Prepare Oreo Crumbs: Crush Oreo cookies into fine crumbs using a food processor or a zip-top bag and rolling pin.

Cream the Cream Cheese: In a bowl, beat softened cream cheese with an electric mixer for 2-3 minutes until smooth.

Incorporate Oreo Crumbs: Add Oreo crumbs to the cream cheese mixture and gently fold until combined.

Add Protein Powder: Sprinkle vanilla protein powder and stir until fully integrated into the mixture.

Adjust Consistency: Gradually mix in milk until dough is cohesive but not sticky, about 2-3 tablespoons.

Chill the Dough: Cover the bowl with plastic wrap and refrigerate for at least 30 minutes.

Roll the Protein Balls: Scoop portions of dough using a tablespoon and roll into 1-inch balls.

Coat (Optional): Roll each protein ball in powdered sugar for extra sweetness if desired.

Place on Baking Sheet: Arrange rolled balls on a parchment-lined baking sheet.

Melt Chocolate (Optional): Melt dark chocolate in a microwave-safe bowl for drizzling.

Drizzle with Chocolate (Optional): Drizzle melted chocolate over the protein balls.

Chill Again (Optional): Refrigerate for an additional 15-20 minutes if drizzled with chocolate.

Storage: Transfer protein balls to an airtight container and store in the refrigerator or freeze for longer.
