Irish Brown Soda Bread

Preheat oven to 350 degrees. Butter two 9-by-5-inch loaf pans then dust with flour, tapping out excess. Sprinkle bottom of pans with 1 1/2 tablespoons oats.

In a large bowl, whisk together flour, bran flakes, baking powder, baking soda, and salt. In another bowl, whisk together sour cream, sugar, oil, and eggs. Fold sour cream mixture into flour mixture until just combined. Divide batter evenly between prepared pans. Top each loaf with remaining 1 1/2 tablespoons oats, dot with butter, and sprinkle with sugar.

Bake until golden and a toothpick inserted in centers comes out clean, about 40 minutes. Cool completely in the pans.
