Preheat Oven: Start by setting your oven to 350°F (175°C). Prepare your loaf pan by either lining it with parchment paper or lightly greasing it to prevent sticking.

Hydrate Powdered Egg Whites: In a spacious mixing bowl, combine the powdered egg whites with water. Whisk the mixture vigorously until it becomes fully hydrated and achieves soft peaks. This process is vital for ensuring the bread attains the desired texture.

Blend in Cottage Cheese: Incorporate the cultured cottage cheese into the egg white mixture. Utilize a hand mixer or a whisk to blend the ingredients thoroughly until the mixture is smooth. The addition of cottage cheese contributes moisture and a subtle tang, enriching the protein content of the bread.

Pour and Smooth: Transfer the batter into the prepared loaf pan. Employ a spatula to level the surface for an even finish.

Bake the Bread: Place the loaf pan in the preheated oven and bake for 40 to 45 minutes, or until the bread is set and the top has developed a golden brown hue. Baking times may vary based on your oven’s characteristics and the size of the loaf pan used.

Cool and Serve: After baking, remove the bread from the oven and let it cool in the pan for approximately 10 minutes. Subsequently, transfer the bread to a wire rack to cool completely. It is advisable to slice the bread once it has cooled, as this will facilitate easier cutting.

Enjoy: Cut the protein bread into slices and enjoy it plain or adorned with your preferred spreads and toppings. This bread serves as an excellent option for a high-protein breakfast or a nutritious snack.
