3 tbsp freshly squeezed lemon juice – A must-have for the tang and brightness that define these bars; fresh is always best!

½ tsp vanilla extract – Offers a warm note that rounds out the lemony flavor profile.

How to Make Lemon Brownie Bars Recipe

Follow these simple steps to prepare this delicious Lemon Brownie Bars Recipe:

Step 1: Preheat and Prep
Set your oven to 350°F (180°C). While it’s heating up, grease an 8×8 inch cake tin and line it with parchment paper, leaving an overhang on two sides for easy removal later. This brownie is serious about making an entrance!

Step 2: Combine Dry Ingredients
In a mixing bowl, sift together the all-purpose flour, cornstarch, and salt. This will help avoid any lumps and create a seamless blend. Set it aside, and let it rest while we work on the tasty stuff.

Step 3: Mix Sugar and Lemon Zest
In a large mixing bowl, add the white sugar and the fresh lemon zest. Get your hands in there and rub the zest into the sugar. The result? A gloriously fragrant sugar with hints of lemon that will make any sweet tooth swoon.

Step 4: Whisk Together Wet Ingredients
Next, pour in the warm melted butter, vegetable oil, eggs, lemon juice, and vanilla extract into the sugar mixture. Using a whisk, mix until smooth. But remember, don’t overdo it; we want a masterpiece, not a rubbery sponge!

Step 5: Combine Wet and Dry Ingredients
Gently fold in the dry mixture you set aside earlier. This part is like a gentle embrace; you want to mix just until the dry ingredients are moistened without overmixing. The batter should be thick and luscious.

Step 6: Bake to Perfection
Pour this delightful batter into your prepared cake pan and give it a gentle tap on the counter to spread it evenly. Slide it into your preheated oven and bake for 22 minutes, or until a toothpick inserted comes out almost clean. Be careful not to over-bake; fudgy is the name of the game!

Let’s talk cooling time here. Once out of the oven, allow it to cool in the tin for 1 to 2 hours. Patience is key!

Step 7: Glaze and Serve
After the brownie bars have cooled, run a knife around the edges for easy lifting. Use the parchment paper overhang to remove the bars. In another bowl, mix the powdered sugar with the remaining lemon juice until smooth and gloriously thick. Spread it over the cooled brownies and let that glaze set for about 30 minutes.

Once set, slice these beauties into squares, gather your friends, and prepare for the taste explosion!
