I remember the first time I made these. My friend Sarah was having a rough week, and I wanted to bake her something that would just *cheer her up*, you know? I stumbled across a lemon brownie recipe and thought, “Why not?” Oh my goodness, the smell alone was enough to make everyone in the house happy! They disappeared in about five minutes flat.

Why You’ll Love These Lemon Brownies [40 Minutes]

Quick and Easy Dessert

Seriously, who has hours to spend baking? Not me! These lemon brownies are ready in just 40 minutes. That’s it! Perfect for when you need a sweet treat, FAST.

Moist and Flavorful Lemon Brownies

Forget dry, crumbly brownies. These are seriously moist and chewy, with a bright, lemony flavor that’ll make your taste buds sing! Trust me, you’ll be hooked.

Perfect Balance of Sweet and Tangy

My favorite part is that they’re not *too* sweet. The lemon cuts through the sugar perfectly, giving you that awesome sweet and tangy combo. It’s like sunshine in every bite!

Ingredients for Lemon Brownies [40 Minutes]

Alright, let’s gather everything we need! Nothing too fancy here, promise. But a little care with your ingredients makes ALL the difference. Fresh is best, remember?

For the Lemon Brownies

3/4 cup all-purpose flour

Yep, just regular all-purpose flour. Make sure you’re using a standard measuring cup for accuracy, okay?

3/4 cup granulated sugar

The sweet stuff! This is what gives our lemon brownies that lovely sweetness.

1/4 tsp salt

Don’t skip the salt! It balances the sweetness and really brings out the lemon flavor. Trust me!

1/4 tsp baking powder

Just a smidge to give the brownies a little lift and the perfect texture.

1/2 cup unsalted butter, softened

This is important! Make sure the butter is softened to room temperature, not melted. You want it nice and creamy. I usually leave mine out for about an hour before I start baking.

2 large eggs

Adds richness and binds everything together. Simple as that!

2 tbsp lemon zest (from about 2 lemons)

Gotta have that zest! Fresh zest is key here – it’s where all that amazing lemon oil and flavor is hiding. Don’t skimp!

2 tbsp lemon juice (from about 1/2 lemon)

Freshly squeezed, of course! Bottled juice just doesn’t have the same zing.

For the Lemon Glaze

1 cup powdered sugar

This makes the glaze perfectly smooth and sweet.

2-3 tbsp lemon juice (adjust for desired consistency)

More fresh lemon juice! This is what gives the glaze its tangy kick. Add it a little at a time until you get the perfect pourable consistency.

Optional Garnish

Additional lemon zest (for garnish)

Okay, this is totally optional, but I love sprinkling a little extra fresh lemon zest on top of the glaze. It just makes them look so pretty and adds an extra burst of lemon flavor!

How to Make Lemon Brownies [40 Minutes]: Step-by-Step Instructions

Preparing the Pan and Oven

Preheat the oven to 350°F (175°C).

First things first, get that oven preheating! You don’t want to put your lemon brownies in before it’s ready. I like to give mine a good 15-20 minutes to heat up properly.

Line an 8×8 inch baking pan with parchment paper, leaving an overhang.

This is my *favorite* trick for easy cleanup and perfect brownie removal. Just cut a piece of parchment paper that’s wide enough to hang over the sides of the pan. This way, you can just lift the finished lemon brownies right out! No sticking, no mess. You’ll thank me later!

Mixing the Dry Ingredients

In a medium bowl, whisk together the flour, sugar, salt, and baking powder.

Okay, time to get those dry ingredients combined! Just grab a medium bowl and whisk everything together until it’s nicely mixed. This helps distribute the baking powder and salt evenly, so you don’t end up with weird pockets of flavor. Nobody wants a salty brownie!

Combining Wet and Dry Ingredients

Cream the softened butter until smooth. Add eggs one at a time, then mix in lemon zest and juice.

Now for the good stuff! In a large bowl, cream that softened butter until it’s nice and smooth. I use an electric mixer for this, but you can totally do it by hand if you’re feeling ambitious! Then, add the eggs one at a time, mixing well after each addition. This ensures they’re fully incorporated. Finally, stir in the lemon zest and juice. The smell at this point is AMAZING.

Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined.

Alright, slow and steady wins the race here! Gradually add the dry ingredients to the wet ingredients, mixing on low speed. The key is to mix until *just* combined. Don’t overmix! Overmixing will develop the gluten in the flour and make your lemon brownies tough. We want them soft and chewy, remember?

Baking the Lemon Brownies [40 Minutes]

Pour the batter into the prepared pan and smooth the top.

Pour that gorgeous batter into your prepared pan and use a spatula to smooth it out evenly. This will help your lemon brownies bake evenly too.

