(Oh and I used LITE cream cheese and they were still phenomenal!)
FYI: I DOUBLED my recipe for a 9x13 pan. The recipe below only makes an 8x8, which will NOT be enough. I'll warn you now. :)

Prep Time: 20 minutes
Cook Time: 30-40 minutes
Time to chill: 2+ hours
Ingredients (9-12 servings)
Crust:
- 1 1/2 cups graham cracker crumbs
- 5 tablespoons unsalted butter, melted
- 5 tablespoons unsalted butter, room temperature
- 1/3 cup packed light brown sugar
- 3 tablespoons granulated sugar
- 1/4 teaspoon salt
- 1 teaspoon pure vanilla extract
- 3/4 cup flour
- 2/3 cup chocolate chips
- 10 oz cream cheese, room temperature
- 1/4 cup sugar
- 1 large egg, room temperature
- 1 teaspoon pure vanilla extract
Instructions
1.
Preheat the oven to 325 F. Line an 8" square baking pan with parchment
paper or foil allowing a little overhang and spray with nonstick cooking
spray. Set aside.
2. Mix the melted
butter and graham cracker crumbs until thoroughly combined. Press the
mixture into the bottom of the prepared pan. Bake in preheated oven for 6
minutes. Remove pan to a cooling rack. Leave your oven on while you
prepare the dough.
3. While the crust is
cooling, prepare the chocolate chip cookie dough. In the bowl of a stand
mixer fitted with the paddle attachment or in a large bowl with an
electric mixer, beat butter, brown sugar, granulated sugar, salt and
vanilla until smooth and thoroughly combined, about 1 minute. Mix in the
flour on low speed, and mix until just incorporated. Mix in the
chocolate chips. Set aside. (*Note: This mixture is going to be
dry...that’s okay. It’s rather like a crumble topping. You’re going to
crumble it on top of the cheesecake layer.)
4.
In the bowl of a stand mixer fitted with the paddle attachment or in a
large bowl with an electric mixer cream together the cream cheese and
sugar until smooth. Mix in the egg and vanilla on low speed just until
incorporated. Pour the cheesecake batter into the prepared crust.
Distribute the cookie dough onto the top of the cheesecake batter in
teaspoon-sized clumps. Be sure to use all of the dough.
5.
Bake for about 30 minutes, until the top feels dry and firm (the cookie
dough) and the entire pan looks set if given a gentle shake. Move bars
to a cooling rack and allow to cool completely. Chill in refrigerator
overnight or for at least a couple hours.
6. Lift the bars out by the overhang and cut into squares for serving.
