I needed a easy to make and preferably no bake recipe 4th of July cake and went through all the recipes I know of this sort. Couldn't find exactly what I was looking for so just winged it, lol. It came out wonderful, not too filling and went quite fast, now I have to make another 1 since that was a tester, lol.
In a food processor combine 1/3 cup sugar graham cracker crumbs, cocoa powder and melted butter. Pulse until crumbly and fine. Press crumb mix into a 9" x 13" baking dish and refrigerate 30 mins to set.
In lg bowl, beat cream cheese, lemon zest, lemon juice and vanilla until creamy. In another medium sized bowl, beat remaining sugar and heavy whipping cream until thick and fluffy. Add to cream cheese mix and combine.
Spoon filling over crust, smooth out evenly w/ a spoon. Cover tightly w/ plastic wrap and refrigerate 2-3 hrs. Before serving, arrange strawberries and blueberries to make a flag on top of cake.
