In a double boiler or heavy-bottomed saucepan, heat chocolate, praline cream, margarine, and cinnamon, stirring until melted and combined.

Remove from heat and stir in the Rice Krispies, mini cookies, pretzels, and marshmallows; mix until coated.

Using a small scooper or tablespoon, drop onto parchment-lined baking sheets and garnish with topping of choice. Allow to set for 30 minutes, then store in a cool place in an airtight container.
