While the crust is in the oven make the lemon filling.
In a medium bowl, slightly beat the eggs.
In a separate bowl, mix the flour and sugar together. Then add the sugar mixture to the eggs and mix to incorporate.
Add the lemon juice and lemon zest. Mix on low speed until blended.
When the crust is done baking, pour the lemon filling over top of the crust and return to the oven to bake for another 20 minutes or until the filling is set.
Cool the dessert on a wire rack until completely cooled.
Sprinkle with powdered sugar and cut into bars for serving.
