Preheat your oven to 350°F (180°C) and line a loaf pan with parchment paper.
Drain and rinse the white beans well, then let them sit for a few minutes to remove excess moisture.
Add the beans, eggs, baking powder, oil, salt, black pepper, and garlic powder to a blender or food processor.
Blend the mixture until it becomes smooth, thick, and creamy, scraping the sides if necessary.
Pour the batter into the prepared loaf pan and spread the top evenly with a spatula.
Bake for 40–45 minutes until the top is lightly golden and the center is fully set.
Remove from the oven and let the bread cool for 10–15 minutes, then slice and serve.
