Preheat the oven to 325° and line a 8.5x4.5 loaf pan with parchment paper. You can also use a 9X5 and the bread will just not be as tall.
In a medium bowl, combine the SunButter, water, eggs, and ghee. Mix well. The mixture will be sticky and take a little mixing to come together, but it will be smooth after about several stirs.
Add in the collagen, salt, and baking powder and mix again. Add in the vinegar and stir and then pour into the prepared pan. The dough will be thick and scoop-able. Spread as evenly as possible and bake 35 minutes.
Serve warm if desired, store leftovers in an airtight container on the counter then in the fridge after 2 days.
