Preheat the oven to 220 degrees. Grease a loaf pan L30, B12, H10 and sprinkle with oat flakes.
Chop the carrots into very small pieces. Pour the lukewarm (approx. 35 °) buttermilk onto the carrots.
Pour in the crumbled yeast and stir with the hand mixer on speed 1 for three minutes. Add the rest of the ingredients, except for the oat flakes, and knead with the dough hook for 4 minutes.
Pour the dough into the loaf pan, distribute it evenly and brush with a little water. Spread the remaining oatmeal on top.
Bake the bread at 220 ° C for the first 30 minutes. Then bake for another 20 minutes at 180 ° C.
