These Lemon Brownies are soft, fudgy citrus bars finished with a glossy white chocolate lemon glaze. The best part? The whole thing comes together in one bowl. If I were hosting a Spring dinner party, I would make you my spring pea pesto with bacon and leeks and definitely serve these lemon brownies for dessert.
It’s no secret I’m obsessed with lemon recipes โ from limoncello tiramisu to lemon crinkle cookies and lemon cake, it’s my favorite flavor for sweet treats. These lemon brownies feel like sunshine in bar form: bright and pillowy, where chocolate brownies feel more late-night, these feel more daytime. Rubbing the zest into the sugar deepens the lemon flavor without tipping into tart, and the creamy white chocolate glaze ties it all together perfectly.
Testing Notes
I knew I wanted these lemon brownies to be fudgy yet soft, with a bright lemon flavor, but it took a few tries to get there.
Test #1 used melted butter and white chocolate in the batter, resulting in a thick, fudgy lemon brownie. It was a solid start, but I felt it needed more moisture, lift, and lemon flavor.
Test #2 swapped a portion of granulated sugar for brown sugar, added baking powder, and increased the lemon zest. The lemon flavor was great, but the brownie turned out too gooey in the center and a bit darker in color. On top of that, both versions were too rich to pair well with a glaze and I really wanted a glaze.
Test #3 was the turning point. I creamed the butter and sugar together to encourage a lighter, fluffier texture, and instead of mixing the white chocolate into the batter, I used it to make a glaze. SO GOOD! The creamy white chocolate glaze paired with the bright lemon flavor is a combination I didn’t know I needed. Wow, they’re truly made for each other.
Ingredients Youโll Need for Lemon Brownies
- Lemon zest + juice – I like to use fresh lemons, bottled lemon juice can have a bitter taste. The zest is going to really infuse that bright lemon flavor.
- Granulated sugar – Sweetens everything and does double duty by soaking up the lemon oils when you rub in the zest. Don’t skip that step.
- Unsalted butter – Keeps these rich and fudgy.
- Vanilla extract – Something about the hint of vanilla rounds out this dessert so well. It’s just slightly creamsicle, and I love that.
- All-purpose flour – Just enough to hold things together without making these feel too cakey. We want a brownie-like texture.
- White chocolate – Melted into a simple glaze, it adds a creamy sweetness that balances all that bright lemon.

How to Make Lemon Brownies
- Infuse the sugar with lemon. In a large bowl, rub the sugar and lemon zest together with your fingers until the sugar becomes fragrant.
- Cream the butter and sugar. Add the softened butter, vanilla extract, and lemon extract. Beat with a hand mixer until light and fluffy. Then mix in the lemon juices and eggs.
- Add the dry ingredients. Beat in the flour, baking powder, and salt.
- Spread the batter evenly in the prepared pan. Bake for about 25 minutes on 350โ.
- Make the glaze. Heat the white chocolate with the lemon juice. Add the lemon extract and salt.
- Spread the glaze over the brownies and sprinkle with lemon zest. Let set for 20 minutes.
- Slice and serve!
Quick Tips for the Best Lemon Brownies
- Donโt overmix the batter. Once the flour is added, mix just until combined to keep the brownies tender. Overmixing can encourage gluten to form.
- Let the brownies cool a bit before glazing. If the bars are too warm, the glaze will melt and become runny rather than setting into a smooth layer.
Storage
- Store leftover brownies in an airtight container at room temperature for up to 2 days.

Ingredients
- 1 ยผ cup (272g) granulated sugar
- 2 tablespoons lemon zest, (from about 2 lemons)
- ยพ cup unsalted butter, softened
- 1 teaspoon vanilla extract
- 1 teaspoon lemon extract
- 2 tablespoons lemon juice
- 2 large eggs
- 1 ยผ cup all-purpose flour
- ยพ teaspoon baking powder
- ยฝ teaspoon kosher salt
White Chocolate Lemon Glaze:
- ยพ cup (113g) white chocolate , roughly chopped
- 2 tablespoons lemon juice
- ยผ teaspoon lemon extract
- Pinch kosher salt
- 1 tablespoon lemon zest, for garnish
Instructions
- Preheat the oven to 350โ. Grease and line an 8x8inch pan and place a piece of parchment that spans just the center length with the ends of the parchment hanging over the edge of the pan. Press the parchment flat so it adheres to the bottom and sides of the pan.
- In a large bowl, add the sugar and the lemon zest. Use your fingers to rub the zest into the sugar to release the oils. This will really bring out the lemon flavor from the zest.
- Next add the butter, lemon extract, and vanilla extract. Using a hand mixer on medium speed, beat the butter and sugar together until fluffy about 1 minute.
- Then add lemon juice and eggs. Quickly beat together on medium speed until combined and smooth.
- Now, add your dry ingredients: flour, baking powder, salt. Beat on low speed until combined. Scoop the batter into the prepared baking dish. Bake the lemon brownies for 25 minutes until slightly golden on the edges and a toothpick inserted into the center comes out clean. Let cool for about 15 minutes.
To Make the White Chocolate Lemon Glaze:
- Meanwhile, make the white chocolate lemon glaze. Add the white chocolate and lemon juice to a small bowl. Microwave in intervals of 20 seconds, until the white chocolate has completely melted. (If you donโt have a microwave, use a double boiler.) Stir until combined and glossy. Then stir in the lemon extract and salt.
- Pour the white chocolate lemon glaze over the lemon brownies and move the pan around to encourage the glaze to cover the surface of the lemon brownies. Finally, top with the lemon zest. Allow the glaze to set for at least 20 minutes before slicing.
Notes
- Donโt overmix the batter. Once the flour is added, mix just until combined to keep the brownies tender. Overmixing can encourage gluten to form.
- Let the brownies cool a bit before glazing. If the bars are too warm, the glaze will melt and become runny rather than setting into a smooth layer.
