In a medium mixing bowl, whisk together the oat flour, vanilla protein powder, and crushed freeze-dried strawberries.
Add the softened cream cheese, maple syrup, and vanilla extract to the dry ingredients.
Mix using a spatula or clean hands until a cohesive dough forms; add almond milk one teaspoon at a time if the mixture is too dry to hold its shape.
Scoop approximately 1 tablespoon of the mixture and roll between palms to form a 1-inch sphere.
Place the balls on a tray lined with parchment paper.
Refrigerate the protein balls for at least 30 minutes to allow the texture to firm up before serving.
