Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat.
Place 1 cup cottage cheese in a blender or food processor and blend until completely smooth. Add the egg and blend just until combined.
In a large bowl, whisk together 1-1/4 cups oat flour, 1/2 cup almond flour, 1/4 cup grated parmesan cheese, 1-1/2 teaspoons baking powder, and 1/2 teaspoon salt until well combined.Add the blended cottage cheese and 1 egg to the dry ingredients. Mix with a wooden spoon or spatula until just combined. The dough should slightly stick to your fingers when touched. If it’s too dry, add a little milk and if it’s too wet, add a little more flour. Pour some oil in your hands and shape the dough into a smooth loaf on a baking sheet. In a small bowl, lightly beat 1 egg white. Brush the top of the loaf lightly with the egg white, then sprinkle with 1 teaspoon sesame seeds.
Bake for 28-32 minutes, or until the crust is golden brown. Let the bread cool completely on a wire rack to allow the interior to set properly. If you slice it while it’s still warm, the center can crush and become gummy.
