I love anything with lemon, and this is one of my favorites! From BettyCrocker.com.

Crust:

1 pouch (17.5 oz) sugar cookie mix

1/2 cup butter, softened

Filling:

4 eggs, slightly beaten

1 1/2 cups granulated sugar

1/4 cup all-purpose flour

1 tablespoon grated lemon peel

1 teaspoon baking powder

1/2 teaspoon salt

1/4 cup fresh lemon juice (about 1 large lemon or 2 medium)*

Topping:

Powdered sugar

Heat oven to 350 degrees. In large bowl, beat crust ingredients until crumbly. Pour into greased 13X9 pan; press mixture evenly in bottom. Bake 20 minutes or until golden brown. Cool 10 minutes.

While crust cools, in same bowl, stir together all filling ingredients except lemon juice. Stir in lemon juice. Pour mixture over crust.

Bake 25-30 minutes longer or until top is light golden brown. Cool completely. Sprinkle with powdered sugar. Cut into bars.

*To get the most juice out of your lemons, microwave about 30 seconds then lightly squish and roll on counter to soften before juicing.
