Preheat the oven to 325 F. Arrange six ramekins inside a deep baking dish.
Blend the cottage cheese, eggs, milk, vanilla protein powder, maple syrup, vanilla, and salt for 1 to 2 minutes, until completely smooth.
Divide the custard evenly among the ramekins. Pour the hot water into the baking dish around the ramekins, stopping halfway up their sides.
Bake for 28 to 34 minutes, until the edges are set but the centers still have a gentle wobble.
Remove the ramekins from the water and cool for 30 minutes. Refrigerate for at least 3 hours, until thoroughly chilled.
Sprinkle 1 1/2 teaspoons granulated sugar in an even layer over each custard.
Place the ramekins under a preheated broiler for 1 to 2 minutes, watching continuously, until the sugar melts into a deep golden crust. Rest for 2 minutes before serving.
