Step 1

Preheat oven to 350 degree F. Line a 13x9 baking dish with parchment paper. Set aside.

Step 2

For the crust, combine graham cracker and sugar in food processor. Pulse until fine crumbs. Add in melted butter and pulse until combined. Press into bottom of prepared baking dish.

Step 3

For the cheesecake filling, beat cream cheese with sugar, eggs, and vanilla using the whisk attachment of an electric mixer. Beat until fluffy and smooth, about 3-5 minutes. Pour over graham cracker crust.

Step 4

For the cookie dough, beat butter with sugars for 2 minutes. Add egg, milk and vanilla. Beat until combined. Add in flour, cocoa powder, salt and baking soda and mix until fully blended. Fold in chocolate chips.

Step 5

Drop by large scoop onto top of cheesecake layer. Try to use your fingertips to spread gently (doesn't have to cover cheesecake completely, as it will spread during baking).

Step 6

Bake for 30-35 minutes until cookie dough layer is fully baked. Remove and cool on counter. Once cooled, cover with plastic wrap and refrigerate 4 hours or overnight. Cut and enjoy!
