This zesty lemon brownie recipe delivers the perfect balance of tangy citrus and sweet, fudgy texture. Unlike traditional chocolate brownies, these bright bars feature fresh lemon in both the batter and glaze for an irresistible treat that's perfect year-round.
I first made these lemon brownies for a summer garden party and they disappeared within minutes. Now they're my go-to dessert when I need something impressive but don't have hours to spend in the kitchen.
Ingredients
- All purpose flour: Creates the perfect structure without being too heavy
- Granulated sugar: Balances the tartness of the lemons while creating that classic brownie texture
- Unsalted butter: Provides richness and that distinctive brownie mouthfeel; look for high-quality European butter for extra richness
- Fresh lemons: Absolutely essential; use organic when possible for the best flavor and brightest zest
- Vanilla extract: Adds depth that complements the lemon perfectly—choose pure rather than imitation
- Powdered sugar: Creates a smooth glaze that sets beautifully on top
Step-by-Step Instructions
- Prepare The Pan:
- Preheat your oven to 350°F and line an 8x8 inch baking dish with parchment paper leaving some overhang for easy removal. The parchment prevents sticking and makes cleanup effortless. If you prefer greasing instead, use butter not cooking spray for better flavor.
- Make The Batter:
- In a large bowl whisk the dry ingredients until no lumps remain. In a separate bowl combine the wet ingredients ensuring the melted butter has cooled slightly before adding eggs to prevent cooking them. Fold the wet mixture into the dry ingredients using gentle strokes just until combined. Overmixing will develop gluten making your brownies tough rather than tender.
- Bake To Perfection:
- Pour the batter into your prepared pan and spread evenly to the corners. Bake for 22 to 25 minutes watching carefully as overbaking will dry them out. The edges should be just turning golden and a toothpick inserted in the center should come out clean or with a few moist crumbs. Allow to cool completely in the pan on a wire rack.
- Create The Glaze:
- Whisk together powdered sugar, lemon juice, and zest until completely smooth with no lumps. The consistency should be pourable but thick enough to coat a spoon. If too thick add a few drops of lemon juice; if too thin add more powdered sugar a tablespoon at a time.
- Finish And Serve:
- Pour the glaze over the completely cooled brownies and spread to the edges using an offset spatula or the back of a spoon. Let the glaze set for at least 30 minutes before cutting into squares with a sharp knife wiped clean between cuts for the cleanest edges.

The lemon zest is my absolute favorite part of this recipe. I always add a bit more than called for because that intense citrus aroma reminds me of the lemon trees in my grandmother's backyard. She taught me that when it comes to lemon desserts you should be able to smell the sunshine in every bite.
Storage Tips
These lemon brownies will stay fresh at room temperature in an airtight container for up to 3 days. The texture actually improves overnight as the glaze slightly soaks into the top of the brownie creating an even more intense lemon flavor. For longer storage refrigerate for up to a week though the texture will become more dense and fudgelike.

Variation Ideas
While this recipe is perfect as written you can easily customize it to suit your tastes. Try adding blueberries to the batter for a delightful burst of color and flavor. White chocolate chips make a decadent addition that complements the lemon beautifully. For a sophisticated twist add a tablespoon of poppy seeds to the batter and a teaspoon of culinary lavender to the glaze.
Serving Suggestions
These lemon brownies are delicious on their own but become truly special when paired with the right accompaniments. Serve with fresh berries and a dollop of lightly sweetened whipped cream for an elegant dessert. They make a perfect addition to afternoon tea or coffee. For a show stopping dessert trifle crumble the brownies and layer with lemon curd and whipped mascarpone.
