Get out a cake stand or other cake pan you'd like to use for the cake. Set aside.
In a large metal bowl, pour the cold heavy whipping cream. Add the white sugar and let sit for 1 minute for sugar to dissolve. Then add vanilla.
Whip the cold whipping cream until stiff peaks form.
Spoon a large heap of whipped cream into bottom of the cake stand or cake pan. Spread evenly across bottom.
On top of cream layer, add Nilla Wafer cookies in a single layer (If you have a pan with edges, break them as needed to form to the shape of your pan - small gaps are okay.)
Repeat by adding another cream layer, then another layer of Nilla Wafers until you are out of cookies or have as many layers as you'd like. Finish the top with a thick layer of whipped cream.
Place in the fridge and chill for 6-8 hours (or overnight).
When ready to serve, top with fresh berries. Cut to serve and enjoy!
