Nuts—Use your favorite nuts to coat the truffle (ex. hazelnuts, pistachios). To prepare the nuts, preheat oven to 350 degrees. Spread nuts evenly on baking sheet and toast in oven for 6 minutes. Remove from oven and hot baking sheet; let cool. Finely chop toasted nuts and pour into a shallow bowl. Immediately upon forming the truffle, roll truffle in nuts, coating thoroughly, and place on baking sheet. Replace in refrigerator to firm, about 1 hour.
Chocolate—Melt 10 oz of good quality chocolate (semisweet or milk chocolate) in the microwave for about 1 minute. Stir chocolate to melt completely. Continue to melt in microwave, 30 seconds at a time, until completely melted. Drop formed truffle into melted chocolate and make sure it is covered on all sides. Lift truffle out of melted chocolate with a fork and place on baking sheet. Replace in refrigerator to firm, about 1 hour.
Cookie toppings—Use your favorite cookie sprinkle toppings either to coat the truffle, similar to the technique used to coat with nuts, or you can sprinkle the toppings on the chocolate used to coat the truffle
Other coating ideas: crushed peppermints; crushed pretzels; toasted coconut; mini chocolate chips
