Step 1
Pour 1½ cup of heavy whipping cream, sugar and vanilla into the cold bowl and whisk on high speed until medium to stiff peaks form. Do not over beat. In a bowl, add vanilla pudding mix with cold milk. Whisk for few minutes until the pudding starts to thicken. Stir in Whipped cream.

Arrange approx. 1 sleeve of graham crackers on the bottom of a pan, breaking them as needed to fit around the top and bottom edges. Evenly spread half of the pudding mixture over the crackers. Top with another layer of graham crackers, then the remaining pudding mixture. Top with a final layer of graham crackers.
