Preheat your broiler to prepare the caramelized top later.
In a mixing bowl, whisk together the eggs, skim milk, and vanilla whey protein isolate until fully combined and smooth.
Scrape the seeds from the 1/2 vanilla bean and add them to the mixture along with a pinch of salt and the organic cane sugar, reserving a small pinch of sugar for the topping if desired.
Pour the mixture into a small, oven-safe ramekin or custard dish.
Place the ramekin in a larger baking pan filled with about 1 inch of hot water, creating a water bath (bain-marie) to ensure gentle, even cooking.
Bake in a preheated oven at 325°F for about 25-30 minutes, or until the custard is just set but still slightly wobbly in the center.
Carefully remove the ramekin from the water bath and cool slightly.
Sprinkle a small, even layer of the reserved cane sugar on top of the custard. Using a culinary torch, gently caramelize the sugar until it melts and forms a crisp, golden top, or alternatively, place under the broiler for 2-3 minutes, monitoring closely to avoid burning.
Allow the custard to cool for a few minutes before serving to enjoy the perfect balance of the creamy interior with a crackly caramelized finish.
