These were delicious, and I will definitely be made again, especially since my sweet tooth is back! I saw this recipe on several blogs. The original recipe is from The Essential Chocolate Chip Cookbook.
Crust
1 & 1/2 cups graham cracker crumbs
5 tablespoons unsalted butter, melted
2/3 cup miniature semisweet chocolate chips (I didn't have mini, so I used regular sized.)
Preheat oven to 325°F. Butter a 9″-square baking pan. Line pan with parchment paper, leaving enough to extend over the sides. Butter the parchment paper. (I did not use parchment paper, and I had no problems.)
Combine graham cracker crumbs and butter until crumbs are moistened. Stir in chocolate chips. Press crust mixture into bottom of pan. Bake for 6 minutes. Set pan on wire rack to cool.
Cookie Dough
5 tablespoons unsalted butter, at room temperature
1/3 cup packed light brown sugar
3 tablespoons granulated sugar
1/8 teaspoon salt
1 teaspoon vanilla extract
3/4 cup all-purpose flour
1 cup semisweet 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. Mix just until incorporated. Stir in chocolate chips. Set aside.
Filling
10 ounces cream cheese, at room temperature
1/4 cup granulated sugar
1 large egg, at room temperature
1 teaspoon vanilla extract
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.
Bake about 30-35 minutes, or until set. Transfer to wire rack.
(I totally forgot about the chocolate topping... they were just fine without it. I am sure it would make it extra delicious.)
For chocolate topping, melt 1/3 cup semisweet chocolate chips in a double boiler or in the microwave. (Tip: put the chocolate chips into a zipper bag and heat on 50% power for a few minutes. Cut the corner off the bag and squeeze the bag to make drizzling less messy). Use a teaspoon to drizzle chocolate over top of bars. Cool bars in pan completely, about an hour. (Stick the bars in the freezer for 5 minutes to set quickly if you're in a hurry).
Using the edges of the parchment paper, remove bars from pan. Cut into bars (clean the knife after each cut) and serve.
