Sweet and Tart Lemon Bars

For the crust:
Preheat oven to 350ºF and grease a 9 x 13 baking pan. Set aside.

Place the first 3 ingredients into a food processor and pulse until the butter is pea-sized. Pour the mixture into the greased baking pan. Cover it with a sheet of wax paper (to keep it off your hands) and press it across the bottom of the pan until even and firm.

Bake at 350ºF for 15 minutes. Remove from oven and set aside. Note: At this point the crust will not be completely baked. Keep the oven on.

For the filling:
Place the remaining ingredients, except for the confectioners’ sugar, into a mixing bowl. Beat on low speed until blended and then beat on medium speed for 3 minutes. Pour the filling over the hot crust.

Place it back in the 350ºF oven and bake for an additional 20–25 minutes, or until the filling doesn’t jiggle. Remove from oven.

Cool the bars completely before dusting with confectioners sugar and cutting into bars.
