Rustic Rhubarb Bread in 75 Minutes

Instructions:

1. Preheat the oven to 350°F (175°C) and grease a 9x5 inch loaf pan.
2. In a large mixing bowl, cream together the softened butter and coconut sugar until light and fluffy.
3. Beat in the egg, Greek yogurt, and vanilla extract until the mixture is smooth and emulsified.
4. Sift the flour, baking powder, and salt directly into the wet mixture.
5. Using a spatula, gently fold the ingredients together until no streaks of dry flour remain.
6. Gently fold in the diced rhubarb pieces, ensuring they are evenly distributed.
7. Pour the batter into the prepared loaf pan.
8. In a small bowl, rub together the streusel ingredients (flour, coconut sugar, cold butter, and cinnamon) with fingertips until crumbly, then sprinkle evenly over the batter.
9. Bake for 55 to 60 minutes, or until the top is mahogany gold and a toothpick inserted into the center comes out with only a few moist crumbs.
