Lemon Bars

I saw this recipe on Cooking Mamas and have wanted to try them for awhile.  They are awesome and easy.  

For the Bottom Layer you will need:


1 Box Lemon Cake mix
1 Stick of Butter (softened)
1 Egg

Mix together and pat down in a 9x13 pan

For the filling you will need:
3 3/4 cups powdered sugar (doesn't need to be level)
1 8oz pkg cream cheese softened
2 Eggs
1 Tablespoon Lemon Extract

Beat together & pour over cake mix & Bake @ 350 for 25 mins or longer, just make sure and watch the top for it to be a light brown color, dust with powdered sugar as soon as they come out of the oven. Make a day ahead if you can they seem to set up a little better.
