Preheat your oven to 300°F (150°C) and prepare your baking pan.

In a large mixing bowl, whisk together three eggs and avocado oil until frothy.

Add Greek yogurt to the egg mixture and stir until smooth.

In a separate bowl, whisk together almond flour, protein powder, baking powder, xanthan gum, and salt.

Fold the dry mixture into the wet ingredients until just combined.

Transfer the batter into the prepared baking pan and smooth the top.

Bake in the preheated oven for 50-55 minutes until golden brown.

Let the bread cool in the pan for 15 minutes, then transfer to a wire rack.
