    1. Preheat the oven to 350°F and line an 8"x8" square baking dish with a sheet of parchment paper.
    2. In a medium bowl, combine the crust ingredients together using your hands or a fork. Mix until you get a sandy mixture.
    3. Pat the crust down into your prepared baking dish to create one even layer. Bake for 20 minutes or until golden and firm.
    4. Meanwhile, create the filling by whisking all the filling ingredients together. When the crust is done baking, give the filling a quick whisk, then pour the filling into the pan over the crust.
    5. Bake for another 20 to 25 minutes, or until the filling is set. Allow the lemon squares to cool for an hour before refrigerating for 2 hours. Before slicing and serving, feel free to dust the squares with powdered sugar.
