Actually, pretty simple to make! UPDATE: These bars were not very lemony, I would add more lemon juice, but then the filling might be runny. You can experiment.
For the base, mix the butter into the flour and sugar.
Mix with your hands until it clings together.
Press into a 13 × 9 × 2- inch pan.
Bake at 350F for 20-25 minutes, or until lightly browned.
For the filling beat together eggs, sugar and lemon juice.
Sift together flour and baking powder.
Stir in egg mixture.
Pour over baked, cooled crust.
Bake at 350F for 25 minutes.
Cool and sprinkle with powdered sugar.
Cut into bars and enjoy.
