Preheat your oven to 350°F (175°C). Line a 9x13 inch baking pan with parchment paper, leaving some overhang on the sides for easy removal
In a mixing bowl, combine 1 cup of flour, 1/2 cup powdered sugar, and 1/4 tsp salt. Add the chilled cannabis-infused butter cubes and mix with an electric mixer or pastry cutter until the mixture resembles coarse crumbs
Press the crust mixture firmly into the prepared baking pan to form an even layer. Bake in the preheated oven for 15-20 minutes, or until lightly golden brown
While the crust is baking, prepare the lemon filling. In a mixing bowl, whisk together 1 cup granulated sugar, 2 tbsp flour, and 1/4 tsp baking powder
Add the eggs, lemon juice, and lemon zest to the sugar mixture. Whisk until smooth and well combined
Pour the lemon filling over the pre-baked crust, spreading it evenly. Return the pan to the oven and bake for an additional 20-25 minutes, or until the filling is set and no longer jiggly in the center
Remove the lemon bars from the oven and let them cool completely in the pan on a wire rack
Once cooled, use the parchment paper overhang to lift the lemon bars out of the pan. Transfer to a cutting board and cut into 16 squares
Dust the tops with powdered sugar before serving, if desired
