Cheesecake Bars

These are an amazing little treat from my favorite new website, America's Test Kitchens!!
Makes an 8-inch Square Dish of Bars- they are so yummy and very easy to make!
*Plan Ahead: The bars need to cool completely (about 2 hours) and chill in the fridge (about 3 hours) before serving.

Crust:
2 cups crushed graham crackers,8 tablespoons butter, melted and cooled, 3 tablespoons light brown sugar, 3 tablespoons all-purpose flour, 1/8 teaspoon salt
Filling:
2 (8-ounce) packages cream cheese, softened, 2/3 cup granulated sugar, 2 large eggs, ¼ cup sour cream, 2 teaspoons fresh lemon juice, 1 teaspoon vanilla extract.

Instructions:
Preheat oven to 325 degrees. Line an 8-inch square baking dish with foil, letting edges hang over the side, and grease foil or spray with cooking spray.
Combine the graham cracker crumbs with the butter, brown sugar, flour and salt and mix well. Sprinkle the mixture into the prepared pan and press into an even layer. Bake the crust until beginning to brown, 12 to 15 minutes. (I cooked for only 10 minutes and it was perfect -my oven cooks a little hot).
Beat the softened cream cheese until smooth in a large bowl, scraping down bowl and beaters as needed. Gradually beat the sugar until incorporated, about 1 minute. Beat in the eggs, one at a time, until completely combined. Beat in the sour cream, lemon juice and vanilla until combined. Pour the filling over the crust.
Bake the bars until the edges are set but the center still jiggles slightly, 35 to 40 minutes. (I cooked 35 minutes and it was just right). Let the bars cool completely in the pan, set on a wire rack, about 2 hours, then cover with foil and refrigerate until chilled, at least 3 hours or up to 24 hours. Remove bars from pan using foil and cut into squares and serve.
