01 - Preheat your oven to 350°F. Line an 8x4 inch loaf pan with parchment paper.
02 - In a medium bowl, whisk together the Greek yogurt and eggs until fully combined and slightly frothy.
03 - In a separate small bowl, sift together the coconut flour, baking powder, and salt.
04 - Add the dry ingredients to the wet mixture and mix thoroughly until smooth. Let the batter sit for 2-3 minutes to allow the coconut flour to absorb moisture.
05 - If using, stir in the apple cider vinegar for extra fluffiness.
06 - Pour the batter into the prepared loaf pan. Smooth the top with a spatula. Sprinkle with seeds if desired.
07 - Bake for 30-35 minutes, or until the bread is golden and a toothpick inserted into the center comes out clean.
08 - Let cool completely in the pan, then remove and slice. Serve as desired.
