Line baking sheets with parchment paper or waxed paper to prevent sticking and set them aside for later use.
Break apart the sandwich cookies and cut the cream cheese into chunks. Place the cookies in a food processor and pulse several times until you have fine cookie crumbs. Add the cream cheese chunks to the processor and blend until everything is well combined, forming a thick dough.
Using a cookie scoop, portion the dough into 1-inch balls. Roll each portion between your palms until smooth, then place the balls onto the prepared baking sheets. Refrigerate the truffle balls for one hour to help them firm up before dipping.
Melt the dipping chocolate by microwaving it according to the package directions or using a double boiler on the stove until the chocolate is smooth and fully melted. I like to use a double boiler for even melting.
Dip each chilled truffle ball from Step 3 into the melted chocolate, ensuring it’s fully coated. Place the coated truffle back on the lined baking sheet. While the chocolate is still wet, decorate each truffle by rolling it in shredded coconut or sprinkling it with nuts, sprinkles, crushed peppermint, or extra cookie crumbs. Let the chocolate set before serving.
