Remove 8 Oreos from the package and place on a cutting board.

Step 2

Cut the cookies into small, ¼” pieces, set aside.

Step 3

Put the remaining Oreos into the container of a food processor fit with an “S” blade.

Step 4

Step 7

In a medium bowl, whisk together milk and pudding. Set aside in the refrigerator to solidify.

Step 9

Add powdered sugar and beat until smooth.

Step 10

Add pudding to the butter/cream cheese mixture (make sure it has set before adding), and beat on low speed to combined.

Step 11

Fold in cool whip until the mixture is homogenous (uniform throughout).

Step 12

Layer the pudding mixture and cookies. Start by pouring 2 cups of pudding mixture into the bottom of a trifle dish and spread it until level.

Step 13

Sprinkle ½ cup cookie crumbs and ¼ cup chopped cookies evenly over the pudding.

Step 14

Repeat using 2 cups of pudding, ½ cup cookie crumbs and ¼ cup chopped cookies for each layer.

Step 15

Add gummy worms to each layer as desired, or only add some to the top.

Step 16

Be sure the final layer is cookie crumbs!
