These Orange Bars are packed with orange flavor and seriously sweet!
Preheat oven to 350°F.
In a medium bowl, blend together cubed butter, flour and sugar with a pastry cutter, a food processor, or your hands. Press into the bottom of a 9x13 inch pan lined with parchment paper.
Bake for 15 minutes in the preheated oven, or until the edges are just starting to brown.
In a large bowl, crack eggs and whisk them.
To the eggs, add sugar, flour, orange juice, and orange zest. Whisk well, until no clumps remain. Pour over the baked crust after it is done baking.
Once the filling has been added, bake for an additional 20 minutes. (Do not cover.)
Remove from oven and let bars cool to room temperature. Place in the refrigerator for at 2 hours then dust with confectioners sugar before serving.
Cut into squares and serve.
