Optional: extra cookie and grated chocolate chips for topping
Instructions
In a bowl on an electric mixer, beat cream cheese, sugar and sour cream until light and fluffy, 2-3 minutes. Scrape sides and bottom of the bowl.
Melt chocolate chips in a microwave (in a microwave safe container), for one minute, on half the power. Stir using a large fork until all smooth. If needed, microwave for another 30 second, again on half the power.
Pour chocolate into cream cheese while beating on medium. Scrape sides and bottom of the bowl and beat for a couple more seconds.
Transfer cheesecake mixture into a piping bag and cut off the tip. (You can attach a tip to make the cheesecake layers pretty, or to swirl the top layer.)
Break up one cookie in each of the three jars. (1 cookie per jar.)
Add some cheesecake over cookie. Repeat with another cookie in each jar and more cheesecake mixture on top.
You can add some cookie crumbles on top of last layer and grate some white chocolate.
