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

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

In a separate bowl, combine baking powder, salt, and xanthan gum (or psyllium husk). If using, mix in almond flour.

Pour the dry mixture into the wet ingredients and gently fold together, avoiding overmixing.

Transfer the batter into the prepared loaf pan, smoothing the top.

Bake for 35 to 45 minutes until golden brown and a toothpick comes out clean.

Cool the bread in the pan for 10 minutes, then transfer to a wire rack to cool completely.
