Step 1

Preheat the oven to 350°Fahrenheit (175°C) and line a 9x13-inch baking pan with parchment paper.

Step 2

For the crust: In a medium bowl, whisk the flour, granulated sugar, and salt, then add the butter. Use a pastry cutter or a knife to cut the butter into the flour mixture. Alternatively, rub it by hand until the mixture resembles coarse crumbs. Stir in the vanilla extract.

Step 3

Press the crust evenly into the prepared baking pan and bake for 15-20 minutes until lightly golden brown.

Step 4

For the Filling: In a separate large bowl, whisk the eggs, sugar, flour, lemon juice, and lemon zest until smooth.

Step 5

When the crust is done, carefully pour the filling over the top and bake for 20-25 minutes, or until the edges are set but still slightly wobbly in the middle.

Step 6

Let the bars cool completely on the counter. Then, chill in the fridge for 1-2 hours.

Step 7

Slice the lemon bars, dust with powdered sugar, and enjoy!
