This is Coz and Mom's recipe. I double it and use a half sheet pan. The crust can be sticky so I cover with parchment and press into the sheet pan with a rolling pin or tall glass.
Prep: 1 hrs 40 mins
Directions
1For Crust blend 1 c butter, 2 c flour and 1/2 c powdered sugar. Press into 9 x 13 pan. Bake @ 350 for 15 minutes.
2While crust bakes Beat eggs add sugar, lemon juice and 1/4 c flour. Spread mixture over crust and bake another 25 minutes. Let cool, dust with powdered sugar and cut into squares.
