Whisk together the milk, eggs, salt, powdered sugar, and flour in a large mixing bowl until a smooth batter forms. Transfer the batter to the refrigerator and let it rest for 30 minutes.
Heat the semi-sweet chocolate chips and milk and stir them together until the chocolate chips have melted. Add in the eggs, cocoa powder, powdered sugar, and flour and whisk everything together until a smooth batter forms. Transfer the chocolate batter to the refrigerator and let it rest for 30 minutes.
Preheat the oven to 475°F and remove the chilled batters from the refrigerator. Pour the plain crêpe batter into an oven-safe frying pan or casserole dish, transfer it to the oven, and bake at 475°F for 1–2 minutes. Remove the frying pan or casserole dish from the oven and pour a layer of chocolate crêpe batter on top of the cooked crêpe layer. Transfer the frying pan or casserole dish back to the oven and bake the crêpes for another 1–2 minutes. Repeat this process with the remainder of the batter, then transfer the frying pan or casserole dish to the refrigerator and let the layered crêpes cool for at least 4 hours.
Line an 8-inch springform pan with parchment paper. Crush the Graham crackers, mix them together with the melted butter, and press the mixture down evenly into the base of the springform pan. Transfer the springform pan to the refrigerator and let the Graham cracker crust chill for 1 hour.
Chill the heavy cream and beat it with a hand mixer until it becomes a firm whipped cream. Add in the vanilla extract, powdered sugar, and cream cheese and continue beating until the mixture becomes smooth and creamy. For the best results, make sure the heavy cream and cream cheese are both very cold. It's also helpful to chill the mixing bowl and beaters for the hand mixer beforehand to make sure the whipped cream becomes as firm as possible. Remove the chilled crêpes from the refrigerator and use a meat or bread slicer to slice them into thin strips that are about the length and thickness of bacon.
Use an egg slicer to cut the strawberries into thin slices. Spread some of the cheesecake filling onto all of the layered crêpe strips. Place a series of strawberries next to one another on the crêpe strips, making sure the top end of each slice is facing downwards and about ½ of each slice of strawberry sticks out of the top. Roll each layered crêpe strip up into a snug log to make the strawberry roses.
Remove the springform pan from the refrigerator, fill it about ¾ of the way full with the cheesecake filling, and smooth out the surface of the cheesecake. Carefully press the strawberry roses into the cheesecake filling and decorate the cake with some sprigs of mint. Transfer the layered crêpe cake to the refrigerator and let it chill for 2 hours.
