In a small sauce pan over medium-high heat, cook apple butter about ten minutes until thickened. Chill until ready to use, or mix over a bowl of ice to cool quickly.
Mix heavy whipping cream until slightly thickened, add vanilla and powdered sugar and beat 3-4 minutes until stiff peaks form.
Fold the apple butter into the whipped cream. Keep folding until fully incorporated.
Spread a layer of the whipped cream mixture in the bottom of a prepared springform pan, or casserole dish.
Add a layer of cookies and cover with another layer of whipped cream.
Continue layering cookies and whipped cream until there is just enough whipped cream for one final layer. (Roughly ¼ - ½ cup)
Cover the top with whipped cream and garnish with crushed cookies if desired.
Cover loosely with plastic wrap and refrigerate for 24 hours.
