Today I am at an utter loss for words...something that does not happen often. I believe I'll let the pictures do the talking.
1.5 c flour
1/2 c confectioner's sugar
3/4 c cold butter
3 large eggs
1 c granulated sugar
1/2 t baking powder
1/2 t salt
3 T flour
1. Preheat oven to 350F. Line a 13x9 pan with foil; lightly grease the foil. (I actually forgot this step; whoops. The bars still came out really easily.)
2. In a bowl, mix 1.5 c flour and 1/2 c confectioner's sugar. Cut in the butter until it resembles coarse crumbs. Transfer to the pan and press firmly onto the bottom, forming the crust. Bake until lightly browned, 15-17 minutes.
3. Grate a teaspoon of lemon peel. A microplane zester works awesome here. Squeeze 1/3 c lemon juice.
4. Beat the eggs until thick and lemon-colored. Whisk in lemon peel and juice, granulated sugar, baking powder, salt, and the 3 tablespoons of flour. Mix them all thoroughly together.
5. Pour the lemon filling onto the warm crust.
6. Bake about 15 minutes, or until the filling is set and golden around the edges. Sift confectioner's sugar over the bars and let cool completely in pan. When they are cool, use the foil as a sort of sling to remove the lemon bars. Cut in bars.
The filling really sets up nicely and the bars are not cloyingly sweet, just sweet enough. The lemon taste really comes through, especially with the zest and all. These guys barely lasted a day in our house..
