Melt chocolate in a double boiler or microwave. Consistently stir to ensure the chocolate is not overheating. If using the melting chocolate wafers, follow directions on the back of the bag. See note below.
Line a baking sheet with wax paper. Spread the chocolate evenly over the baking sheet using a spatula to create the desired thickness. This does not need to be perfect as the chocolate will be broken up to create the bark.
Sprinkle the crushed peppermint candy canes, pretzel sticks, mini marshmallows, and the dry-roasted peanuts over the chocolate. No measurements needed! If you need more of one topping, simply sprinkle a little more to desired topping level on top of the chocolate. See note below.
Take another piece of wax paper the same size used to line the baking sheet. Place the wax paper on top of the toppings, and gently press the toppings into the chocolate.
Refrigerate the chocolate on the baking sheet for about 40 minutes or until set and firm. Break into large to medium pieces. Store in an airtight container at cool, room temperature.
