Inside a plastic bag, crush up 2 large graham crackers. I prefer to have little chunks instead of smashing everything into a fine crumb. Totally up to you how much you pulverize it.
Add half the crumbs to the bottom of the glass. Top with half of the 1/2 cup chocolate pudding, pressing down with spoon to remove any gaps. Top with 1/4 cup marshmallow creme. Sprinkle 1 teaspoon mini chocolate chips on top of marshmallow creme (would look really good too if you mixed them into the marshmallow creme first).
Then, top with the remaining graham cracker crumbs and the remaining chocolate pudding.
To toast your 1 jumbo marshmallow over the burner, stab with two skewers. If you use just one, it will be difficult to rotate as it melts. Hold marshmallow high above the flame because the heat will melt it perfectly - any closer and it will catch on fire. Smash toasted marshmallow on top of final layer of pudding. Serve immediately.
