I have been thinking of making a dessert with Limoncello for about a week now. I was going to make cookies (which I will make soon!) but I decided to go with Limoncello bars instead, by request of Ryan. I love this because it incorporates a little bit of American and a little bit of Italian flavors. 
These dessert bars came out very good, but they are very rich. So if you don't have a big sweet tooth, one piece will do it for you. 
Ingredients:
Crust:
- 12 tbs Unsalted Butter (1 1/2 sticks) at room temp
 - 2 Cups All-purpose Flour
 - 1 Cup Confectioners' Sugar
 - 3 tbs Limoncello
 - Pinch of Salt
 
- 1 3/4 Cups Granulated Sugar
 - 6 tbs All-purpose Flour
 - 4 Eggs
 - 4 tbs Lemon Juice
 - 3 tbs Limoncello
 
Preheat oven to 350 degrees. Grease a 9x13 baking pan.
Crust: Combine the confectioners' sugar, flour, and salt in a large bowl. Fold in the butter and limoncello to make a doughy mixture. Evenly press into the greased baking pan until it is a flat layer. 
Bake for 20 minutes. Remove from oven.
Filling: Mix the eggs, sugar, flour, lemon juice and limoncello. You can use a hand mixer or standing mixer. Beat well for about 4-5 minutes. 
Pour over the baked crust.  
Bake for an additional 25 minutes.
Let cool completely, and cut into squares. Sift confectioners' sugar before serving for decoration (optional).
