Ingredients You’ll Need

For the Brownie Base

1/2 cup (115 g) unsalted butter, melted – Provides richness and moisture for a tender crumb
1 cup (200 g) granulated sugar – Sweetens and helps create a chewy texture
2 large eggs, room temperature – Bind the batter and add structure
1 teaspoon vanilla extract – Enhances overall flavor complexity
1 cup (125 g) all-purpose flour – Forms the structural base of the brownies
1/4 teaspoon fine salt – Balances sweetness and sharpens flavors
1 tablespoon fresh lemon zest – Infuses concentrated citrus oils
1/4 cup (60 ml) fresh lemon juice – Adds brightness and acidity

For the Lemon Topping

2 large eggs – Create a custard-like lemon layer
1 cup (200 g) granulated sugar – Sweetens and stabilizes the topping
1/4 cup (30 g) all-purpose flour – Thickens the lemon mixture as it bakes
1/4 cup (60 ml) fresh lemon juice – Provides tangy flavor
1 tablespoon fresh lemon zest – Intensifies lemon aroma
Powdered sugar, for dusting (optional) – Adds a decorative finish

Step-by-Step Instructions

Preheat and prepare the pan
Preheat the oven to 350°F (175°C) and grease or line an 8×8-inch baking pan with parchment. Ensure the lining overhangs the sides for easy removal.

Mix the butter and sugar
Combine melted butter and sugar in a bowl and whisk until glossy and smooth. This step dissolves the sugar and creates a cohesive base.

Incorporate eggs and flavorings
Whisk in the eggs and vanilla until fully emulsified and slightly thickened. A smooth mixture ensures even baking.

Add dry ingredients and lemon
Fold in flour, salt, lemon zest, and lemon juice just until combined. Avoid overmixing to keep the brownies tender.

Bake the brownie base
Spread the batter evenly in the pan and bake for 25–30 minutes until a toothpick shows a few moist crumbs. Cool in the pan for about 30 minutes to firm up the layer.

Prepare the lemon topping
Whisk eggs, sugar, flour, lemon juice, and zest until completely smooth. The mixture should be fluid with no lumps.

Bake the lemon layer
Pour the topping over the cooled base and return to the oven for 20–25 minutes. Bake until the surface is set and lightly golden.

Cool, slice, and serve
Allow the brownies to cool completely before slicing. Dust with powdered sugar and serve chilled or at room temperature.

Recipe Notes & Tips

Use fresh lemons – Bottled juice lacks the essential oils that give vibrant flavor.
Room-temperature eggs – Blend more easily and create a smoother batter.
Do not overbake – Slight softness in the center ensures a fudgy texture.
Cool between layers – A warm base can cause the topping to blend instead of layering.
Line the pan – Parchment prevents sticking and simplifies clean slicing.
Chill before cutting – Refrigeration firms the layers for sharp edges.

Troubleshooting Common Issues

Topping sinks into base – The base was too warm; cool longer before adding
Cracked surface – Oven temperature may be too high; use an oven thermometer
Rubbery texture – Batter was overmixed after adding flour
Too tart flavor – Increase sugar slightly or dust generously with powdered sugar

Why This Recipe Works

This recipe succeeds because it layers two complementary baking techniques: a butter-rich brownie base and a lightly thickened lemon custard topping. The fat in the base tenderizes the crumb, while the eggs and flour in the topping coagulate gently to form a smooth set layer. Lemon acidity balances sweetness and activates flavor perception, creating a dessert that tastes bright without being overpowering. Each serving delivers satisfying richness with a refreshing citrus finish at roughly 220 calories per piece.

Final Thoughts

These lemon brownies offer a refreshing alternative to traditional chocolate desserts, combining indulgent texture with vibrant citrus flavor. Their balanced sweetness and moderate calorie profile make them ideal for sharing, and you can easily adapt the recipe with lighter sugar reductions or fruit-forward variations. Whether served chilled or at room temperature, they deliver consistent flavor, clean slices, and crowd-pleasing appeal.
