Method
Make the cookie dough
- Heat the oven to 350°F.
- Line a 9x13-inch baking pan with parchment paper, leaving overhang on two sides.
- Beat the butter, brown sugar, and 1/2 cup granulated sugar with an electric mixer until fluffy, about 2 minutes.
- Beat in the egg and 2 teaspoons vanilla extract until combined.
- In a medium bowl, whisk together the flour, baking soda, and salt.
- Mix the flour mixture into the butter mixture on low speed just until combined.
- Stir in the chocolate chips.
- Press half of the cookie dough evenly into the prepared pan.
- Bake for 10 to 12 minutes, until the surface looks set but is not browned.
Make the cheesecake filling
- In a clean large bowl, beat the cream cheese until smooth.
- Beat in the remaining 1/2 cup granulated sugar and 1 teaspoon vanilla extract.
- Beat in the eggs one at a time on low speed, just until combined.
Assemble and bake
- Spread the filling over the warm crust.
- Crumble the remaining cookie dough evenly over the top.
- Bake for 35 to 45 minutes, until the cookie topping is golden and the center of the filling reaches 160°F on an instant-read thermometer inserted through a gap in the topping.
- Cool in the pan on a rack for 1 hour.
- Cover and refrigerate for at least 4 hours, until firm.
- Lift the bars from the pan using the parchment overhang.
- Cut into 24 pieces.
Notes
For a creamy filling, beat the eggs in on low speed only until combined. Store covered in the refrigerator for up to 5 days; freeze yes, wrapped bars for up to 2 months. For a gluten-free variation, use a 1:1 gluten-free baking flour.
