In a large mixing bowl combine rolled oats, Greek yogurt, softened cream cheese, protein powder, honey or maple syrup, vanilla extract, and a pinch of salt.
Stir until thoroughly mixed into a thick, cohesive mixture.
Gently fold in fresh blueberries, taking care not to mash them too much.
Scoop portions of the mixture using a tablespoon or small scoop.
Roll each portion into a ball with clean hands, pressing lightly to form smooth bites.
Arrange the finished bites on a tray lined with parchment or a plate.
Refrigerate the tray for 30–60 minutes until bites firm up and hold shape.
Enjoy chilled or keep refrigerated until serving.
