Instructions

Prepare the Oven and Pan: Preheat your oven to 350°F (175°C). Line a standard 1 lb loaf pan (approx. 7.5 x 3 inches) with parchment paper, ensuring the paper hangs over the sides for easy removal later.
Combine Dry Ingredients: In a medium mixing bowl, whisk together the sifted coconut flour, whey protein isolate, baking powder, and sea salt until completely uniform and free of lumps.
Whip the Egg Whites: In a large, clean bowl using an electric hand mixer or stand mixer, beat the egg whites on high speed until stiff peaks form. This usually takes 3-4 minutes; the whites should stand up straight when the beaters are lifted.
Mix the Wet Base: In a separate large bowl, whisk the egg yolks with the melted butter, Greek yogurt, almond milk, and apple cider vinegar until the mixture is pale yellow and creamy (about 2 minutes).
Incorporate the Dry: Pour the dry ingredient mixture into the bowl with the yolk mixture. Add about one-quarter of the stiff egg whites. Beat on low speed just until the batter is combined and thick.
Fold for Airiness: Gently fold the remaining egg whites into the batter using a silicone spatula. Use a slow, circular motion to incorporate the whites without deflating them, ensuring a smooth dough that retains its volume.
Bake: Transfer the batter to the prepared loaf pan and smooth the top gently. Bake for 35-40 minutes, or until the top is a deep golden brown and a toothpick inserted into the center comes out clean.
Cool: Allow the bread to cool in the pan for 10 minutes, then lift it out using the parchment paper handles and place it on a wire rack to cool completely before slicing.

Notes

Storage: Store leftovers in an airtight container in the refrigerator for up to 5 days. For longer storage, slice the loaf and freeze with parchment paper between slices for up to 3 months.
Allergy Warning: Contains eggs, dairy (whey, butter, yogurt), and tree nuts (coconut, almond). Ensure your baking powder is gluten-free if required.
