1 Cup Flour
1/4 Cup Powdered Sugar
1/2 Cup (one stick) Butter, room temperature
1/8 tsp Salt
Combine all and stir until well blended (I mix with my hands). Scrape mixture into a 9 inch square pan. Press down with fingers until even. Bake at 350 degrees for 18 minutes.
TOP LAYER (Make while bottom is baking):
1 CUP Granulated Sugar
3 TB fresh lemon juice
2 large eggs
1/2 tsp baking powder
1/8 tsp salt
Beat eggs slightly and add other ingredients until well blended and thick. When bottom layer is done, pour the topping over the base and spread evenly with a spatula. Return to the oven (same temperature, 350) and bake for another 20 minutes. Cool and dust with powdered sugar sifted through strainer.
NOTE: I always use a little less sugar then requested. Makes the lemon flavor pop!
