A graham cracker crust with mini-chocolate chips in it topped with a layer of cheesecake and then loaded with drops of cookie dough. A drizzle of chocolate on top makes it out of this world.
For the Crust: Preheat oven to 325°. Butter a 9"-square baking pan (*I used an 8x11 pan). Line pan with parchment paper, leaving enough to extend over the sides. Butter the parchment paper. Combine graham cracker crumbs and butter until crumbs are moistened. Make sure you mix it well so that the crust isn't too crumbly. Stir in chocolate chips.
Using an electric mixer , mix butter, brown sugar, sugar, salt, and vanilla extract at medium speed until smooth. Decrease mixer speed to low and add flour (Add a little at a time. You might not need all the flour. Just add it until the mixture sticks together). Mix just until incorporated. Stir in chocolate chips. Set aside.
Using an electric mixer, beat cream cheese and sugar just until smooth. Add egg and vanilla extract, beating just until blended. Pour batter into baked crust. Drop cookie dough by teaspoonfuls over the top of the filling. It will seem like a lot of cookie dough but you want some in every piece. Bake about 30 minutes at 325 degrees, or until set. Transfer to wire rack.
For chocolate topping, melt 1/3 cup semisweet chocolate chips in a double boiler or in the microwave. *I think it's easier in the microwave. Put in a ziplock bag in a microwave safe bowl and cook for 30 seconds at a time, mixing within the bag after each interval. Snip off the corner of the bag and drizzle. Add about 1/2 tablespoon of butter if necessary to make chocolate smooth. Drizzle over top of bars.
