Preheat oven to 350. For a recipe of 12 cookies, lay out 24 Ritz crackers. Spread your desired amount of peanut butter on 12 of the crackers and your desired amount of marshmallow fluff onto the other 12 (if using marshmallows, place 3 small marshmallows on the 12 peanut buttered crackers, leaving the other 12 empty).

Pop them into the oven for a couple of minutes just to warm the peanut butter and marshmallow fluff a bit. Once out of the oven, put the ritz together to make sandwiches, and allow them to cool completely.

While they cool, melt chocolate chips and shortening. If using the microwave, be sure to melt the chocolate in small increments at 50% power, stirring after each time, otherwise the chocolate might seize.

Dip the sandwiches into the melted chocolate with a fork. Tap fork against the side of the bowl to drop any excess chocolate off of the cookies. Allow them to cool on parchment paper. If you want to add anything to the top like honey roasted peanuts (as pictured), sprinkles, graham cracker crumbs, or a drizzle of melted peanut butter chips, do so before the chocolate cools completely.
