with the lemon juice. This prevents any lumps and gives you a beautifully even finish.

Fun Variations for Lemon Brownie Bars Recipe

One of the greatest joys of baking is getting creative, and this Lemon Brownie Bars Recipe is wonderfully adaptable! Here are a few ways to sprinkle in some extra magic, just as I love to do in my kitchen.

Berry Bliss Twist

My sister always asks me to swirl in a handful of fresh raspberries or blueberries into the batter before baking. The berries burst with a lovely tartness that beautifully complements the lemon, adding a delightful pop of color and flavor to your Lemon Brownie Bars Recipe.

Coconut Sunshine

For a tropical touch, try adding about half a cup of shredded unsweetened coconut to the batter. The coconut adds a lovely texture and a hint of exotic sweetness that pairs wonderfully with the bright lemon. It reminds me of a delightful treat I once shared with friends on a summer afternoon.

Poppy Seed Perfection

If you love a little crunch and a subtle nutty flavor, stir in a tablespoon of poppy seeds with your dry ingredients. They add a charming visual appeal and a delicate texture to these delightful lemon brownie bars, creating a classic lemon-poppy seed combination that’s always a hit.

What to Serve With Lemon Brownie Bars Recipe

These delightful Lemon Brownie Bars Recipe with their sweet-tart glaze are truly wonderful on their own, but a few simple accompaniments can elevate them into an even more memorable dessert experience. Just like a good story, every sweet treat can be enhanced by its companions.

I love serving these lemon brownie bars with a dollop of freshly whipped cream. The light, airy sweetness of the cream is a perfect foil to the tangy lemon, creating a harmonious balance of flavors.

For an extra touch of indulgence, a scoop of creamy vanilla bean ice cream is a classic pairing. The cool, smooth ice cream against the chewy, zesty bar is a match made in dessert heaven, especially on a warm day.

A simple cup of your favorite herbal tea, perhaps a calming chamomile or a refreshing peppermint, makes for a lovely, comforting pairing. And my mom always says a good cup of coffee brings out the best in any sweet treat, so a freshly brewed cup would be a fantastic companion too!

How to Store Lemon Brownie Bars Recipe

Once your kitchen has been filled with the glorious aroma of this Lemon Brownie Bars Recipe, you’ll want to make sure any leftovers stay as fresh and delicious as possible. Proper storage is key to preserving that wonderful flavor and tender texture.

Keeping Them Fresh in the Fridge

To keep your lemon brownie bars at their best, I recommend storing them in an airtight container in the refrigerator. They’ll stay wonderfully fresh for up to 3-4 days. The cool environment helps maintain their structure and keeps the glaze from getting sticky. Before serving, I like to let them come to room temperature for about 15-20 minutes, which really brings out their vibrant lemon flavor.

Freezer Friendly Tips

If you’ve managed to bake a larger batch or want to save some for a rainy day, these lemon brownie bars freeze beautifully! Once completely cooled, cut them into individual portions. Wrap each bar tightly in plastic wrap, then place them in a freezer-safe bag or container. They’ll keep well in the freezer for up to 3 months. When you’re ready to enjoy, simply thaw them at room temperature or warm them gently in the microwave for a few seconds. A light dusting of powdered sugar after reheating brings it back to life, making them taste freshly baked!

FAQs

Faq 1

Can I use bottled lemon juice instead of fresh?
While fresh lemon juice and zest are highly recommended for the best flavor in this Lemon Brownie Bars Recipe, you can use bottled lemon juice in a pinch for the glaze. However, for the bars themselves, fresh zest and juice really make a difference.

My glaze is too thick/thin. What should I do?
If your glaze for the Lemon Brownie Bars Recipe is too thick, add a tiny bit more lemon juice, a few drops at a time, until it reaches your desired consistency. If it’s too thin, whisk in a little more powdered sugar.

Can I make these dairy-free?
You can experiment with a dairy-free butter substitute for this Lemon Brownie Bars Recipe, though the texture might vary slightly. Ensure all other ingredients are also dairy-free to meet your dietary needs.
