Preheat your oven to 350°F (175°C) and prepare a loaf pan.

In a large mixing bowl, whisk together the eggs, Greek yogurt, and melted butter or coconut oil until smooth and creamy.

Add the baking powder, salt, xanthan gum or psyllium husk, and almond flour (if using) to the wet mixture and stir until combined.

Pour the batter into the prepared loaf pan and smooth the top evenly.

Bake in the preheated oven for 35-45 minutes until golden brown. Check for doneness with a toothpick.

Let the bread cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
