Instructions:
- Preheat oven to 350°F (175°C). Grease and flour two 8.5 x 4.5-inch loaf pans.
- In a small bowl, combine 65g all-purpose flour, 100g brown sugar, and 2g cinnamon. Rub in 42g chilled cubed butter with fingertips until the mixture resembles coarse sand.

- In a separate small bowl, whisk together 115g melted butter, 225g sour cream, 2 eggs, and 5ml vanilla extract until smooth.
- Gently fold the wet ingredients into the dry ingredients until just combined, being careful not to overmix.
- Fold in the 300g diced rhubarb and 100g chopped walnuts.
- Divide batter evenly between the two prepared loaf pans and sprinkle the streusel topping generously across the surface.
- Bake for 55–65 minutes, or until a toothpick inserted in the center comes out clean and the top is deep golden brown.
