Lemon Brownies:
- 250 g (1¼ cups) caster/superfine or granulated sugar
- Zest of 2 lemons (Ideally, use organic unwaxed lemons)
- 170 g (1½ sticks) unsalted butter, melted and cooled until warm
- 2 US large/UK medium eggs, room temperature
- 2 US large/UK medium egg yolks, room temperature
- ½ tsp vanilla bean paste (or 1 tsp vanilla extract)
- 45 g (3 tbsp) lemon juice, freshly squeezed
- 150 g (1¼ cups) plain gluten free flour blend
- ½ tsp xanthan gum (If your gluten free flour blend already contains xanthan gum, add only ¼ tsp)
- ¼ tsp salt
Lemon Cream Cheese Icing:
- 120 g (1 cup) powdered/icing sugar, sifted
- 55 g (¼ cup) full-fat cream cheese, room temperature
- 10 g (2 tsp) lemon juice, freshly squeezed
- Zest of ½ lemon (Ideally, use organic unwaxed lemons)
- ½ tsp vanilla bean paste (or 1 tsp vanilla extract)
- Prepare Oven and Pan: Adjust the oven rack to the middle position, preheat the oven to 350ºF (180ºC), and line a 9-inch (23cm) square baking pan with parchment paper, leaving overhang to help remove brownies easily later.
- Mix Sugar and Lemon Zest: Add the sugar and lemon zest to a large bowl and rub together with fingertips to release the lemon oils, increasing lemon aroma.
- Add Wet Ingredients: Add melted butter, eggs, egg yolks, and vanilla to the sugar mixture; whisk until well combined and smooth, avoiding aeration to keep brownies fudgy.
- Incorporate Lemon Juice: Stir in freshly squeezed lemon juice thoroughly.
- Combine Dry Ingredients: In a separate bowl, whisk together gluten free flour blend, xanthan gum, and salt.
- Mix Batter: Add dry ingredients to wet ingredients and whisk until you have a smooth, relatively runny batter with no lumps.
- Transfer and Bake: Pour batter into lined baking pan, smooth top, and bake at 350ºF (180ºC) for 20-22 minutes until golden on top, a toothpick inserted comes out mostly clean, and brownies feel soft when gently pressed.
- Cool Brownies: Let the brownies cool completely to room temperature in the pan before applying icing.
- Prepare Lemon Cream Cheese Icing: Combine all icing ingredients in a bowl, whisking until smooth, runny, and lump-free.
- Ice Brownies: Pour the icing over cooled brownies and smooth evenly using a spatula or spoon back.
- Set Icing: Allow icing to set at room temperature for 1-2 hours; it will remain sticky longer due to cream cheese moisture.
- Serve: Once icing has set, use parchment overhang to lift brownies out of pan, slice and serve.
Notes
- Use organic unwaxed lemons for the best flavor and zest quality.
- Do not over-mix or aerate the batter to maintain fudgy texture instead of cakey.
- Leaving parchment paper overhang makes removing brownies simpler and cleaner.
- It’s better to slightly underbake the brownies to keep them moist and fudgy.
- If you want firmer icing, make a simple lemon icing without cream cheese.
- Xanthan gum amount depends on whether your gluten free flour blend contains it.
