Step 1: Crush the Cookies. Place all 36 Oreo cookies into a food processor and pulse until fine crumbs form. No food processor? No problem! Put them in a sturdy zip-top bag and crush with a rolling pin until they are as smushed as possible.
Step 2: Mix Your Base. Add the softened 8 ounces of cream cheese to the Oreo crumbs in the food processor. Pulse until well combined and the mixture starts to come together. If mixing by hand, use a rubber spatula to thoroughly combine the ingredients until smooth.
Step 3: Roll into Balls. Transfer the mixture to a bowl and use a spatula to ensure everything is perfectly blended. Line a baking sheet with parchment paper. Use a 1.5-tablespoon cookie scoop (or your hands) to form small, uniform balls. Roll them gently to create smooth truffles.
Step 4: Chill to Perfection. Place the formed Oreo balls on the lined baking sheet and chill them in the refrigerator or freezer for at least 30 minutes. This crucial step helps them firm up and hold their shape before dipping.
Step 5: Dark Chocolate Dip. In a microwave-safe bowl or using a double boiler, gently melt 10 ounces of dark chocolate melting wafers until smooth and fluid. Dip half of your chilled Oreo balls into the melted dark chocolate, letting any excess drip off. Immediately sprinkle with festive Christmas sprinkles before the chocolate sets. Place them back on the parchment-lined sheet.
Step 6: White Chocolate Finish. Now, melt the 10 ounces of white vanilla melting wafers until smooth, using the same method. Dip the remaining Oreo balls into the white chocolate, again allowing excess to drip. Decorate immediately with more vibrant Christmas sprinkles.
Step 7: Final Chill. Return all the decorated Oreo truffles to the refrigerator and chill until the chocolate coatings are completely firm and set. These delicious no-bake treats are now ready to be enjoyed!
