In a food processor, pulse the chocolate graham crackers until they resemble fine crumbs. Add the cream cheese and marshmallow creme and pulse until the consistency of dough. Add 1 teaspoon or so more of cream cheese if the dough is still crumbly.
Using a tablespoon, scoop out the dough and flatten between the palms of your hands. Place a mini marshmallow in the center, wrap the dough around it and roll into a ball. Place on the prepared baking sheet. Repeat until all the dough and marshmallows are gone. You should get around 20 balls. Freeze until firm, 20 to 30 minutes.
Place the chocolate chips in a heat-proof bowl. In a small saucepan, bring the cream to a light simmer. Pour the cream over the chocolate and let sit for about 5 minutes. Then stir with a rubber spatula until a nice smooth consistency.
With a fork, dip each ball into the melted chocolate mixture. Place on the baking sheet and sprinkle with the regular graham cracker crumbs. Repeat with the remaining balls. Refrigerate until the chocolate has set, about 15 minutes.
