Begin by preheating your oven to 350°F (175°C). Allow the oven to fully reach this temperature before placing the bread inside. Proper preheating ensures the batter starts cooking immediately, which helps the bread rise evenly and develop a light texture rather than becoming dense.

Take a standard loaf pan and line it with parchment paper, allowing a little extra paper to hang over the edges. This overhang will make it much easier to lift the bread out of the pan later. Lightly pressing the parchment into the corners helps the batter spread evenly.

Crack the eggs into a large mixing bowl. Using a whisk or hand mixer, whisk the eggs thoroughly for about 30–60 seconds until they become smooth and slightly frothy. This step incorporates air into the mixture, which helps the bread develop a softer and more bread-like texture during baking.

Add the softened cream cheese to the whisked eggs. If the cream cheese is cold and firm, it can create lumps, so it’s best to let it sit at room temperature for a few minutes beforehand. Whisk the mixture until the cream cheese is fully incorporated and the batter becomes smooth and creamy.

Add the shredded mozzarella cheese and protein powder to the bowl. Using a spoon or spatula, gently stir the mixture until everything is evenly distributed. The mozzarella helps give the bread structure, while the protein powder boosts the protein content and contributes to the bread-like consistency.

Sprinkle the baking powder and salt evenly over the mixture. These ingredients help the bread rise slightly and enhance the overall flavor. Stir the batter again until the ingredients are fully combined.

Continue mixing until the batter becomes thick, smooth, and uniform with no large lumps. Take a moment to scrape down the sides of the bowl with a spatula to ensure everything is evenly mixed.

Carefully pour the prepared batter into the lined loaf pan. Try to distribute the mixture evenly across the pan so the bread bakes consistently.

Use a spatula or the back of a spoon to smooth the top of the batter. Leveling the surface helps the bread bake evenly and gives the finished loaf a clean, professional appearance.

Place the loaf pan into the preheated oven and bake for 30–35 minutes. During baking, the bread will gradually rise and develop a golden top. It is ready when the surface feels firm and a toothpick inserted into the center comes out clean.

Once baked, remove the loaf from the oven and allow it to cool in the pan for about 10 minutes. Then gently lift the bread out using the parchment paper and place it on a cooling rack. Let the bread cool completely before slicing, as this helps the structure set and prevents the slices from crumbling.
