Immediately sprinkle the tops with the reserved crushed Oreos before the chocolate sets, or leave them plain if you prefer.
Refrigerate the coated truffles for at least 20–30 minutes, or until the chocolate is fully set. Store in an airtight container in the refrigerator for up to 5 days.
For picky eaters and different tastes, there are lots of easy ways to customize these. For kids who don’t love dark chocolate, use milk chocolate or white chocolate for the coating; you can even tint white chocolate with a little food coloring for holidays (red and green for Christmas, pastel colors for Easter, or school colors for a party). If someone in your family prefers less sweetness, try using a dark chocolate coating to balance the sweet Oreo center. You can also use flavored Oreos—mint, peanut butter, or birthday cake—for a fun twist without adding extra ingredients. For a little crunch, roll the freshly dipped truffles in sprinkles, mini chocolate chips, or crushed nuts instead of Oreo crumbs. If you need to plan ahead, make the centers a day in advance and keep them chilled, then let the kids help with dipping and decorating the next day. For a slightly lighter version, you can use reduced-fat cream cheese; the texture will be a bit softer, so chill them well before dipping. And if you don’t want to fuss with dipping at all, simply roll the truffle balls in cocoa powder, powdered sugar, or extra Oreo crumbs for a quick, rustic version that’s just as loved around the table.
