Lemon Squares

2 cups flour
1/2 cup icing sugar
1 cup margarine
4 eggs
1 1/2 cups sugar
1/4 cup lemon juice
1 tsp baking powder
1/2 tsp salt

• Mix together flour and icing sugar. Cut in margarine.
• Press into a 9"x16" pan lined with parchment paper. Don't skip this. I promise you will have regrets.
• Bake at 350 for 20 minutes.
• Mix together remaining ingredients and pour over crust. Continue baking for another 20 to 30 minutes, until the top is starting to turn a light golden brown.
• Cool before slicing to prevent the filling from running everywhere you don't want it to go.
• Sprinkle with icing sugar before serving. If you do this too far in advance, the icing sugar may just melt and disappear altogether.
