Add the frozen bananas, cottage cheese, high-protein Greek/Skyr yogurt, Biscoff spread, maple syrup, vanilla, cinnamon, and salt to a high-speed blender or food processor. Blend until completely smooth and creamy. Stop and scrape down the sides as needed. The mixture should look similar to soft-serve ice cream.
