Line an 8x8 inch square pan with parchment paper and set aside
Pulse chocolate sandwich cookies in a food processor until the cookies are a fine crumb
Pour in melted butter, add in the salt and pulse until evenly combined
Press the cookie crust into the base of the prepared pan. Set aside while you make the filing
In a separate large bowl, add in the room temperature cream cheese and mix until the texture is light and fluffy (about 2-3 minutes)
Add in the C&H® Powdered Sugar, C&H® Dark Brown Sugar, and vanilla and mix until just combined. Set aside
In another mixing bowl, whip the heavy whipping cream until it reaches stiff peaks. Fold into the cream cheese mixture until evenly combined
Add the chocolate sandwich cookies into a plastic bag and use a rolling pin to break apart until crushed but not a powder. Add them into the cream cheese mixture and fold (you can reserve some at this point to place on top)
Pour over the chocolate cookie crust and smooth with a spatula. Set in the fridge for 2-3 hour or overnight before slicing
