Prep the cookies. Place Oreos in a food processor and pulse to fine crumbs. No processor? Put them in a zip-top bag and crush with a rolling pin until sandy with no big chunks.

Mix the filling. Add softened cream cheese to the crumbs. Pulse or stir until a thick, uniform dough forms. It should look like a soft, fudgy paste with no streaks.

Chill briefly. Cover the bowl and refrigerate for 15–20 minutes. This makes the mixture easier to roll and less sticky.

Roll into balls. Scoop about 1 tablespoon per truffle and roll between your palms. Aim for 1-inch balls. Place on a parchment-lined baking sheet.

Freeze to set. Freeze the rolled truffles for 20–30 minutes. Slightly firm centers are easier to dip and won’t crumble in the chocolate.

Melt the chocolate. In a microwave-safe bowl, heat chocolate in 20–30 second bursts, stirring between each, until smooth. If it seems thick, stir in 1–2 teaspoons oil to thin.

Dip the truffles. Using a fork, dip each chilled ball in melted chocolate, tap off excess on the bowl’s edge, and slide back onto the parchment. Work in batches so the centers stay cold.

Decorate. While the coating is still wet, add crushed Oreo crumbs, flaky salt, or sprinkles. For a drizzle, melt a contrasting chocolate and flick it over set truffles.

Set and serve. Let the chocolate firm up at room temperature for 20–30 minutes, or refrigerate for 10–15 minutes. Enjoy once fully set.
