Preheat oven to 350 degrees Fahrenheit. Line muffin tray with paper liners.

In a large bowl, mix cake mix, pudding mix, water, oil, and eggs.

Spoon one tablespoon of batter into each muffin cup. Place a cookie over batter, then fill the rest of each cup until halfway full, approximately a quarter cup of batter. Bake for 18 to 22 minutes. Cool completely.

In a food processor, pulse 15 cookies until finely crushed.

In a medium bowl, fold frosting and cookie crumbs together.

Put the cookies and cream frosting in a piping bag and decorate each cupcake as desired.

Garnish with halved cookies placed upright into frosting.
