These bars are the perfect combination of a crunchy cookie bottom, and firm lemon custard that will melt in your mouth.
Preheat the oven to 350 degrees Fahrenheit. Grease a 9 x 13 inch pan.
Mix the ingredients for the crust together with a large fork or a stand mixer. When it is crumbly, begin to bring it together, forming a ball, with your hands.
Place in the pan and flatten the dough with your hands working it up about a 1/2 inch along the sides. Use the back of a spoon to smooth out.
Bake for 15-20 minutes until very light brown. Let it cool.
Whisk together the ingredients for the filling.
When crust is cool, pour in the pan and bake for 35-40, until the filling is set. Let it cool completely, then dust with powdered sugar and cut.
