Start by adding your processed graham crackers and melted butter to a bowl. Mix until well combined and the consistency of wet sand. Press into the bottom of a greased 9x13 baking dish. Set in the freezer while you prepare your other layers.
To a mixing bowl add your cream cheese and sugar, beat until fluffy and smooth. Fold in your marshmallow fluff and cool whip.
In a separate bowl add your heavy whipping cream and pudding mix. Beat until fluffy and well combined. Now let's build your lasagna.
Spread your cream cheese mixture evenly over your graham cracker crust. Followed by an even layer of your pudding mixer.
Lastly, top everything with a layer of cool whip. Garnish with marshmallows, Hershey chocolate squares and graham cracker crumbs. Drizzle with additional chocolate if desired. Place in the fridge for 3 hours or overnight.
Serve and enjoy! A cool s’mores treat just in time for summer.
