Begin by placing the Oreo cookies in a food processor. Pulse them until they achieve a fine, coarse crumb texture—this should take about 30 seconds. Pour the crushed Oreos into a mixing bowl to prepare for the next step.

Add the softened cream cheese to the bowl with the Oreo crumbs. Using a hand mixer, beat the mixture on medium speed until fully combined, which should take about 2 minutes.

Scoop out tablespoons of the Oreo mixture and roll them into 1-inch balls. Place the formed balls on a lined baking sheet, ensuring they’re not touching each other, and freeze for about 30 minutes.

While the Oreo balls freeze, melt your chocolate. Place the melting chocolate in a microwave-safe bowl and heat at 50% power for about 2 minutes, stirring every 30 seconds until smooth.

Once the chocolate is melted, remove the Oreo balls from the freezer. Dip each ball into the melted chocolate, ensuring it's fully coated. Allow excess chocolate to drip off before placing back on the lined baking sheet.

Before the chocolate sets, sprinkle your colorful decorations over the coated Oreo balls. Work quickly to ensure the sprinkles stick.

Finally, return the decorated truffles to the freezer for an additional hour to harden the chocolate coating. Store in an airtight container in the refrigerator or freezer.
