Ingredients
Method
Preparation
- Preheat your oven to 375°F. Grease and line a 9 inch x 5 inch loaf pan and set it aside.
- In the bowl of a stand mixer fitted with the whisk attachment, beat 2 of the egg whites on high until stiff peaks form. Add the cream of tartar halfway through.
- Scrape the beaten egg whites into a medium bowl and set aside.
- In a separate bowl, combine the flour, xanthan gum, salt, whey powder, and baking powder. Whisk to combine.
Mixing
- In the stand mixer with the paddle attachment, add the butter, honey, vinegar, the remaining 2 egg whites, and milk. Top with the dry ingredients and mix well.
- Add one-third of the whipped egg whites to the dough, and mix until incorporated.
- Gently fold in the remaining egg whites until no white streaks remain.
Baking
- Scrape the dough into the prepared loaf pan and smooth the top with a wet spatula.
- Tent the loaf pan with greased aluminum foil.
- Bake for about 50 to 60 minutes, rotating once during baking.
- Remove the foil and continue baking until the top is golden brown and a toothpick inserted comes out clean.
Cooling
- Let it cool in the pan for a few minutes, then turn it out onto a wire rack to cool completely before slicing.
Notes
Store in an airtight container at room temperature for 3 to 4 days. For longer storage, slice and freeze for up to 3 months. Toast frozen slices for a quick reheat.
