Preheat oven to 350 degrees.
Line a 9 x 13-inch pan with parchment paper so that it overhangs on the short ends of the pan — this way the bars will easily lift out after baking.
Take slices of cookie dough (or crumble dough with hands) and press together on the bottom of the pan to make one smooth layer.
Mix cream cheese and sugar.
Add eggs, then vanilla.
Pour mixture over the cookie crust and smooth with a spatula.
Top with any candy topping you like.
Note: Alternatively, you can use a second roll of cookie dough and place slices on top of the cream cheese mixture to form another cookie layer.
Don’t worry about neatness, the rounds will bake together here, and looks aren’t important in this recipe.
You have other things on your mind.
Bake for 30 to 35 minutes.
Place in freezer until frozen, then remove from pan and slice into 16 bars or 32 bite-sized squares.