Bake for 22-25 minutes, or until a toothpick comes out clean or with a few moist crumbs.

Pop the pan into the preheated oven and bake for 22-25 minutes. Keep an eye on them! You want the edges to be set and lightly golden, and a toothpick inserted into the center should come out clean or with just a few moist crumbs. Don’t overbake, or they’ll be dry! Remember, moist and chewy is the goal.

Making the Lemon Glaze

Whisk together powdered sugar and lemon juice until smooth, adjusting consistency as needed.

While the lemon brownies are baking (or cooling), whip up the glaze! In a bowl, whisk together the powdered sugar and lemon juice until it’s smooth and creamy. If it’s too thick, add a little more lemon juice. If it’s too thin, add a little more powdered sugar. You want it to be pourable but not too runny.

Glazing and Serving the Lemon Brownies [40 Minutes]

Cool the brownies completely, then pour the glaze over the top.

This is super important: let the lemon brownies cool *completely* in the pan before glazing. If you glaze them while they’re still warm, the glaze will just melt right off. Patience, my friend! I know it’s hard, but trust me, it’s worth it.

Spread evenly and sprinkle with additional lemon zest if desired. Let the glaze set before slicing.

Once the lemon brownies are completely cool, pour the glaze over the top and spread it out evenly. If you’re feeling fancy, sprinkle on some extra lemon zest for a pop of color and flavor. Then, let the glaze set completely before slicing and serving. Enjoy!

Tips for the Best Lemon Brownies [40 Minutes]

Use Fresh, High-Quality Ingredients

Seriously, this makes a HUGE difference! Splurge on some good lemons. Fresh lemon juice and zest are what give these brownies that incredible bright flavor. Don’t even think about using that bottled stuff for the zest!

Don’t Overbake the Lemon Brownies

This is brownie rule number one! Overbaked brownies are sad brownies. Keep a close eye on them and pull them out when a toothpick comes out with just a few moist crumbs. They’ll continue to bake a little as they cool, so err on the side of slightly underbaked. You want them nice and fudgy!

Cool Completely Before Glazing

I know, waiting is the hardest part! But trust me on this one. If you try to glaze those lemon brownies while they’re still warm, the glaze will just melt right off into a sugary puddle. Let them cool completely, and you’ll get that perfect, pretty glaze on top.

Ingredient Notes and Substitutions for Lemon Brownies

Okay, so maybe you’re missing an ingredient, or you have some dietary restrictions? No problem! Here are a few easy swaps you can make without sacrificing too much of that yummy lemon brownie goodness.

Flour Substitutions

Want to make these gluten-free? Go for it! I’ve had great luck using a 1:1 gluten-free all-purpose flour blend. Just make sure it contains xanthan gum to help with the texture, okay?

Butter Alternatives

If you’re dairy-free, you can totally use melted coconut oil or even a good-quality margarine instead of butter. Just be aware that it might slightly alter the flavor and texture, but they’ll still be delicious, I promise!

Lemon Extract

Oops, no fresh lemons? Don’t panic! You can use lemon extract in a pinch. I’d start with about 1 teaspoon of lemon extract in the batter and another 1/2 teaspoon in the glaze, and then adjust to taste. But seriously, fresh is always best if you can swing it!

Frequently Asked Questions About Lemon Brownies [40 Minutes]

Can I use bottled lemon juice?

Okay, listen, fresh lemon juice is *always* gonna be better. It’s brighter, more flavorful, and just…well, fresher! But, hey, I get it. Sometimes you’re in a pinch. If you absolutely *have* to use bottled lemon juice, go for it. Just try to get a good quality one, and maybe add a tiny bit more zest to compensate, okay?

How do I store these Lemon Brownies?

These lemon brownies are best stored in an airtight container at room temperature. They’ll stay nice and moist for about 3-4 days. But let’s be real, they probably won’t last that long! Mine usually disappear within a day or two, tops!

Can I freeze Lemon Brownies?

Yep! You can totally freeze these lemon brownies. Just wrap them individually in plastic wrap and then place them in a freezer-safe bag or container. They’ll keep in the freezer for up to 2-3 months. When you’re ready to eat them, just thaw them at room temperature for a couple of hours. They might be a *tad* less moist, but still super yummy!

Why are my Lemon Brownies dry?

Oh no! Dry brownies are a bummer. Usually, that happens when you overbake them. Make sure you’re checking them with a toothpick and pulling them out when it comes out with just a few moist crumbs. Also, make sure you’re measuring your ingredients accurately. Too much flour can also lead to dry brownies. And hey, maybe your oven runs hot? Every oven is different, ya know!
