Preheat oven to 350 degrees. Line an 8 inch baking pan with parchment that extends up over the sides a bit.
Press about half the cookie dough into the bottom of the prepared pan.
Beat cream cheese, sugar and egg until smooth. Add cherries and mix on low just until combined. Spread cream cheese mixture evenly over the cookie dough.
Using the remaining cookie dough, break into pieces and crumble over the cream cheese filling. Press down lightly.
Bake for 35 to 40 minutes, until firm to the touch. Remove from the oven and cool on a cooling rack for 30 minutes. Refrigerate until well chilled before cutting into bars,
Notes
Before making each cut, run the knife under hot water and dry with a towel. This will result in clean slices.
