Chocolate Chip Cheesecake Bars

I subscribe to a couple recipe sites, and decided to finally try one of the recipes out. My family loved this dessert!

1/2 cup cold butter
1 pouch (1 lb. 1.5 oz) Betty Crocker oatmeal chocolate chip cookie
mix
1 egg
2 packages (8 oz. each) cream cheese, softened
1 cup sugar
2 eggs
1 teaspoon vanilla

Heat oven to 350°F. Spray bottom of 13x9-inch pan with cooking spray. In large bowl, cut butter into cookie mix using fork or pasty blender. Stir in 1 egg until mixture is crumbly. Gently spoon 3 cups crumb mixture into pan; press into bottom of pan. Bake 15 minutes.

In small bowl, beat cream cheese, sugar, 2 eggs and the vanilla with electric mixer on medium speed until smooth. Pour over cookie crust. Spoon remaining crumb mixture over cream cheese. Bake 25 to 30 minutes or until golden brown and firm to the touch. Cool 30 minutes. Refrigerate at least 2 hours or until chilled. For bars, cut into 9 rows by 4 rows. Store covered in refrigerator.
