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

In a mixing bowl, combine fresh eggs, Greek yogurt, and melted butter or coconut oil, whisking until smooth.

Add baking powder, salt, and xanthan gum or psyllium husk powder to the wet mixture and stir until well integrated.

Pour the batter into the prepared loaf pan, smoothing the top with a spatula.

Bake in the preheated oven for 35–45 minutes until golden and a toothpick comes out clean.

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