In a large bowl, or the bowl of a standing mixer, combine the flour, oats, yeast, and salt.
In a small bowl, warm the milk slightly, but not boiling. Add the olive oil, then stir in the water and honey.
Pour the milk mixture into the flour mixture, mixing with a dough hook until it just comes together to form a dough. Knead with the dough hook attachment, for 7-10 minutes, until the dough is smooth and elastic (if you’re making this recipe by hand, the dough will be very sticky at first; flour your hands and work surface generously and be patient). If the dough is still very wet and sticky after 5 minutes of kneading, add more flour, 1 TBSP at a time, until the dough is barely tacky. If the dough is too dry, add water, 1 tsp at a time, to soften it up.
Place the dough in a lightly oiled bowl, cover, and allow to rise until doubled, for about 30-60 minutes.
Once doubled, place the dough on a clean, dry work surface. If the dough is too sticky, lightly flour the surface before continuing. With your fingers, flatten the dough into a 9x12-inch pan. Tightly roll the dough, tucking the ends as needed, into a loaf. Brush the top with the warmed honey and sprinkle with the oats. Allow the loaf to rise in a slightly warm location until doubled, about 30 minutes.
When dough has doubled, preheat oven to 350 degrees (180 C). Bake for 40 to 50 minutes, until the bread is deep golden brown and the internal temperature is about 190-200 degrees. Transfer to a wire cooling rack and allow to cool completely before serving. Slice, serve, & enjoy!
