Begin by crushing the Biscoff cookies into fine crumbs using a food processor or a rolling pin in a mixing bowl. Add softened cream cheese, protein powder, and oats, mixing well for 2–3 minutes.

Assess the mixture's consistency; it should hold together when squeezed. If too dry, add a splash of water or milk until the mixture holds together.

Using a tablespoon, scoop out the dough and roll it into 1-inch balls. Place each ball on a parchment-lined baking tray.

Once all the balls are formed, refrigerate for at least 30 minutes to achieve a firmer texture.

After chilling, serve as a nutritious snack or dessert, and store leftovers in an airtight container in the refrigerator.
