Add in the vanilla, 1/2 cup of the crushed cookies and 1/2 cup of the mini chocolate chips. Stir slightly, the mini chocolate chips are going to melt as you stir, do not mix completely.
Let stand for 2 minutes or until soft. Fold in remaining whipped cream. Spread over the Crushed cookies; using a spatula make is smooth and if wanted garnish with added whipped cream.
