Lemon Cheesecake Bars

So I have two lemon cheesecake bars on my "to try" list, and this one looked simpler and faster to make, so therefore, this is the one I decided to make this time around!  I'll try the other one sometime soon and see which one really is better :)  This recipe comes from Peachtree Cooking.  It really is a quick recipe and tastes great!

1 box yellow cake mix
1/3 cup oil
2 eggs
8 oz cream cheese
1/3 c. sugar
1-2 Tbsp. lemon juice

Mix cake mix in a small bowl with oil and one egg until crumbly. Reserve 1/2-1 cup of cake mixture and put aside. Mash remaining mixture into the bottom of a 9x13 pan. Bake in 350 degree oven for 12-15 minutes (this is better underdone!). While baking, mix together until smooth- cream cheese, sugar, remaining egg, and lemon juice (no matter how much lemon juice you put in, its not a huge flavor). As soon as the crust comes out of the oven, spread cream cheese mixture evenly on top and then crumble remaining cake mixture over this. Bake in 350 degree oven for 13 minutes. Cool and cut into bars (I like mine cold, so I keep it in the refrigerator)
