Prepare the Cream Cheese Mixture: Using a stand mixer with a whisk attachment or an electric hand mixer, beat the heavy cream until stiff peaks begin to form. Transfer the whipped cream to a separate bowl and set aside.
Add the cream cheese, vanilla extract and powdered sugar to the bowl and beat on medium-high speed until smooth and creamy. Add in about 2-3 cups of the whipped cream and beat at low speed to incorporate.
Fold in the remaining whipped cream gently, trying not to deflate the whipped cream and stir until combined.
Assemble The Cake: Spread a very thin layer of the cream cheese mixture on the bottom of a 9x13 inch pan, approx. 3 Tbsp. is what I use. Add a single layer of graham crackers to cover the bottom of the pan. You can break them as needed to cover the entire surface. It usually takes about 7-8 sheets per layer.
Spread about 2 1/4 cup of the cream cheese mixture over top of the crackers in an even layer to cover. Line half of the sliced strawberries over the cream cheese mixture to cover. Repeat this once: graham crackers added over the strawberries, 2 1/4 cup cream cheese mixture, remaining half of strawberries)
After the remaining strawberries are added, cover with a final layer of graham crackers and then cover those with the remaining whipped cream.
Make the Strawberry Crunch Topping: In a food processor, combine the freeze-dried strawberries and Golden oreos and process until a fine crumb mixture. Add in the melted butter and pulse a few times to mix the butter to make a crumble mixture. (You can also use a plastic bag and heavy spoon to break down the cookies and mix the butter in a bowl.)
Sprinkle about 3/4 of the strawberry crunch topping over the top layer of the icebox cake. Reserve the rest for just before serving.
Chill and Serve: Chill for at the very least for about 4-5 hours or until the graham crackers are softened and easy to cut through. I prefer chilling overnight for at least about 12 hours to allow the grahams to really soften and become more cake like.
For ease in slicing, you can freeze for about 30 minutes before serving. Run a sharp knife under hot water and then slice, wiping clean each time and then using a thin metal spatula to scoop slices out. It will get messy though--promise!
Refrigerate leftovers for about 3-4 days.
