Preheat your oven to 350°F (175°C) and prepare a standard loaf pan by lining it with parchment paper.

In a mixing bowl, combine six large eggs, ½ cup of full-fat Greek yogurt, and ¼ cup of melted butter or coconut oil. Mix until smooth.

In another bowl, stir together 1 tablespoon of baking powder, ¼ teaspoon of salt, and ½ teaspoon of xanthan gum or psyllium husk powder. If using almond flour, add it now and mix.

Carefully fold the dry mixture into the wet ingredients, stirring gently until just combined.

Pour the batter into your prepared loaf pan and bake for 35-45 minutes until golden brown.

Remove the pan from the oven and let the bread cool in the pan for about 10 minutes before transferring to a wire rack.
