Ingredients you’ll need
Here’s a list of ingredients you’ll need to make these bars. You can find my recipe card at the bottom of this post for the complete list with their amounts.
- Unsalted butter: Melted.
- Granulated sugar
- Large egg + 1 large egg yolk
- Freshly-squeezed lemon juice: Store-bought lemon juice can be used if needed.
- Zest of 2 lemons
- Plain/all-purpose flour: Using only a small amount of flour is what makes for extra fudgy bars.
- Salt
For the glaze, you’ll need:
- Icing/powdered sugar
- Fresh lemon juice
How to make Lemon Brownies
To make these bars, simply grab a large mixing bowl and whisk together the melted butter and sugar until combined. Add the egg, egg yolk, lemon juice, and zest, and whisk until smooth and combined.
Add the flour and salt, and fold in until completely combined.
Spread the batter evenly into an 8×8-inch square baking pan lined with parchment paper or foil and bake for 30 – 35 minutes, or until the edges are browned and the centre is no longer jiggly – just set.
Allow to cool completely in the pan on a wire rack before glazing.
TIP: To speed up the cooling time, place the pan in the freezer for 1 hour. The brownies will be completely chilled.
For the glaze, grab a small bowl and whisk together the icing sugar and lemon juice until completely smooth and combined. If the glaze is too runny, add more icing sugar.
Pour over the cooled brownies and spread out evenly. Sprinkle on some lemon zest, or top with lemon slices.
Allow the glaze to set at room temperature or in the fridge before slicing and serving.
The printable recipe card with the full list of ingredients, their measurements, and instructions can be found at the bottom of this post.
NOTE: For best results, I highly recommend using the gram measurements (with a digital scale), rather than the cup measurements. Cup measurements are simply not accurate enough, and I cannot guarantee the best results if you use them.
