Directions:

Step 1:
Preheat oven to 350 degrees F. Line an 8-by-8-inch baking pan with parchment.

Step 2:
Cookie: Mix together Pillsbury Sugar Cookie Mix, butter, and egg in a bowl until well-combined. Press two-thirds of the dough into the pan in an even layer, and reserve the rest of the dough.

Step 3:
Cheesecake: Beat cream cheese, sugar, and egg with a hand mixer until smooth. Add in vanilla, salt, and flour and beat again. Pour cheesecake filling over the cookie layer and smooth with a spatula.

Step 4:
Sprinkle the reserved cookie dough on top of the cheesecake filling.

Step 5:
Bake for 30 minutes, until the top is golden brown. Remove from oven and let cool completely. Refrigerate for 2•3 hours (until chilled) before slicing and serving.
